The aim of this study was to determine the importance of the three main drivers of climate change (warming, summer drought, and elevated CO2 concentrations) on N2O fluxes from an extensively managed, upland grassland. Over a 2-year period, we monitored N2O fluxes in an in situ ecosystem manipulation experiment simulating the climate predicted for the study area in 2080 (3.5\u00b0C temperature increase, 20% reduction in summer rainfall and atmospheric CO2 levels of 600\u00a0ppm). N2O fluxes showed significant seasonal and interannual variation irrespective of climate treatment, and were higher in summer and autumn compared with winter and spring. Overall, N2O emissions showed a positive correlation with soil temperature and rainfall. Elevated temperature had a positive impact on mean annual N2O fluxes but effects were only significant in 2007. Contrary to expectations, neither combined summer drought and warming nor the simultaneous application of elevated atmospheric CO2 concentrations, summer drought and warming had any significant effect on annual N2O fluxes. However, the maximum N2O flux rates observed during the study occurred when elevated CO2 was combined with warming and drought, suggesting the potential for important, short-term N2O\u2013N losses in enriched CO2 environments. Taken together, our results suggest that the N2O responses of temperate, extensively managed grasslands to future climate change scenarios may be primarily driven by temperature effects.", "keywords": ["ELEVATED ATMOSPHERIC CO2", "550", "warming", "[SDV]Life Sciences [q-bio]", "N2O EMISSIONS", "drought", "01 natural sciences", "FERTILIZATION", "SOIL-MICROORGANISMS", "0105 earth and related environmental sciences", "WATER-CONTENT", "2.

In laboratory studies they have been shown to increase emissions of the potent GHG nitrous oxide (N2O). Here we test whether these earthworm-induced N2O emissions also occur in the field. We quantified N2O emissions in managed grassland in two different seasons (spring and autumn), applying two different types of fertilizer (organic and artificial fertilizer) and under two earthworm densities (175 individuals and 350 individuals m(-2)) of the species Lumbricus rubellus (Hoffmeister). We found an increase in earthworm-induced N2O emissions of 286 and 394% in autumn for low and high earthworm densities (P = 0.044 and P = 0.007, respectively). There were no effects of earthworms on N2O emissions in spring. Fertilizer additions significantly increased cumulative N2O emissions and grass N content in spring and autumn. For grass N content interactions between earthworm addition and fertilizer type existed in both seasons. Our results suggest that the pathways through which earthworms affect N cycling (and thereby N2O emission) differ with weather conditions. We postulate that in spring the dry weather conditions overruled any earthworm effects, whereas in autumn earthworms mainly improved soil aeration and thereby increased both plant N uptake and diffusion of N2O to the atmosphere. While we showed the presence of earthworm-induced N2O emissions in managed grassland under field conditions for the first time, the nature and intensity of the earthworm effect in the field is conditional on soil physicochemical parameters and thereby on meteorological and seasonal dynamics.

We carried out a field experiment over two full winter wheat\u2013summer maize rotations in the North China Plain (NCP) to determine whether this degree of nitrogen reduction will significantly reduce the emissions of nitrous oxide (N2O) and nitric oxide (NO). Three treatments were investigated in the field trial: a control with no nitrogen application, the conventional practice with nitrogen over-application and the optimal practice with a reduced dose of nitrogen by 1/3. Our observations across all treatments over the experimental period reveal significant correlations of the fluxes of either gas with soil temperature and moisture as well as the concentrations of soil ammonium, nitrate and dissolvable organic carbon. There were strong correlations within the functions of the dual Arrhenius and Michaelis\u2013Menten kinetics, giving apparent activation energy values of 40\u201397 and 59\u201392\u00a0kJ\u00a0mol\u22121 for N2O and NO fluxes, respectively. Our results provide annual direct emission factors of 0.48\u20130.96% for N2O and 0.15\u20130.47% for NO and demonstrate a significant correlation between N2O emission induced by fertilization and fertilizer nitrogen use efficiency (NUE). The correlation indicates a significant potential of N2O mitigation via enhancing NUEs. A reduction in the nitrogen dose did not obviously mitigate either the annual NO emission in both rotations or the annual N2O emission in the second one. However, nitrogen reduction significantly decreased the annual total N2O emission by 38% during the first rotation. These inconsistencies in the responses of N2O emission to the reduced nitrogen dose can be attributed to improper fertilization practices, such as broadcasting urea prior to heavy rainfalls or irrigation events during the maize season, which implies a need for further fertilization practice options/techniques in addition to the reduction of nitrogen doses.", "keywords": ["Michaelis\u00e2\u20ac\u201cMenten kinetics", "2.

