Atmospheric iron (Fe) deposition to the open ocean affects net primary productivity, nitrogen fixation, and carbon uptake. We investigate changes in soluble Fe (SFe) deposition from the pre\uffe2\uff80\uff90industrial period to the late 21st century using the EC\uffe2\uff80\uff90Earth3\uffe2\uff80\uff90Iron Earth System model. EC\uffe2\uff80\uff90Earth3\uffe2\uff80\uff90Iron considers various sources of Fe, including dust, fossil fuel combustion, and biomass burning, and features comprehensive atmospheric chemistry, representing atmospheric oxalate, sulfate, and Fe cycles. We show that anthropogenic activity has changed the magnitude and spatial distribution of SFe deposition by increasing combustion Fe emissions and atmospheric acidity and oxalate levels. We report that SFe deposition has doubled since the early industrial era, using the Coupled Model Intercomparison Project Phase 6 emission inventory. We highlight acidity as the main solubilization pathway for dust\uffe2\uff80\uff90Fe and oxalate\uffe2\uff80\uff90promoted processing for the solubilization of combustion\uffe2\uff80\uff90Fe. We project a global SFe deposition increase of 40% by the late 21st century relative to present day under Shared Socioeconomic Pathway (SSP) 3\uffe2\uff80\uff937.0, which assumes weak climate change mitigation policies. Conversely, SSPs with stronger mitigation pathways (1\uffe2\uff80\uff932.6 and 2\uffe2\uff80\uff934.5) result in 35% and 10% global decreases, respectively. Despite these differences, SFe deposition increases over the equatorial Pacific and decreases in the Southern Ocean (SO) for all SSPs. We further observe that deposition over the equatorial Pacific and SO are highly sensitive to future changes in dust emissions from Australia and South America, as well as from North Africa. Future studies should focus on the potential impact of climate\uffe2\uff80\uff90 and human\uffe2\uff80\uff90induced changes in dust and wildfires combined.A global biofuels program will potentially lead to intense pressures on land supply and cause widespread transformations in land use. These transformations can alter the Earth climate system by increasing greenhouse gas (GHG) emissions from land use changes and by changing the reflective and energy exchange characteristics of land ecosystems. Using an integrated assessment model that links an economic model with climate, terrestrial biogeochemistry, and biogeophysics models, we examined the biogeochemical and biogeophysical effects of possible land use changes from an expanded global second\uffe2\uff80\uff90generation bioenergy program on surface temperatures over the first half of the 21st century. Our integrated assessment model shows that land clearing, especially forest clearing, has two concurrent effects\uffe2\uff80\uff94increased GHG emissions, resulting in surface air warming; and large changes in the land's reflective and energy exchange characteristics, resulting in surface air warming in the tropics but cooling in temperate and polar regions. Overall, these biogeochemical and biogeophysical effects will only have a small impact on global mean surface temperature. However, the model projects regional patterns of enhanced surface air warming in the Amazon Basin and the eastern part of the Congo Basin. Therefore, global land use strategies that protect tropical forests could dramatically reduce air warming projected in these regions.

FPs are currently prepared by conventional radical polymerization of fluoromonomers. These specialty polymers, produced in low tonnage compared to that of commodity ones, display outstanding properties, such as chemical, oxidative, and thermal resistances, low refractive index, dissipation factor, permittivity, and water absorptivity, and excellent weatherability and durability. More recent routes for their preparations are suggested, controlled or not, leading to random, alternated, block, graft, dendrimers, or multiarm copolymers, as well as their applications ranging from coatings to high performance (thermoplastic) elastomers, energy related\uffe2\uff80\uff90materials (e.g., fuel cell membranes, components for lithium\uffe2\uff80\uff90ion batteries, electroactive devices, and photovoltaics) to original and surfactants, optical devices, organic electronics, composites, and shape memory polymers.
Making agriculture sustainable is a global challenge. In the European Union (EU), the Common Agricultural Policy (CAP) is failing with respect to biodiversity, climate, soil, land degradation as well as socio\uffe2\uff80\uff90economic challenges.
The European Commission's proposal for a CAP post\uffe2\uff80\uff902020 provides a scope for enhanced sustainability. However, it also allows Member States to choose low\uffe2\uff80\uff90ambition implementation pathways. It therefore remains essential to address citizens' demands for sustainable agriculture and rectify systemic weaknesses in the CAP, using the full breadth of available scientific evidence and knowledge.
Concerned about current attempts to dilute the environmental ambition of the future CAP, and the lack of concrete proposals for improving the CAP in the draft of the European Green Deal, we call on the European Parliament, Council and Commission to adopt 10 urgent action points for delivering sustainable food production, biodiversity conservation and climate mitigation.
Knowledge is available to help moving towards evidence\uffe2\uff80\uff90based, sustainable European agriculture that can benefit people, nature and their joint futures.

Life\uffe2\uff80\uff90cycle, cost\uffe2\uff80\uff90benefit, and systems analyses, however, indicate that the expansion of biofuels can have complex effects on, and interactions with, land use and food and fuel prices. This article reviews the economic, environmental, and social benefits and costs of biofuels using experiences from developing countries in Asia. The review reveals the following: (1) biofuels are generally not economically competitive with fossil fuels and government support, though prevailing, is costly and questionable. (2) Although biofuels are generally viewed to be a threat to food security, if properly managed, their development could lead to improved productivity in the agriculture sector over the long term with benefits for rural livelihoods and food security. (3) Even though reducing GHG emissions is a key driver for the development of biofuels, effects in terms of soil quality, biodiversity, and water quality must also be assessed; the environmental benefits of biofuels are debatable and depend on a range of fuel\uffe2\uff80\uff90specific factors, management, and agricultural practices. On the basis of this assessment a range of strategies are suggested to further improve the sustainability of biofuels in Asia. WIREs Clim Change 2013, 4:497\uffe2\uff80\uff93511. doi: 10.1002/wcc.241

The objective of this study was to assess CO2 emissions in the soil surface following tillage abandonment and to investigate some of the underlying soil physical, chemical and biological controls. Maize (Zea mays) was planted under conventional tillage (T) and no-tillage (NT), both without crop residues under smallholder farming conditions in Potshini, South Africa. Intact top-soil (0\u20130.05 m) core samples (N = 54) from three 5 \u00d7 15 m2 plots per treatment were collected two years after conversion of T to NT to evaluate the short-term CO2 emissions. Depending on the treatment, cores were left intact, compacted by 5 and 10 or had surface crusts removed. They were incubated for 20 days with measurements of CO2 fluxes twice a day during the first three days and once a day thereafter. Soil organic C (SOC) content, soil bulk density (\u03c1b), aggregate stability, soil organic matter quality, and microbial biomass and its activity were evaluated at the onset of the incubation. CO2 emissions were 22% lower under NT compared with T with CO2 emissions of 0.9 \u00b1 0.10 vs 1.1 \u00b1 0.10 mg C\u2013CO2 gC\u22121 day\u22121 under NT and T, respectively, suggesting greater SOC protection under NT. However, there were greater total CO2 emissions per unit of surface by 9% under NT compared to T (1.15 \u00b1 0.03 vs 1.05 \u00b1 0.04 g C\u2013CO2 m\u22122 day\u22121). SOC protection significantly increased with the increase in soil bulk density (r = 0.89) and aggregate stability (from 1.7 \u00b1 0.25 mm to 2.3 \u00b1 0.31, r = 0.50), and to the decrease in microbial biomass and its activity (r = \u22120.59 and \u22120.57, respectively). In contrast, the greater NT CO2 emissions per m2 were explained by top-soil enrichment in SOC by 48% (from 12.4 \u00b1 0.2 to 19.1 \u00b1 0.4 g kg\u22121, r = 0.59). These results on the soil controls of tillage impact on CO2 emissions are expected to inform on the required shifts in agricultural practices for enhancing C sequestration in soils. In the context of the study, any mechanism favoring aggregate stability and promoting SOC allocation deep in the soil profile rather than in the top-soil would greatly diminish soil CO2 outputs and thus stimulate C sequestration.", "keywords": ["550", "non travail du sol", "ma\u00efs", "No-tillage", "no-tillage", "[SDU.STU]Sciences of the Universe [physics]/Earth Sciences", "Soil Science", "maize", "7.

The elevated CO 2 treatment (ambient + 350 \u03bcmol mol -1 ) stimulated above-ground biomass of clones Robusta and Beaupre after the first growing season by 55 and 38%, respectively. This increased biomass production under elevated CO 2 was associated with a significant increase in plant height, the latter being the result of enhanced internode elongation rather than an increased production of leaves or internodes. Both an increased leaf area index (LAI) and a stimulated net photosynthesis per unit leaf contributed to a significantly higher stem biomass per unit leaf area, and thus to the increased above-ground biomass production under the elevated CO 2 concentrations in both clones. The larger LAI was caused by a larger individual leaf size and leaf growth rate; the number of leaves was not altered by the elevated CO 2 treatment. The higher net leaf photosynthesis was the result of an increase in the photochemical (maximal chlorophyll fluorescence Fm and photochemical efficiency Fv/Fm ) as well as in the biochemical (increased Rubisco activity) process capacities. No significant differences were found in dark respiration rate, neither between clones nor between treatments, but specific leaf area significantly decreased under elevated CO 2 conditions.", "keywords": ["0106 biological sciences", "15.

This paper reviews the current and future biofuel technologies, and their development impacts (including on the climate) within given policy and economic frameworks. Current technologies make it possible to provide first generation biodiesel, ethanol or biogas to the transport sector to be blended with fossil fuels. Still under-development 2nd generation biofuels from lignocellulose should be available on the market by 2020. Research is active on the improvement of their conversion efficiency. A ten-fold increase compared with current cost-effective capacities would make them highly competitive. Within bioenergy policies, emphasis has been put on biofuels for transportation as this sector is fast-growing and represents a major source of anthropogenic greenhouse gas emissions. Compared with fossil fuels, biofuel combustion can emit less greenhouse gases throughout their life cycle, considering that part of the emitted returns to the atmosphere where it was fixed from by photosynthesis in the first place. Life cycle assessment (LCA) is commonly used to assess the potential environmental impacts of biofuel chains, notably the impact on global warming. This tool, whose holistic nature is fundamental to avoid pollution trade-offs, is a standardised methodology that should make comparisons between biofuel and fossil fuel chains objective and thorough. However, it is a complex and time-consuming process, which requires lots of data, and whose methodology is still lacking harmonisation. Hence the life-cycle performances of biofuel chains vary widely in the literature. Furthermore, LCA is a site- and time- independent tool that cannot take into account the spatial and temporal dimensions of emissions, and can hardly serve as a decision-making tool either at local or regional levels. Focusing on greenhouse gases, emission factors used in LCAs give a rough estimate of the potential average emissions on a national level. However, they do not take into account the types of crop, soil or management practices, for instance. Modelling the impact of local factors on the determinism of greenhouse gas emissions can provide better estimates for LCA on the local level, which would be the relevant scale and degree of reliability for decision-making purposes. Nevertheless, a deeper understanding of the processes involved, most notably emissions, is still needed to definitely improve the accuracy of LCA. Perennial crops are a promising option for biofuels, due to their rapid and efficient use of nitrogen, and their limited farming operations. However, the main overall limiting factor to biofuel development will ultimately be land availability. Given the available land areas, population growth rate and consumption behaviours, it would be possible to reach by 2030 a global 10% biofuel share in the transport sector, contributing to lower global greenhouse gas emissions by up to (IEA, 2006), provided that harmonised policies ensure that sustainability criteria for the production systems are respected worldwide. Furthermore, policies should also be more integrative across sectors, so that changes in energy efficiency, the automotive sector and global consumption patterns converge towards drastic reduction of the pressure on resources. Indeed, neither biofuels nor other energy source or carriers are likely to mitigate the impacts of anthropogenic pressure on resources in a range that would compensate for this pressure growth. Hence, the first step is to reduce this pressure by starting from the variable that drives it up, i.e. anthropic consumptions.", "keywords": ["effet de serre", "BIOFUELS;ENERGY CROPS;PERENNIALS;LCA;GREENHOUSE GASES;CLIMATE CHANGE;POLITICAL AND ECONOMIC FRAMEWORKS;BIOENERGY POTENTIAL;LAND-USE CHANGE;NITROUS OXIDE;CARBON DIOXIDE;AGRICULTURAL PRATICES \u00a0;AGRONOMIE;", "0211 other engineering and technologies", "02 engineering and technology", "7.