In this study we report on the greenhouse gas fluxes (CO2, CH4, and N2O) measured using eddy covariance of a short-rotation bioenergy poplar plantation converted from agricultural fields. During the first six months after the establishment of the plantation (June-December 2010) there were substantial CO2, CH4, and N2O emissions (a total of 5.36 +/- 0.52 MgCO2eq ha(-1) in terms of CO2 equivalents). Nitrous oxide loss mostly occurred during a week-long peak emission after an unusually large rainfall. This week-long N2O emission represented 52% of the entire N2O loss during one and an half years of measurements. As most of the N2O loss occurred in just this week-long period, accurately capturing these emission events are critical to accurate estimates of the GHG balance of bioenergy. While initial establishment (June-December 2010) of the plantation resulted in a net CO2 loss into the atmosphere (2.76 +/- 0.16 Mg CO2eq ha(-1)), in the second year (2011) there was substantial net CO2 uptake (-3.51 +/- 0.56 Mg CO2eq ha(-1)). During the entire measurement period, CH4 was a source to the atmosphere (0.63 +/- 0.05 Mg CO2eq ha(-1) in 2010, and 0.49 +/- 0.05 Mg CO2eq ha(-1) in 2011), and was controlled by water table depth. Importantly, over the entire measurement period, the sum of the CH4 and N2O losses was much higher (3.51 +/- 0.52 Mg CO2eq ha(-1)) than the net CO2 uptake (-0.76 +/- 0.58 Mg CO2eq ha(-1)). As water availability was an important control on the GHG emission of the plantation, expected climate change and altered rainfall pattern could increase the negative environmental impacts of bioenergy.

In a field trial, cultivated with wheat, biochar was added to the soil (3 or 6 kg m(-2)) in two growing seasons (2008/2009 and 2009/2010) so to monitor the effect of treatments on microbial parameters 3 months and 14 months after char addition. N(2)O, CH(4) and CO(2) fluxes were measured in the field during the first year after char addition. Biochar incorporation into the soil increased soil pH (from 5.2 to 6.7) and the rates of net N mineralization, soil microbial respiration and denitrification activity in the first 3 months, but after 14 months treated and control plots did not differ significantly. No changes in total microbial biomass and net nitrification rate were observed. In char treated plots, soil N(2)O fluxes were from 26% to 79% lower than N(2)O fluxes in control plots, excluding four sampling dates after the last fertilization with urea, when N(2)O emissions were higher in char treated plots. However, due to the high spatial variability, the observed differences were rarely significant. No significant differences of CH(4) fluxes and field soil respiration were observed among different treatments, with just few exceptions.

As a consequence, its use is becoming widespread. Some of the main factors (water-filled pore space, NH4(+) and NO3(-)) regulating the emissions of greenhouse gases (i.e. N2O, CO2 and CH4) and NO from agroecosystems can easily be manipulated by drip fertigation without yield penalties. In this study, we tested management options to reduce these emissions in a field experiment with a melon (Cucumis melo L.) crop. Treatments included drip irrigation frequency (weekly/daily) and type of N fertilizer (urea/calcium nitrate) applied by fertigation. Crop yield, environmental parameters, soil mineral N concentrations and fluxes of N2O, NO, CH4 and CO2 were measured during 85 days. Fertigation with urea instead of calcium nitrate increased N2O and NO emissions by a factor of 2.4 and 2.9, respectively (P<0.005). Daily irrigation reduced NO emissions by 42% (P<0.005) but increased CO2 emissions by 21% (P<0.05) compared with weekly irrigation. We found no relation between irrigation frequency and N2O emissions. Based on yield-scaled Global Warming Potential as well as NO cumulative emissions, we conclude that weekly fertigation with a NO3(-)-based fertilizer is the best option to combine agronomic productivity with environmental sustainability. Our study shows that adequate management of drip fertigation, while contributing to the attainment of water and food security, may provide an opportunity for climate change mitigation.", "keywords": ["Greenhouse Effect", "0106 biological sciences", "oxide emissions", "Agricultural Irrigation", "Climate Change", "water", "Nitrous Oxide", "n2o emissions", "nitric-oxide", "treated pig slurries", "01 natural sciences", "soil", "12.

under Mediterranean rainfed conditions. We compared an almond monoculture with tillage in all plot surface (MC)
with almond crop with reduced tillage and growth of Capparis spinosa (D1) and almond crop with reduced tillage and
growth of Thymus hyemalis (D2). For two years, soil CO2 and N2O were measured, with soil sampling at the start and
end of the experimental period. Results showed that CO2 emission rates followed the soil temperature pattern, while
N2O emissions were not correlated with temperature nor moisture. Soil CO2 emissions were significantly higher in
MC(87mgm\u22122 h\u22121), with no significant differences between D1 and D2 (69mgm\u22122 h\u22121). Some peaks in CO2 effluxes
were observed after tillage operations during warm days. Soil N2Oemission rateswere not significantly different among
treatments. Cumulative CO2 and CO2 equivalent (CO2e) emissions were significantly highest in MC. When CO2e emissions
were expressed on a crop production basis, D2 showed the significantly lowest values (5080 g kg\u22121) compared to
D1 (50,419 g kg\u22121) and MC (87,836 g kg\u22121), owing to the high thyme yield, additional to the almond yield. No production