The main potential environmental benefit is the net reduction in greenhouse gas (GHG) emissions by the substitution of fossil fuels, while the main potential harm is increased pressure on land use, which can lead to competition for food production, loss of forests and the release of large amounts of carbon from soils and vegetation. The major approaches to environmental risk evaluation are experiments, environmental risk assessment, life cycle analysis, ecosystem services and post-market monitoring; while none are ideal, all these have a potential role in evaluating bioenergy cropping. Major environmental impacts vary greatly between crops, countries and management regimes. Bioenergy cropping has the most positive environmental impact when the crops are productive, have low water and nutrient requirements and can be grown on low-grade and abandoned agricultural land in arrangements that promote biodiversity. Such cropping may be able to supply around 8% of the global energy demand: bioenergy cropping should be seen as one element in a wider strategy for efficient use of land, energy, food and water.", "keywords": ["2.

But this would entail a substantial increase in the scale and intensity of biomass production, which could have negative implications for soil health. Bioenergy can contribute to climate change mitigation through displacement of fossil fuels and potentially through sequestration of carbon. Conversely, the required expansion of bioenergy feedstock production could lead to emissions through loss of soil carbon, especially through indirect land use change (iLUC). The gain or loss of terrestrial carbon is determined by the LUC and systems used for biomass production. In this chapter, we first define bioenergy systems and outline their potential to deliver low-carbon energy. We then describe the opportunities and risks to soil health from bioenergy systems, and finally discuss measures by which these risks can be minimised, and biomass can be produced while protecting and ideally enhancing soil health. While our focus is on the interaction between bioenergy systems and soil health predominantly at a local scale, we also discuss larger scale issues including the intensification of production and how biomass supply will need to meet developing sustainability systems to meet different social and environmental constraints.", "keywords": ["2.

It is clear that not every advertized energy source can lead to a sustainable, humane and environment-friendly path out of a future energy crisis. Our proposal is based on two assertions: that the use of food crops for biofuels is immoral, and that for this purpose using land suitable for growing crops productively is to be avoided. We advocate a focus on new 'extremophile' crops. These would either be wild species adapted to extreme environments which express genes, developmental processes and metabolic pathways that distin- guish them from traditional crops or existing crops genetically modified to withstand extreme environments. Such extrem- ophile energy crops (EECs), will be less susceptible to stresses in a changing global environment and provide higher yields than existing crops. Moreover, they will grow on land that has never been valuable for agriculture or is no longer so, owing to centuries or millennia of imprudent exploitation. Such a policy will contribute to striking a balance between ecosystem protection and human resource management. Beyond that, rather than bulk liquid fuel generation, combus- tion of various biomass sources including extremophiles for generating electrical energy, and photovoltaics-based capture of solar energy, are superbly suitable candidates for powering the world in the future. Generating electricity and efficient storage capacity is quite possibly the only way for a sustainable post-fossil and, indeed, post-biofuel fuel economy.", "keywords": ["2.

Native tallgrass prairie plots (4.5 m diameter) were exposed continuously (24 h) to ambient and twice-ambient CO2 from 1 April to 26 October.

Above- and belowground biomass production and leaf area of fertilized plots were greater with elevated than ambient CO2 in both years. The increase in biomass at high CO2 occurred mainly aboveground in 1991, a dry year, and belowground in 1990, a wet year. Nitrogen concentration was lower in plants exposed to elevated CO2, but total standing crop N was greater at high CO2. Increased root biomass under elevated CO2 apparently increased N uptake. The biomass production response to elevated CO2 was much greater on N-fertilized than unfertilized prairie, particularly in the dry year.

As the use of imported mineral fertilizers is beyond the economic means of resource-poor farmers, research and extension efforts of several projects, institutes and organizations concentrated during the last 15 years on the development and promotion of improved fallows with woody and herbaceous legumes, like Tephrosia sp., Cajanus sp., Crotalaria sp., Sesbania sp., Mucuna sp., and Mimosa sp., planted over one or more seasons as pure green manure, in hedgerows (alley cropping), or on fields as seasonal inter- or relay-crop. Green manuring proved to be a risky enterprise, due to highly variable biomass production and residual effects. Yield increments on-farm of up to 74% in the first season and 46% in the second season did not compensate loss of yields and labour investments during green manuring. Even where biomass production was sufficient, residual effects were in most cases unsatisfactory, due to rapid nutrient leaching (N, K) or inappropriate foliage incorporation on-farm. In researcher-managed trials, residual effects were in general somewhat higher, but more than a mere compensation of lost yields was not possible and farmers' adoption of these labour-intensive technologies was rather low. Due to acute land shortage, farmers were reluctant in allocating land to fallows or hedgerows also, with the exception of fields already out of production. Consequently, the concept of improving soil fertility and crop yields with the help of planted fallows or green manure in rotation failed. Woody legumes might have a future on abandoned fields and in wide spaced contour hedges, mainly for the production of firewood and bean stakes. For soil fertility management, the production and availability of farmyard manure and country-own mineral fertilizers, such as travertin and volcanic ashes should be supported. The question is raised as to whether sustainable agricultural development is possible without a credit system for small farmers, reallocating land and creating off-farm employment.", "keywords": ["0106 biological sciences", "2.

In order to test whether this higher carbon fixation efficiency will translate into increased biomass production under CO2 enrichment we exposed plots of narrow alpine grassland (Swiss Central Alps, 2470 m) to ambient (355 \u03bcl l-1) and elevated (680 \u03bcl l-1) CO2 concentration using open top chambers. Part of the plost received moderate mineral nutrient additions (40 kg ha-1 year-1 of nitrogen in a complete fertilizer mix). Under natural nutrient supply CO2 enrichment had no effect on biomass production per unit land area during any of the three seasons studied so far. Correspondingly, the dominant species Carex curvula and Leontodon helveticus as well as Trifolium alpinum did not show a growth response either at the population level or at the shoot level. However, the subdominant generalistic species Poa alpina strongly increased shoot growth (+47%). Annual root production (in ingrowth cores) was significantly enhanced in C. curvula in the 2nd and 3rd year of investigation (+43%) but was not altered in the bulk samples for all species. Fertilizer addition generally stimulated above-ground (+48%) and below-ground (+26%) biomass production right from the beginning. Annual variations in weather conditions during summer also strongly influenced above-ground biomass production (19-27% more biomass in warm seasons compared to cool seasons). However, neither nutrient availability nor climate had a significant effect on the CO2 response of the plants. Our results do not support the hypothesis that alpine plants, due to their higher carbon uptake efficiency, will increase biomass production under future atmospheric CO2 enrichment, at least not in such late successional communities. However, as indicated by the response of P. alpina, species-specific responses occur which may lead to altered community structure and perhaps ecosystem functioning in the long-term. Our findings further suggest that possible climatic changes are likely to have a greater impact on plant growth in alpine environments than the direct stimulation of photosynthesis by CO2. Counter-intuitively, our results suggest that even under moderate climate warming or enhanced atmospheric nitrogen deposition positive biomass responses to CO2 enrichment of the currently dominating species are unlikely.", "keywords": ["0106 biological sciences", "13.

However, as Earth\uffe2\uff80\uff99s biological carbon sinks also shrink, remediation has become a key part of the narrative for terrestrial ecosystems. In contrast, blue carbon on polar continental shelves have stronger pathways to sequestration and have increased with climate-forced marine ice losses\uffe2\uff80\uff94becoming the largest known natural negative feedback on climate change. Here we explore the size and complex dynamics of blue carbon gains with spatiotemporal changes in sea ice (60\uffe2\uff80\uff93100 MtCyear\uffe2\uff88\uff921), ice shelves (4\uffe2\uff80\uff9340 MtCyear\uffe2\uff88\uff921\uffe2\uff80\uff89=\uffe2\uff80\uff89giant iceberg generation) and glacier retreat (<\uffe2\uff80\uff891 MtCyear\uffe2\uff88\uff921). Estimates suggest that, amongst these, reduced duration of seasonal sea ice is most important. Decreasing sea ice extent drives longer (not necessarily larger biomass) smaller cell-sized phytoplankton blooms, increasing growth of many primary consumers and benthic carbon storage\uffe2\uff80\uff94where sequestration chances are maximal. However, sea ice losses also create positive feedbacks in shallow waters through increased iceberg movement and scouring of benthos. Unlike loss of sea ice, which enhances existing sinks, ice shelf losses generate brand new carbon sinks both where giant icebergs were, and in their wake. These also generate small positive feedbacks from scouring, minimised by repeat scouring at biodiversity hotspots. Blue carbon change from glacier retreat has been least well quantified, and although emerging fjords are small areas, they have high storage-sequestration conversion efficiencies, whilst blue carbon in polar waters faces many diverse and complex stressors. The identity of these are known (e.g. fishing, warming, ocean acidification, non-indigenous species and plastic pollution) but not their magnitude of impact. In order to mediate multiple stressors, research should focus on wider verification of blue carbon gains, projecting future change, and the broader environmental and economic benefits to safeguard blue carbon ecosystems through law.

It will be impossible to reach this goal using corn kernel-based ethanol alone. Pectin-rich biomass, an under-utilized waste product of the sugar and juice industry, can augment US ethanol supplies by capitalizing on this already established feedstock. Currently, pectin-rich biomass is sold (at low value) as animal feed. This review focuses on the three most studied types of pectin-rich biomass: sugar beet pulp, citrus waste and apple pomace. Fermentations of these materials have been conducted with a variety of ethanologens, including yeasts and bacteria. Escherichia coli can ferment a wide range of sugars including galacturonic acid, the primary component of pectin. However, the mixed acid metabolism of E. coli can produce unwanted side products. Saccharomyces cerevisiae cannot naturally ferment galacturonic acid nor pentose sugars but has a homoethanol pathway. Erwinia chrysanthemi is capable of degrading many of the cell wall components of pectin-rich materials, including pectin. Klebsiella oxytoca can metabolize a diverse array of sugars including cellobiose, one degradation product of cellulose. However, both E. chrysanthemi and K. oxytoca produce side products during fermentation, similar to E. coli. Using pectin-rich residues from industrial processes is beneficial because the material is already collected and partially pretreated to facilitate enzymatic deconstruction of the plant cell walls. Using biomass already produced for other purposes is an attractive practice because fewer greenhouse gases (GHG) will be anticipated from land-use changes.", "keywords": ["0301 basic medicine", "2.