We report results from the CLIMAITE experiment, where the effects of these three climate change parameters were investigated solely and in all combinations in a temperate heathland. Field measurements of N 2 O and CH 4 fluxes took place 1\u20132 years after the climate change manipulations were initiated. The soil was generally a net sink for atmospheric CH 4 . Elevated temperature (T) increased the CH 4 uptake by on average 10\u00a0\u03bcg C\u00a0m \u22122 \u00a0h \u22121 , corresponding to a rise in the uptake rate of about 20%. However, during winter elevated CO 2 (CO 2 ) reduced the CH 4 uptake, which outweighed the positive effect of warming when analyzed across the study period. Emissions of N 2 O were generally low ( \u22122 \u00a0h \u22121 ). As single experimental factors, elevated CO 2 , temperature and summer drought (D) had no major effect on the N 2 O fluxes, but the combination of CO 2 and warming (TCO 2 ) stimulated N 2 O emission, whereas the N 2 O emission ceased when CO 2 was combined with drought (DCO 2 ). We suggest that these N 2 O responses are related to increased rhizodeposition under elevated CO 2 combined with increased and reduced nitrogen turnover rates caused by warming and drought, respectively. The N 2 O flux in the multifactor treatment TDCO 2 was not different from the ambient control treatment. Overall, our study suggests that in the future, CH 4 uptake may increase slightly, while N 2 O emission will remain unchanged in temperate ecosystems on well-aerated soils.

In order to document the dynamics and importance of these emissions, soil organicCand mineral N, residue decomposition, soil potential forCO2 emission and climatic dataweremeasured.CO2 emissions were significantly larger in NTon 53% and in CTon 6% of the days. From April to July 2003 and from November 2003 to March 2004, the cumulated CO2 emissions did not differ significantly between CT and NT. However, the cumulated CO2 emissions from August to November 2003 were considerably larger for NT than for CT. Over the entire 331 days of measurement, CT and NT emitted 3160 269 and 4064 138 kgCO2-C ha-1, respectively.The differences in CO2 emissions in the two tillage systems resulted from the soil climatic conditions and the amounts and location of crop residues and SOM. A large proportion of the CO2 emissions in NTover the entiremeasurement period was probably due to the decomposition of old weathered residues.NTtended to emit more N2O than CT over the entiremeasurement period.However differences were statistically significant in only half of the cases due to important variability. N2O emissions were generally less than 5 g N ha-1 day-1, except for a few dates where emission increased up to 21 g N ha-1 day-1. These N2O fluxes represented 0.80, 0.15 and 1.32 0.52 kg N2O-N ha-1 year-1 for CT and NT, respectively. Depending on the periods, a large part of the N2O emissions occurred was probably induced by nitrification, since soil conditions were not favorable for denitrification.

A better understanding of how tillage practices and CC species affect N2O emissions is therefore needed for the development of productive agroecosystems that contribute to climate change mitigation. The objectives of this three-year (2015\u20132017) field experiment on a Udertic Haplustalf soil in the Po Valley were to compare N2O emissions and crop yield of soybean under NT and CT, and to examine how contrasting residues from two CCs (rye, Secale cereale L. vs hairy vetch, Vicia villosa Roth) affect N2O emissions in NT soybean and maize. We hypothesized that N2O emissions would be lower with NT than with CT and with rye residues than with vetch ones. Nitrous oxide was continuously sampled using automatic chambers during three periods (emergence, N-fixation and maturity) over the soybean-cropping season in 2015 and during the entire cropping maize season in 2017. The DNDC model was calibrated (2015 data) and validated (2017 data), and then used to estimate the annual cumulative N2O emissions in different treatments. Overall, N2O emissions in NT were 40\u201355% lower than in CT, for both in situ measurements (Period I) and modelled estimations. These differences could be ascribed to the higher water-filled pore space (WFPS) and soil nitrate availability in CT than in NT.

The Water and Nitrogen Management Model (WNMM) was applied to simulate nitrous oxide (N2O) emissions from a wheat-cropped Vertosol under long-term management of no-till, crop residue retention, and nitrogen (N) fertiliser application in southern Queensland, Australia, from July 2006 to June 2009. For the simulation study, eight treatments of combinations of conventional tillage (CT) or no-till (NT), stubble burning (SB) or stubble retention (SR), and N fertiliser application at nil (0N) or 90 (90N) kg N/ha.year were used. The results indicated that WNMM satisfactorily simulated the soil water content of the topsoil, mineral N content of the entire soil profile (0\uffe2\uff80\uff931.5\uffe2\uff80\uff89m), and N2O emissions from the soil under the eight treatments, compared with the corresponding field measurements. For simulating daily N2O emissions from soil, WNMM performed best for the treatment CT-SB-90N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.48, P\uffe2\uff80\uff89<\uffe2\uff80\uff890.001; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff8910.2\uffe2\uff80\uff89g N/ha.day) and worst for the treatment CT-SB-0N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.03, P\uffe2\uff80\uff89=\uffe2\uff80\uff890.174; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff891.2\uffe2\uff80\uff89g N/ha.day). WNMM predicted N2O emissions from the soil more accurately for the fertilised treatments (i.e. 90N v. 0N), and for the residue retained treatments (SR v. SB). To reduce N2O emissions from the no-till and fertilised treatments, three scenarios were examined: application of nitrification inhibitor, application of controlled-release fertiliser, and deep placement of liquid fertiliser (UAN32). Only the deep placement of UAN32 below the 35\uffe2\uff80\uff89cm depth was effective, and could reduce the N2O emissions from the soil by almost 40%.