We attributed differences in bulk density and SOC among cover types to the inclusion of woodlot soils in the analysis. Paired comparison found few differences between poplar and agricultural crops. Sites with significant comparisons varied in magnitude and direction. Relatively greater SOC was often observed in poplar when native soil carbon was low, but there were important exceptions. Woodlots consistently contained greater SOC than the other crops, especially at depth. We observed little difference between paired poplar and switchgrass, both promising bioenergy crops. There was no evidence of changes in poplar SOC relative to adjacent agricultural soils when considered for stand ages up to 12 years. Highly variable native SOC levels and subtle changes over time make verification of soil carbon sequestration among land cover types difficult. In addition to soil carbon storage potential, it is therefore important to consider opportunities offered by long-term sequestration of carbon in solid wood products and carbon-offset through production of bioenergy crops.

Bio-char was added at 0, 30, 60, and 90 g kg\u22121 soil, and BNF was determined using the isotope dilution method after adding 15N-enriched ammonium sulfate to a Typic Haplustox cropped to a potentially nodulating bean variety (CIAT BAT 477) in comparison to its non-nodulating isoline (BAT 477NN), both inoculated with effective Rhizobium strains. The proportion of fixed N increased from 50% without bio-char additions to 72% with 90 g kg\u22121 bio-char added. While total N derived from the atmosphere (NdfA) significantly increased by 49 and 78% with 30 and 60 g kg\u22121 bio-char added to soil, respectively, NdfA decreased to 30% above the control with 90 g kg\u22121 due to low total biomass production and N uptake. The primary reason for the higher BNF with bio-char additions was the greater B and Mo availability, whereas greater K, Ca, and P availability, as well as higher pH and lower N availability and Al saturation, may have contributed to a lesser extent. Enhanced mycorrhizal infections of roots were not found to contribute to better nutrient uptake and BNF. Bean yield increased by 46% and biomass production by 39% over the control at 90 and 60 g kg\u22121 bio-char, respectively. However, biomass production and total N uptake decreased when bio-char applications were increased to 90 g kg\u22121. Soil N uptake by N-fixing beans decreased by 14, 17, and 50% when 30, 60, and 90 g kg\u22121 bio-char were added to soil, whereas the C/N ratios increased from 16 to 23.7, 28, and 35, respectively.

Consequences of methodological choices and data sensitivity on CFPs of feed ingredients were explored to improve comparison and interpretation of CFP studies. Methods and data for emissions from cultivation and processing, land use (LU), and land use change (LUC) were analyzed. For six ingredients (maize, wheat, palm kernel expeller, rapeseed meal, soybean meal, and beet pulp), CFPs resulting from a single change in methods and data were compared with a reference CFP, i.e., based on IPCC Tier 1 methods, and data from literature. Results show that using more detailed methods to compute N2O emissions from cultivation hardly affected reference CFPs, except for methods to determine leaching (contributing to indirect N2O emissions) in which the influence is about -7 to +12 %. Overall, CFPs appeared most sensitive to changes in crop yield and applied synthetic fertilizer N. The inclusion of LULUC emissions can change CFPs considerably, i.e., up to 877 %. The level of LUC emissions per feed ingredient highly depends on the method chosen, as well as on assumptions on area of LUC, C stock levels (mainly aboveground C and soil C), and amortization period. We concluded that variability in methods and data can significantly affect CFPs of feed ingredients and hence CFPs of livestock products. Transparency in methods and data is therefore required. For harmonization, focus should be on methods to calculate leaching and emissions from LULUC.

A microcosm-based study was conducted to evaluate the effects of chemical fertilizer (CF), digested liquid (DL) and varying concentrations of biogas digested slurry based-biochar along with DL on N2O flux, CO2 flux, soil chemical properties and crop yield for three continuous cropping cycles of komatsuna (Brassica rapa var. perviridis) from April to July 2013. Analyses revealed that DL-treated soils released almost equal cumulative amounts of N2O and CO2 as soils treated with CF. The soil mineral-N contents were also similar for the DL- and CF-treated soils while DL application increased the soluble organic carbon (SOC) content of the soil compared to CF treatment. The application of slurry-based biochar increased N2O and CO2 flux, which, in turn, appeared to depend upon biochar concentration. The application of biochar probably increased the nitrification rate as biochar-treated soils had higher values of NO3 \u2212-N and lower values of NH4 +-N compared to soils not treated with biochar at most of the observations. The SOC content was also the highest in biochar-treated soils. The overall crop yield for three cropping cycles was the highest in DL and biochar at low application rate (BL), and it was lower in CF, biochar at medium (BM) and high (BH) application rate. This study indicates that the application of DL could be an effective strategy to minimize the use of CF, without affecting N2O flux, CO2 flux, soil mineral N, and increasing crop productivity.

The results showed that the total CH4 emissions from PF were 646.3+/-52.1 and 215.0+/-45.4 kg CH4 hm(-2) during the rice-growing period and non-rice period, respectively. Both values were much lower than many previous reports from similar regions in Southwest China. The CH4 emissions in the rice-growing season were more intensive in PF, as compared to RW and RR. Only 33% of the total annual CH4 emission in PF occurred in the non-rice season, though the duration of this season is two times longer than the rice season. The annual mean N2O flux in PF was 4.5+/-0.6 kg N2O hm(-2) yr(-1). The N2O emission in the rice-growing season was also more intensive than in the non-rice season, with only 16% of the total annual emission occurring in the non-rice season. The amounts of N2O emission in PF were ignorable compared to the CH4 emission in terms of the global warming potential (GWP). Changing PF to RW or RR not only eliminated CH4 emissions in the non-rice season, but also substantially reduced the CH4 emission during the following rice-growing period (ca. 58%, P >RR approximate to RW. The GWP of PF is higher than that of RW and RR by a factor of 2.6 and 2.7, respectively. Of the total GWP of CH4 and N2O emissions, CH4 emission contributed to 93%, 65% and 59% in PF, RW and RR, respectively.

Treatments included Whole Tree Harvesting (WTH\u2014of all above ground biomass), Conventional stem-only harvesting (CH) of the first rotation crop, and repeated Fertilisation (FE) after the planting of the second rotation forest. This study demonstrates the soil changes underpinning the reduced second rotation tree productivity on these acidic upland sites under WTH, a further 18 years after the investigation by Proe and Dutch (1994). Overall, WTH increased soil acidity significantly (p < 0.05) and reduced soil base saturation whilst FE reduced soil acidity (p < 0.05) and increased soil base saturation as compared to CH. Soil moisture was significantly higher (p < 0.01) under WTH compared to CH and FE plots. There was no evidence that WTH decreased soil organic carbon (SOC) and soil nitrogen (N), but to the contrary there were significantly (p < 0.01) higher concentrations and stocks of total C and N in the WTH soils compared with CH and FE. The depletion of SOC and N in CH and FE plots was attributed to much higher soil mineralisation rates associated with the brash and fertilisation as compared to the WTH plots, where significantly less soil available NO3\u2013N (p < 0.01) was found. In the long term WTH on peaty gley soils appears positive for soil C and N storage. However, WTH had a long term negative impact on soil and tree nutrition of K+ and P, which are currently at deficient levels, but has had a stabilising effect on tree N nutrition as measured in twigs and needles. These results suggest that whilst WTH lead to a reduction in aboveground tree biomass compared to conventional harvest, these practices on selected soil types and certain sites may be beneficial for soil C and N sequestration. The overall findings of this study imply that cost benefit analyses for each site should be carried out before decisions are made on the appropriate type of forest operations (harvesting and replanting), considering both geology and soils in order to serve both environmental benefits, long term sustainability and the available biomass production for timber and biofuel.", "keywords": ["0106 biological sciences", "2.

Globally, land-use change is a major driver of changes in belowground C storage. The emerging bioenergy industry is likely to drive widespread land-use changes, including the replacement of annually tilled croplands with perennial bioenergy crops, and thereby to impact the climate system through alteration of belowground C dynamics. Mechanistic understanding of how land-use changes impact belowground C storage requires elucidation of changes in belowground C flows; however, altered belowground C dynamics following land-use change have yet to be thoroughly quantified through field measurements. Here, we show that belowground C cycling pathways of establishing perennial bioenergy crops (0- to 3.5-year-old miscanthus, switchgrass, and a native prairie mix) were substantially altered relative to row crop agriculture (corn-soy rotation); specifically, there were substantial increases in belowground C allocation (>400%), belowground biomass (400\u2013750%), root-associated respiration (up to 2,500%), moderate reductions in litter inputs (20\u201340%), and respiration in root-free soil (up to 50%). This more active root-associated C cycling of perennial vegetation provides a mechanism for observed net C sequestration by these perennial ecosystems, as well as commonly observed increases in soil C under perennial bioenergy crops throughout the world. The more active root-associated belowground C cycle of perennial vegetation implies a climate benefit of grassland maintenance or restoration, even if biomass is harvested annually for bioenergy production.", "keywords": ["2.

Prairie systems supported greater microbial biomass and enzyme activity compared with corn systems; fertilized prairie systems had greater microbial activity than unfertilized prairies. The magnitude, and in some cases direction, of differences in response variables among the three managed systems changed seasonally. Overall, microbial biomass and enzyme activity were stimulated by increased C inputs (roots) in prairies and were further enhanced with N additions in fertilized prairies.

We assessed the sequestration potential as well as possible risks and benefits of carbon amendments (16\u00a0\u00b1\u00a04% of soil organic C) from Miscanthus\u00a0\u00d7\u00a0giganteus in different carbonization stages of a temperate grassland soil together with pig slurry: (1) untreated dried biomass (feedstock), (2) hydrothermally carbonized biomass (hydrochar) and (3) pyrolyzed biomass (biochar) in comparison to a control (only pig slurry application). The field study was complemented by a laboratory incubation study, followed by a growth experiment with Lolium perenne. In the field, greenhouse gas emissions (CO2, N2O, and CH4) were monitored weekly over 1.5 years and over three months in the lab. Initial nitrogen losses via ammonia emissions after substrate\u2013slurry application were assessed in an additional greenhouse study. We found that biochar reduced soil and ecosystem respiration in incubation and in the field, respectively. Additionally, biochar improved methane oxidation, though restricted by emissions outbursts due to slurry amendment. It also reduced N2O emissions significantly in the lab study but not in the field. Hydrochar and feedstock proved to be easily degradable in incubation, but had no effect on ecosystem respiration in the field. Feedstock amendment significantly increased N2O emissions in incubation and one year after application likewise in the field. In a growth experiment subsequent to the incubation, only biochar amendment increased L. perenne biomass (+29%) significantly, likely due to N retention. In the field, biochar caused a significant shift in the plant species composition from grasses to forbs, whereas hydrochar significantly reduced yields within two growth periods (2011 and 2012). Ammonia emissions were significantly higher with feedstock and biochar compared to the control or acidic hydrochar. The overall results indicate that biochar is better suited for C sequestration and GHG mitigation in grasslands than hydrochar or the uncarbonized feedstock. However, NH3 emission reductions may only occur when the biochar is neutral or slightly acidic.", "keywords": ["2. Zero hunger", "13. Climate action", "11.