Pre-season mineral N was determined in 20 cm sections to 120 cm depth by soil auguring in seven land use systems. Thereafter, sequential soil auguring was done at two-week intervals in plots that previously had 2-year fallows of Acacia angustissima, Sesbania sesban and unfertilized maize to determine mineral N dynamics. Using the static chamber technique, N2O fluxes were also determined in the same plots. Pre-season NH4-N concentrations were > 12 kg N ha-1 in the 0-20 cm layer for treatments that had a pronounced litter layer. NO 3-N concentrations below 60 cm depth were 10 kg N ha-1 layer-1 in the control plots where maize had been cultivated each year. There was a flush of NO 3-N in the Sesbania and Acacia plots with the first rains. Topsoil NO3-N had increased to > 29 kg N ha-1 by the time of establishing the maize crop. This increase in NO3-N in the topsoil was not sustained as concentrations decreased rapidly within three weeks of maize planting, to amounts of 8.6 kg N ha-1 and 11.2 kg N ha -1 for the Sesbania and Acacia plots, respectively. Total NO 3-N leaching losses from the 0-40 cm layer ranged from 29-40 kg ha-1 for Sesbania and Acacia plots within two weeks when 104 mm rainfall was received to an already fully recharged soil profile. Nitrate then accumulated below the 40 cm depth during early season when the maize had not developed a sufficient root length density to effectively capture nutrients. At one week after planting maize, N2O fluxes of 12.3 g N2O-N ha-1 day-1 from Sesbania plots were about twice as high as those from Acacia, and about seven times the 1.6 g N2O-N ha -1 day-1 from maize monoculture. This was at the time when mineral N was at its peak in the topsoil. The unfertilized maize showed consistently low N2O emissions, which never exceeded 2 g N 2O-N ha-1 day-1 for all the eight sampling dates. The decrease of mineral N concentration in the topsoil resulted in reduced N2O fluxes, despite very high soil moisture conditions. Total N2O-N emissions were greatest for Sesbania plots with 0.3 kg ha -1 lost in 56 days. We conclude that, under high rainfall conditions, there is an inherent problem in managing mineral N originating from mineralization of organic materials as it accumulates at the onset of rains, and is susceptible to leaching before the crop root system develops. We did not quantify nitric oxide and N2 gas emissions, but it is unlikely that total gaseous N losses would be significant and contribute to poor N recovery that has been widely reported.", "keywords": ["2.

Maize is a major irrigated crop in Mediterranean areas and its typical intensive management may impact soil nitrous oxide (N2O) emissions. In these irrigated continuous maize systems, the legumes incorporation as well as adjusted nitrogen (N) fertilization might be interesting strategies to reduce soil N2O emissions. The objective of this study was to assess the impact of cropping diversification and different N rates on soil N2O emissions in flooded irrigated maize under Mediterranean conditions. To achieve this, two cropping systems (maize monoculture system, MC; and pea -maize rotation, MP) and 3N rates (unfertilized, 0N; medium rate, MN; and high rate, HN) were evaluated in a field experiment established in NE Spain during 2\uffc2\uffa0years (2019; 2020). During the studied period, the N rate had a significant effect on soil N2O emissions, with a non-linear positive response of cumulative soil N2O emissions to N rates. In both systems, quick and high increases of soil N2O fluxes were observed immediately after the N application reaching 55 and 100\uffc2\uffa0mg N2O-N m\uffe2\uff88\uff922\uffc2\uffa0day\uffe2\uff88\uff921 in MC and MP, respectively. Both years, the pea phase of the MP rotation showed greater cumulative N2O emissions than the fallow of MC. However, N2O losses in the maize phase were similar (2019) or even higher (2020) in MC than in MP. Moreover, in both seasons, the MN treatments showed lower yield-scaled N2O emissions and N emission factor than the HN treatments, being this last lower than 1% in all cases. The results obtained showed that in irrigated Mediterranean conditions the replacement of a fallow by a legume, together with an adjusted N fertilization are favourable strategies to mitigate soil N2O emissions in high-yielding maize systems.