A second objective was to determine the effects of feed intake on CH4 emissions. Eight Angus beef heifers (initial and final body weight, 328 \uffc2\uffb1 28 and 430 \uffc2\uffb1 29 kg) were used. The experiment was designed as a split-plot crossover with two diets and two 8-week periods. The main plot was the diet [dry matter (DM) basis]: high forage (70% barley silage, 30% barley-based concentrate) or high grain (30% barley silage, 70% corn-based concentrate). The sub-plot was the feeding level: unrestricted (ad libitum feed intake, 5% orts) or restricted (65% of ad libitum intake) feed intake. Methane emissions were measured during each sub-plot over 3 d using whole animal chambers. Changing the forage to concentrate ratio and substituting barley for corn did not affect CH4 emissions (141.5 g d-1; P = 0.26), and the average emission was about 10% higher than the emission calculated using the International Panel on Climate Change (IPCC) Tier 1 approach. Methane conversion rate was also similar for both diets [6.23% of gross energy intake (GEI), P = 0.29], and was similar to the value of 6.0 used in the IPCC Tier 2 approach to calculating CH4 emissions from cattle. Restricting intake reduced CH4 emissions (169 vs. 114 g d-1; P < 0.002), with the reduction in CH4 proportional to the decline in intake. Level of intake relative to maintenance energy requirements was moderately inversely related (r = -0.30; P = 0.04) to CH4 (% GEI). The proportion of GEI lost as CH4 declined by 0.77 percentage units per unit increase in level of intake above maintenance. This study shows that supplementing barley-silage-based diets with corn grain to increase diet quality has only small effects on reducing CH4 emissions. In contrast, maximizing feed intake above maintenance energy requirements increases daily CH4 emissions, but improves efficiency of CH4 conversion because CH4, as a percentage of GEI, declined. Thus, feeding cattle for maximum gain is an important CH4 mitigation strategy for the cattle industry as it reduces the proportion of feed energy lost as CH4 each day, as well as, reduces the number of days to market and associated CH4 production.

Grown Under Variable Nitrogen Fertilization Rates", "description": "High and stable biomass yields for long periods (15\u201320\u00a0years) are indispensable for the successful establishment of a well-developed bioenergy sector. However, the effects of management practices, particularly nitrogen fertilization, on productivity and soil organic carbon (SOC) are difficult to understand, especially when considering that continuous harvesting cycles may have cumulative effects on the crop and its resources use capacity. The objective of this study was to evaluate the effects of different N fertilization levels on biomass production and SOC accumulation of giant reed over 16\u00a0years. Every year, starting from the second one, two N fertilization rates were applied: 80 (N80) and 160 (N160)\u2009kg N\u00a0ha\u22121. The control treatment (N0) was unfertilized. Nitrogen content and use capacity, and SOC gains were determined. Mean 16-year biomass yields were 16.2, 17.1, and 19.5\u00a0Mg\u00a0ha\u22121 in the N0, N80, and N160 treatments, respectively. Variable yielding phases were observed in the N160 treatment with declining yields towards the last sampling season, whereas the N0 was characterized by increasing yields up to the fourth growing season; thereafter, declining yields were observed. Nitrogen concentration and removed N in the aboveground harvested biomass increased from N0 to N160 and as the stand become older. Mean total SOC stock gains were 1.0 and 0.6\u00a0Mg C\u00a0ha\u22121\u00a0year\u22121 in the N160 and N0 treatments, respectively. The largest SOC stocks were found in the topsoil, with the largest amount (12\u00a0Mg C\u00a0ha\u22121 in 16\u00a0years) in the N160 treatment. In conclusion, long-term high N fertilization rates result in marginal increments in biomass productivity (about 3\u00a0Mg\u00a0ha\u22121\u00a0year\u22121), but in substantial increments in SOC, especially in surface soil layers. A farmer might prefer to grow giant reed without the burdens of fertilization despite the seemingly benefits on SOC and lower yields of unfertilized plots.", "keywords": ["2.

However, little is known about carbon (C) sequestered in poplar intercropping systems. The main objective of this study is to compare the effects of three poplar intercropping designs (configuration A: 250 trees ha\u22121; configuration B: 167 trees ha\u22121 and configuration C: 94 trees ha\u22121) and two intercropping systems (wheat\u2013corn cropping system and wheat\u2013soybean cropping system) on biomass production and C stocks in poplar intercropping systems. The experiment was conducted at Suqian Ecological Demonstration Garden of fast-growing poplar plantations in northwestern Jiangsu. A significant difference in C concentration was observed among the poplar biomass components investigated (P\u00a0\u2264\u00a00.05), with the highest value in stemwood and the lowest in fine roots, ranging from 459.9 to 526.7\u00a0g\u00a0kg\u22121. There was also a significant difference in C concentration among the different crop components (P\u00a0\u2264\u00a00.05), and the highest concentration was observed in the corn ear. Over the 5-year period, the total poplar biomass increased with increasing tree density, ranging from 8.77 to 15.12\u00a0t\u00a0ha\u22121, while annual biomass production among the crops ranged from 4.69 to 16.58\u00a0t\u00a0ha\u22121 in the three configurations. Overall, total C stock in the poplar intercropping system was affected by configurations and cropping systems, and configuration A obtained the largest total C stock, reaching 16.7\u00a0t\u00a0C\u00a0ha\u22121 for the wheat\u2013soybean cropping system and 18.9\u00a0t\u00a0C\u00a0ha\u22121 for the wheat\u2013corn cropping system. Results from this case study suggest that configuration A was a relative optimum poplar intercropping system both for economic benefits and for C sequestration.", "keywords": ["2.