An assessment of the extent to which soils perform a specific function is not only important to appropriately value their current capacity, but also to make well-informed decisions about how and where to change soil management to align the delivered soil functions with societal demands. To obtain an overview of the capacity of soils to perform different functions, accurate and easy-to-use models are necessary. A problem with most currently-available models is that data requirements often exceed data availability, while generally a high level of expert knowledge is necessary to apply these models. Therefore, we developed a qualitative model to assess how agricultural soils function with respect to climate regulation. The model is driven by inputs about agricultural management practices, soil properties and environmental conditions. To reduce data requirements on stakeholders, the 17 input variables are classified into either (1) three classes: low, medium and high or (2) the presence or absence of a management practice. These inputs are combined using a decision tree with internal integration rules to obtain an estimate of the magnitude of N2O emissions and carbon sequestration. These two variables are subsequently combined into an estimate of the capacity of a soil to perform the climate regulation function. The model was tested using data from long-term field experiments across Europe. This showed that the model is generally able to adequately assess this soil function across a range of environments under different management practices. In a next step, this model will be combined with models to assess other soil functions (soil biodiversity, primary productivity, nutrient cycling and water regulation and purification). This will allow the assessment of trade-offs between these soil functions for agricultural land across Europe.", "keywords": ["2.

Potential denitrification was significantly increased by warming, but did not persist over the intermediate sampling. At the intermediate sampling, the relevance of grassland land-use intensity was reflected by increased potential N2O production at sites with higher LUI.

Soil organic carbon (SOC) sequestration in agricultural soils is an important tool for climate change mitigation within the EU soil strategy for 2030 and can be achieved via the adoption of soil management strategies (SMS). These strategies may induce synergistic effects by simultaneously reducing greenhouse gas (GHG) emissions and/or nitrogen (N) leaching. In contrast, other SMS may stimulate emissions of GHG such as nitrous oxide (N2O) or methane (CH4), offsetting the climate change mitigation gained via SOC sequestration. Despite the importance of understanding trade\uffe2\uff80\uff90offs and synergies for selecting sustainable SMS for European agriculture, knowledge on these effects remains limited. This review synthesizes existing knowledge, identifies knowledge gaps and provides research recommendations on trade\uffe2\uff80\uff90offs and synergies between SOC sequestration or SOC accrual, non\uffe2\uff80\uff90CO2 GHG emissions and N leaching related to selected SMS. We investigated 87 peer\uffe2\uff80\uff90reviewed articles that address SMS and categorized them under tillage management, cropping systems, water management and fertilization and organic matter (OM) inputs. SMS, such as conservation tillage, adapted crop rotations, adapted water management, OM inputs by cover crops (CC), organic amendments (OA) and biochar, contribute to increase SOC stocks and reduce N leaching. Adoption of leguminous CC or specific cropping systems and adapted water management tend to create trade\uffe2\uff80\uff90offs by stimulating N2O emissions, while specific cropping systems or application of biochar can mitigate N2O emissions. The effect of crop residues on N2O emissions depends strongly on their C/N ratio. Organic agriculture and agroforestry clearly mitigate CH4 emissions but the impact of other SMS requires additional study. More experimental research is needed to study the impact of both the pedoclimatic conditions and the long\uffe2\uff80\uff90term dynamics of trade\uffe2\uff80\uff90offs and synergies. Researchers should simultaneously assess the impact of (multiple) agricultural SMS on SOC stocks, GHG emissions and N leaching. This review provides guidance to policymakers as well as a framework to design field experiments and model simulations, which can address knowledge gaps and non\uffe2\uff80\uff90intentional effects of applying agricultural SMS meant to increase SOC sequestration.As a controversial strategy to mitigate global warming, biochar application into soil highlights the need for life cycle assessment before large\uffe2\uff80\uff90scale practice. This study focused on the effect of biochar on carbon footprint of rice production. A field experiment was performed with three treatments: no residue amendment (Control), 6 t\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921 corn straw (CS) amendment, and 2.4\uffc2\uffa0t\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0yr\uffe2\uff88\uff921 corn straw\uffe2\uff80\uff90derived biochar amendment (CBC). Carbon footprint was calculated by considering carbon source processes (pyrolysis energy cost, fertilizer and pesticide input, farmwork, and soil greenhouse gas emissions) and carbon sink processes (soil carbon increment and energy offset from pyrolytic gas). On average over three consecutive rice\uffe2\uff80\uff90growing cycles from year 2011 to 2013, the CS treatment had a much higher carbon intensity of rice (0.68\uffc2\uffa0kg CO2\uffe2\uff80\uff90C equivalent (CO2\uffe2\uff80\uff90Ce) kg\uffe2\uff88\uff921\uffc2\uffa0grain) than that of Control (0.24\uffc2\uffa0kg CO2\uffe2\uff80\uff90Ce\uffc2\uffa0kg\uffe2\uff88\uff921 grain), resulting from large soil CH4 emissions. Biochar amendment significantly increased soil carbon pool and showed no significant effect on soil total N2O and CH4 emissions relative to Control; however, due to a variation in net electric energy input of biochar production based on different pyrolysis settings, carbon intensity of rice under CBC treatment ranged from 0.04 to 0.44\uffc2\uffa0kg CO2\uffe2\uff80\uff90Ce\uffc2\uffa0kg\uffe2\uff88\uff921 grain. The results indicated that biochar strategy had the potential to significantly reduce the carbon footprint of crop production, but the energy\uffe2\uff80\uff90efficient pyrolysis technique does matter.

The N2O-N emission during just a single week was 2.7kg N2O-Nha(-1) which represented approximately 42% of the total N2O-N emitted during the 2years of measurements.

Lowest emissions (and even N2O sink) occurred mostly during the end of the second growing season with maximum canopy development, and water table deeper than 80cm. Gross primary production (GPP) explained 68% of the monthly averaged variability in N2O emission from August to December 2011. Probably N uptake by vegetation during the peak of the second growing season limited N2O emission, which in fact increased again after the plantation was coppiced.

Long\uffe2\uff80\uff90term effects of elevated atmospheric CO2 on the ammonia\uffe2\uff80\uff90oxidizing and denitrifying bacteria in a grassland soil were investigated to test whether a shift in abundance of these N\uffe2\uff80\uff90cycling microorganisms was responsible for enhanced N2O emissions under elevated atmospheric CO2. Soil samples (7.5\uffc2\uffa0cm increments to 45\uffc2\uffa0cm depth) were collected in 2008 from the University of Giessen Free Air Carbon dioxide Enrichment (GiFACE), a permanent grassland exposed to moderately elevated atmospheric CO2 (+20%) since 1998. GiFACE plots lay on a soil moisture gradient because of gradually changing depth to the underlying water table and labeled as the DRY block (furthest from water table), MED block (intermediate to water table), and WET block (nearest to water table). Mean N2O emissions measured since 1998 have been significantly higher under elevated CO2. This study sought to identify microbial and biochemical parameters that might explain higher N2O emissions under elevated CO2. Soil biochemical parameters [extractable organic carbon (EOC), dissolved organic nitrogen (DON), NH4+, NO3\uffe2\uff88\uff92], and abundances of genes encoding the key enzymes involved in ammonia oxidation (amoA) and denitrification (nirK, nirS, nosZ) depended more on soil depth and block (underlying soil moisture gradient) than on elevated CO2. Ammonia oxidation and denitrification gene abundances, relative abundances (ratios) of nirS to nirK, of nosZ to both nirS and to nirK, and of the measured soil biochemical properties DON and NO3\uffe2\uff88\uff92 tended to be lower in elevated CO2 plots as compared with ambient plots in the MED and WET blocks while the DRY block exhibited an opposite trend. High N2O emissions under elevated CO2 in the MED and WET blocks correlated with lower nosZ to nirK ratios, suggesting that increased N2O emissions under elevated CO2 might be caused by a higher proportion of N2O\uffe2\uff80\uff90producing rather than N2O consuming (N2 producing) denitrifiers.

Earthworm activity is known to increase emissions of nitrous oxide (N 2 O) from arable soils. Earthworm gut, casts, and burrows have exhibited higher denitrification activities than the bulk soil, implicating priming of denitrifying organisms as a possible mechanism for this effect. Furthermore, the earthworm feeding strategy may drive N 2 O emissions, as it determines access to fresh organic matter for denitrification. Here, we determined whether interactions between earthworm feeding strategy and the soil denitrifier community can predict N 2 O emissions from the soil. We set up a 90-day mesocosm experiment in which 15 N-labeled maize ( Zea mays L.) was either mixed in or applied on top of the soil in the presence or absence of the epigeic earthworm Lumbricus rubellus and/or the endogeic earthworm Aporrectodea caliginosa . We measured N 2 O fluxes and tested the bulk soil for denitrification enzyme activity and the abundance of 16S rRNA and denitrifier genes nirS and nosZ through real-time quantitative PCR. Compared to the control, L. rubellus increased denitrification enzyme activity and N 2 O emissions on days 21 and 90 (day 21, P = 0.034 and P = 0.002, respectively; day 90, P = 0.001 and P = 0.007, respectively), as well as cumulative N 2 O emissions (76%; P = 0.014). A. caliginosa activity led to a transient increase of N 2 O emissions on days 8 to 18 of the experiment. Abundance of nosZ was significantly increased (100%) on day 90 in the treatment mixture containing L. rubellus alone. We conclude that L. rubellus increased cumulative N 2 O emissions by affecting denitrifier community activity via incorporation of fresh residue into the soil and supplying a steady, labile carbon source.