The use of cover crops could be a potential strategy to ameliorate any adverse effects of residue removal while allowing greater removal levels. Hence, the objective of this study was to determine changes in water erosion potential, soil organic C (SOC) and total N concentration, and crop yields under early- and late-terminated cover crop (CC) combined with five levels of corn residue removal after 3\u00a0years on rainfed and irrigated no-till continuous corn in Nebraska. Treatments were no CC, early- and late-terminated winter rye (Secale cereale L.) CC, and 0, 25, 50, 75, and 100% corn residue removal rates. Complete residue removal reduced mean weight diameter (MWD) of water-stable aggregates (5\u00a0cm depth) by 29% compared to no removal at the rainfed site only, suggesting increased water erosion risk at rainfed sites. Late-terminated CC significantly increased MWD of water-stable aggregates by 27 to 37% at both sites compared to no CC, but early-terminated CC had no effect. The increased MWD with late-terminated CC suggests that CC when terminated late can offset residue removal-induced risks of water erosion. Residue removal and CC did not affect SOC and total soil N concentration. Particulate organic matter increased with late-terminated CC at the irrigated site compared to no CC. Complete residue removal increased irrigated grain yield by 9% in 1\u00a0year relative to no removal. Late-terminated CC had no effect on corn yield except in 1\u00a0year when yield was 8% lower relative to no CC due to low precipitation at corn establishment. Overall, late-terminated CC ameliorates residue removal-induced increases in water erosion potential and could allow greater levels of removal without reducing corn yields in most years, in the short term, under the conditions of this study.", "keywords": ["330", "Plant Biology", "Winter rye", "Horticulture", "Aggregate stability", "Mean weight diameter", "7.

The relative proportion of belowground carbon allocation, however, varies with species, age, ecoclimatic conditions and crown dominance categories of trees. Here we compare the coarse root biomass and nutrient stocks of different stem size/crown class categories of 21-year-old Grevillea robusta stand in Kerala, India and the soil carbon/nutrient stocks of the G. robusta stand with an adjoining unplanted site. Root systems of 18 trees of three stem diameter/crown classes (5\u201315, 15\u201325, and\u00a0>25\u00a0cm: suppressed\u00a0+\u00a0intermediate, co-dominant and dominant crown classes, respectively) were excavated and their coarse root biomass estimated. Mean coarse root biomass ranged from 12.94 to 59.81\u00a0kg tree\u22121 with production of 18.45\u00a0Mg\u00a0ha\u22121 (mean annual increment\u00a0=\u00a00.88\u00a0Mg\u00a0ha\u22121\u00a0year\u22121). Medium sized trees (co-dominant) had the highest root:shoot ratio, followed by intermediate and suppressed crown classes and the dominant trees had the least values, implying persistence strategies of the suppressed, intermediate and co-dominant trees under conditions of resource limitation. Coarse roots accounted for 8.04\u00a0Mg\u00a0ha\u22121 C while soil organic carbon pool (0\u2013100\u00a0cm) was 77.56\u00a0Mg\u00a0ha\u22121 C, as against 66.04\u00a0Mg\u00a0ha\u22121 for contiguous treeless plots.

This study seeks to determine whether higher grain yields and lower nitrous oxide (N 2 O) emissions could be realized concomitantly by optimizing synthetic N rates and straw returning. The effect of fertilizer N rates and straw application on the inter-annual yield-scaled N 2 O emission variations was measured over a three-year period (2011\u20132014) in a maize-wheat cropping system on the North China Plain (NCP). Yield-scaled N 2 O emissions were expressed as g N 2 O-N per Mg grain. Six treatments with three synthetic N levels (zero\u00a0N [N 0 ], optimized N [N opt ] and conventional N [N con ]) and two straw management practices (straw removal [i.e., N 0 , N opt and N con ] and straw return [i.e., N 0 \u00a0+\u00a0S,\u00a0N opt \u00a0+\u00a0S and N con \u00a0+\u00a0S]) were used. Optimized N (N opt , N opt \u00a0+\u00a0S) refers to the use of approximately 50% of the fertilizer N that is used in conventional farming practices (N con , N con \u00a0+\u00a0S), with no significant decrease in grain yields ( P\u00a0> \u00a00.05). Optimized N reduced cumulative N 2 O emissions by 18\u201337%, which in turn significantly decreased yield-scaled N 2 O emissions by 38\u201342% ( P\u00a0 \u00a00.05). The effects of fertilizer N rates and grain yields on cumulative N 2 O emissions are described by linear and exponential models, respectively. Straw return had a positive effect on mean yield-scaled N 2 O emissions both in the maize season and annually. Yield-scaled N 2 O emissions are constructive considering the trade-off between grain yield and N 2 O emission mitigation from intensive crop production. Optimized fertilizer N rate combined with straw return reduced yield-scaled N 2 O emissions significantly in maize-wheat rotations.", "keywords": ["2. Zero hunger", "13.