Row\uffe2\uff80\uff90crop agriculture is a major source of nitrous oxide (N2O) globally, and results from recent field experiments suggest that significant decreases in N2O emissions may be possible by decreasing nitrogen (N) fertilizer inputs without affecting economic return from grain yield. We tested this hypothesis on five commercially farmed fields in Michigan, USA planted with corn in 2007 and 2008. Six rates of N fertilizer (0\uffe2\uff80\uff93225\uffe2\uff80\uff83kg\uffe2\uff80\uff83N\uffe2\uff80\uff83ha\uffe2\uff88\uff921) were broadcast and incorporated before planting, as per local practice. Across all sites and years, increases in N2O flux were best described by a nonlinear, exponentially increasing response to increasing N rate. N2O emission factors per unit of N applied ranged from 0.6% to 1.5% and increased with increasing N application across all sites and years, especially at N rates above those required for maximum crop yield. At the two N fertilizer rates above those recommended for maximum economic return (135\uffe2\uff80\uff83kg\uffe2\uff80\uff83N\uffe2\uff80\uff83ha\uffe2\uff88\uff921), average N2O fluxes were 43% (18\uffe2\uff80\uff83g\uffe2\uff80\uff83N2O\uffe2\uff80\uff93N\uffe2\uff80\uff83ha\uffe2\uff88\uff921\uffe2\uff80\uff83day\uffe2\uff88\uff921) and 115% (26\uffe2\uff80\uff83g\uffe2\uff80\uff83N2O\uffe2\uff80\uff93N\uffe2\uff80\uff83ha\uffe2\uff88\uff921\uffe2\uff80\uff83day\uffe2\uff88\uff921) higher than were fluxes at the recommended rate, respectively.

Emissions of the trace gas nitrous oxide (N2O) play an important role for the greenhouse effect and stratospheric ozone depletion, but the impacts of climate change on N2O fluxes and the underlying microbial drivers remain unclear. The aim of this study was to determine the effects of sustained climate change on field N2O fluxes and associated microbial enzymatic activities, microbial population abundance and community diversity in an extensively managed, upland grassland. We recorded N2O fluxes, nitrification and denitrification, microbial population size involved in these processes and community structure of nitrite reducers (nirK) in a grassland exposed for 4\uffc2\uffa0years to elevated atmospheric CO2 (+200\uffc2\uffa0ppm), elevated temperature (+3.5\uffc2\uffa0\uffc2\uffb0C) and reduction of summer precipitations (\uffe2\uff88\uff9220%) as part of a long\uffe2\uff80\uff90term, multifactor climate change experiment. Our results showed that both warming and simultaneous application of warming, summer drought and elevated CO2 had a positive effect on N2O fluxes, nitrification, N2O release by denitrification and the population size of N2O reducers and NH4 oxidizers. In situ N2O fluxes showed a stronger correlation with microbial population size under warmed conditions compared with the control site. Specific lineages of nirK denitrifier communities responded significantly to temperature. In addition, nirK community composition showed significant changes in response to drought. Path analysis explained more than 85% of in situ N2O fluxes variance by soil temperature, denitrification activity and specific denitrifying lineages. Overall, our study underlines that climate\uffe2\uff80\uff90induced changes in grassland N2O emissions reflect climate\uffe2\uff80\uff90induced changes in microbial community structure, which in turn modify microbial processes.

Nitrification is a ubiquitous microbially mediated process in the environment and an essential process in engineered systems such as wastewater and drinking water treatment plants. However, nitrification also contributes to fertilizer loss from agricultural environments, increasing the eutrophication of downstream aquatic ecosystems, and produces the greenhouse gas nitrous oxide. As ammonia-oxidizing bacteria are the most dominant ammonia-oxidizing microbes in fertilized agricultural soils, understanding their responses to a variety of environmental conditions is essential for curbing the negative environmental effects of nitrification. Notably, oxygen limitation has been reported to significantly increase nitric oxide and nitrous oxide production during nitrification. Here, we investigate the physiology of the best-characterized ammonia-oxidizing bacterium, Nitrosomonas europaea , growing under oxygen-limited conditions.

Abstract. Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4\u00a0months. A chamber closure time of 2\u2009min was sufficient for a reliable estimation of CO2 and CH4 fluxes (100\u2009% and 98.5\u2009% of fluxes were above minimum detectable flux \u2013 MDF, respectively). This closure time was generally not suitable for a reliable estimation of the low N2O fluxes in this ecosystem but was sufficient for detecting rare major peak events. A closure time of 25\u2009min was more appropriate for reliable estimation of most N2O fluxes (85.6\u2009% of measured fluxes are above MDF\u2009\u00b1\u20090.002\u2009nmol\u2009m\u22122\u2009s\u22121). Our study highlights the importance of adjusted closure time for each gas.

Freeze-thaw (FT) events in soils can cause a burst of nitrous oxide (N2O) and enhance N leaching during the spring-thaw event. We studied whether a soil amended with wood-derived (spruce chips) biochar (10 tonnes ha-1), produced at rather low temperatures (400-450\uffc2\uffb0C), could reduce the burst of N2O and the risk of N leaching from an agricultural soil after a FT event. A short-term laboratory experiment (4 weeks) was conducted with 24 vegetated (Phleum pratense) mesocosms (12 controls, 12 biochar-treated) that had spent a dormant season in the dark at 15\uffc2\uffb0C for two months after the growing season. N2O efflux to the atmosphere and ammonium (NH4+-N) and nitrate (NO3-N) in the percolated soil water were monitored before and after the FT event. N2O was monitored with the dark chamber method and analyzed using a gas chromatograph. We found that soil amended biochar can significantly diminish the burst of N2O after the soil FT event (by 61% just after FT event) and substantially reduce the risk of NO3-N and NH4+-N leaching from the agricultural soil. Compared to the control, the decrement in concentrations of NO3-N and NH4+-N in water percolated through the biochar amended soil in the mesocosms was 58% and 22%, respectively.

High rates of fertilizer applications potentially have significant environmental consequences, such as soil and water contamination and biodiversity loss. This study aimed to compare the use of biofertilizers and inorganic fertilizers in a broccoli crop to determine their impact on soil microorganism abundance, microbial community structure, functional gene diversity, yield, and greenhouse gas emissions. Four different fertilization treatments were designed: (i) inorganic fertilizers applied at a rate to cover the nutritional demands of the crop (F100); (ii) 50% of the rate of inorganic fertilizers added in F100 (F50); (iii) F50 + the application of a formulation of various bacteria (BA); and (iv) F50 + the application of a formulation of bacteria and non-mycorrhizal fungi (BA + FU). The results showed that reduced fertilization and the addition of both biofertilizer products had no significant effect on soil nutrients, microbial population, microbial activity, or yield when compared to conventional inorganic fertilization. Thus, microbial inoculants were ineffective in enhancing soil microbial abundance and activity, and there were no changes in GHG emissions or crop yields. Nonetheless, crop yield was positively related to total soil N, microbial activity, and CO2 emissions, confirming the positive effect of soil biodiversity on production. The application of biofertilizers can help reduce mineral fertilization in a broccoli crop with no negative effect on yield.

Abstract. Nitrous oxide emissions from a network of agricultural experiments in Europe and Zimbabwe were used to explore the relative importance of site and management controls of emissions. At each site, a selection of management interventions were compared within replicated experimental designs in plot based experiments. Arable experiments were conducted at Beano in Italy, El Encin in Spain, Foulum in Denmark, Log\uffc3\uffa5rden in Sweden, Maulde in Belgium, Paulinenaue in Germany, Harare in Zimbabwe and Tulloch in the UK. Grassland experiments were conducted at Crichton, Nafferton and Peaknaze in the UK, G\uffc3\uffb6d\uffc3\uffb6ll\uffc3\uffb6 in Hungary, Rzecin in Poland, Zarnekow in Germany and Theix in France. Nitrous oxide emissions were measured at each site over a period of at least two years using static chambers. Emissions varied widely between sites and as a result of manipulation treatments. Average site emissions (throughout the study period) varied between 0.04 and 21.21 kg N2O-N ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, with the largest fluxes and variability associated with the grassland sites. Total nitrogen addition was found to be the single most important determinant of emissions, accounting for 15% of the variance (using linear regression) in the data from the arable sites (p < 0.0001), and 77% in the grassland sites. The annual emissions from arable sites were significantly greater than those that would be predicted by IPCC default emission factors. Variability in N2O within sites that occurred as a result of manipulation treatments was greater than that resulting from site to site and year to year variation, highlighting the importance of management interventions in contributing to greenhouse gas mitigation.

Abstract. Adopting soil and crop management practices that conserve or enhance soil structure is critical for supporting the sustainable adaptation of agriculture to climate change, as it should help maintain agricultural production in the face of increasing drought or water excess without impairing environmental quality. In this paper, we evaluate the evidence for this assertion by synthesizing the results of 34 published meta-analyses of the effects of such practices on soil physical and hydraulic properties relevant for climate change adaptation in European agriculture. We also review an additional 127 meta-analyses that investigated synergies and trade-offs or help to explain the effects of soil and crop management in terms of the underlying processes and mechanisms. Finally, we identify how responses to alternative soil\u2013crop management systems vary under contrasting agro-environmental conditions across Europe. This information may help practitioners and policymakers to draw context-specific conclusions concerning the efficacy of management practices as climate adaptation tools. Our synthesis demonstrates that organic soil amendments and the adoption of practices that maintain \u201ccontinuous living cover\u201d result in significant benefits for the water regulation function of soils, mostly arising from the additional carbon inputs to soil and the stimulation of biological processes. These effects are clearly related to improved soil aggregation and enhanced bio-porosity, both of which reduce surface runoff and increase infiltration. One potentially negative consequence of these systems is a reduction in soil water storage and groundwater recharge, which may be problematic in dry climates. Some important synergies are reductions in nitrate leaching to groundwater and greenhouse gas emissions for nonleguminous cover crop systems. The benefits of reducing tillage intensity appear much less clear-cut. Increases in soil bulk density due to traffic compaction are commonly reported. However, biological activity is enhanced under reduced tillage intensity, which should improve soil structure and infiltration capacity and reduce surface runoff and the losses of agro-chemicals to surface water. However, the evidence for these beneficial effects is inconclusive, while significant trade-offs include yield penalties and increases in greenhouse gas emissions and the risks of leaching of pesticides and nitrate. Our synthesis also highlights important knowledge gaps on the effects of management practices on root growth and transpiration. Thus, conclusions related to the impacts of management on the crop water supply and other water regulation functions are necessarily based on inferences derived from proxy variables. Based on these knowledge gaps, we outlined several key avenues for future research on this topic.
