Conservation agriculture is often assumed to reduce soil N2O emissions. Yet, studies analyzing the specific effect of conservation agriculture practices on N2O emissions give contradictory results. Herein, we synthesized a comprehensive database on the three main conservation agriculture practices (cover crops, diversified crop rotations, and no-till and/or reduced tillage (NT/RT)) to elucidate the role of conservation practices on N2O emissions. Further, we used a random meta-forest approach to identify the most important predictors of the effects of these practices on soil N2O emissions. Averaged across all comparisons, NT/RT significantly decreased soil N2O emissions by 11% (95% CI: \uffe2\uff80\uff9319 to \uffe2\uff80\uff931%) compared to conventional tillage. The reductions due to NT/RT were more commonly observed in humid climates and in soils with an initial carbon content < 20 g kg\uffe2\uff80\uff931. The implementation of cover crops and diversified crop rotations led to variable effects on soil N2O emissions. Cover crops were more likely to reduce soil N2O emissions at neutral soil pH, and in soils with intermediate carbon (~20 g kg\uffe2\uff80\uff931) and nitrogen (~3 g kg\uffe2\uff80\uff931) contents. Diversified crop rotations tended to increase soil N2O emissions in temperate regions and neutral to alkaline soils. Our results provide a comprehensive predictive framework to understand the conditions in which the adoption of various conservation agriculture practices can contribute to climate change mitigation. Combining these results with a similar mechanistic understanding of conservation agriculture impacts on ecosystem services and crop production will pave the way for a wider adoption globally of these management practices.\u22121 are available in the North Chain Plain (NCP), which requires managing and thus can be properly used in irrigated agriculture to relieve the increasing pressure on fresh water in this region for supplementary irrigation. Field experiments were conducted to investigate the soil salt accumulation, responses, and yield simulation of winter wheat to the alternate irrigation strategies during 2017\u20132019. Five irrigation strategies included rain-fed cultivation (NI), fresh and saline water irrigation (FS), fresh water irrigation (FF), saline water irrigation (SS), and saline and fresh water irrigation (SF) during the growth stages. Irrigation with saline water increased soil salinity level and could be balanced annually; however, the leaf gas exchange of winter wheat was almost not significantly affected. The salinity caused by saline water irrigation negatively influenced the vegetative growth. The grain yield was increased by 24% and 32% under the FS and SF treatments compared to NI, while a minor reduction by 12% and 5% in yield under these treatments was recorded compared with the FF treatment. The SALTMED model was calibrated and validated to predict yield, and the high value of the R2 reflected a good agreement between modeled and observed values, indicating that the SALTMED model was able to simulate grain yield under the alternate irrigation strategies in the regional climate condition. Supplementary irrigation using saline water at the stem elongation stage and fresh water at the flowering stage is a practical solution to achieve comparable yields with low risk of salt accumulation for winter wheat particularly in the NCP.", "keywords": ["2.

Microplastics are increasingly recognized as a factor of global change. By altering soil inherent properties and processes, ripple-on effects on plants and their symbionts can be expected. Additionally, interactions with other factors of global change, such as drought, can influence the effect of microplastics. We designed a greenhouse study to examine effects of polyester microfibers, arbuscular mycorrhizal (AM) fungi and drought on plant, microbial and soil responses. We found that polyester microfibers increased the aboveground biomass of Allium cepa under well-watered and drought conditions, but under drought conditions the AM fungal-only treatment reached the highest biomass. Colonization with AM fungi increased under microfiber contamination, however, plant biomass did not increase when both AM fungi and fibers were present. The mean weight diameter of soil aggregates increased with AM fungal inoculation overall but decreased when the system was contaminated with microfibers or drought stressed. Our study adds additional support to the mounting evidence that microplastic fibers in soil can affect the plant-soil system by promoting plant growth, and favoring key root symbionts, AM fungi. Although soil aggregation is usually positively influenced by plant roots and AM fungi, and microplastic promotes both, our results show that plastic still had a negative effect on soil aggregates. Even though there are concerns that microplastic might interact with other factors of global change, our study revealed no such effect for drought.

Tire particles (TPs) are a major source of microplastic on land, and considering their chemical composition, they represent a potential hazard for the terrestrial environment. We studied the effects of TPs at environmentally relevant concentrations along a wide concentration gradient (0\uffe2\uff80\uff93160 mg g\uffe2\uff88\uff921) and tested the effects on plant growth, soil pH and the key ecosystem process of litter decomposition and soil respiration. The addition of TPs negatively affected shoot and root growth already at low concentrations. Tea litter decomposition slightly increased with lower additions of TPs but decreased later on. Soil pH increased until a TP concentration of 80 mg g\uffe2\uff88\uff921 and leveled off afterwards. Soil respiration clearly increased with increasing concentration of added TPs. Plant growth was likely reduced with starting contamination and stopped when contamination reached a certain level in the soil. The presence of TPs altered a number of biogeochemical soil parameters that can have further effects on plant performance. Considering the quantities of yearly produced TPs, their persistence, and toxic potential, we assume that these particles will eventually have a significant impact on terrestrial ecosystems.

Mangroves are one of the most ecologically sensitive ecosystems to global climate change, which have cascading impacts on soil carbon (C), nitrogen (N) and phosphorus (P) cycling. Moreover, mangroves are experiencing increasing N and P loadings and reduced oxygen availability due to intensified climate change and human activities. However, both direct and interactive effects of these perturbations on microbially mediated soil C, N and P cycling are poorly understood. Here, we simultaneously investigated the effects of N and P loadings and reduced oxygen on microbial biomass, microbial respiration, and extracellular enzyme activities (EEAs) in mangrove soils. We calculated the microbial metabolic quotient (qCO2), which is regarded as a useful inverse metric of microbial C use efficiency (CUE). Our results show that reduced oxygen significantly increases both qCO2 and microbial specific EEAs (enzyme activity per unit of microbial biomass) for C-, N- and P-acquisition regardless of N or P loadings. Furthermore, we found that qCO2 positively correlated with microbial specific EEAs under reduced oxygen, whereas no clear relationship was detected under ambient oxygen. These results suggest that reduced oxygen increases microbial specific EEAs at the expense of increasing microbial respiration per unit biomass, indicating higher energy cost per unit enzyme production.", "keywords": ["mangrove", "nutrient acquisition", "microbial respiration", "nutrient addition", "13.

Therefore, land-use systems that increase the soil organic matter (SOM) pool and stabilize soil organic carbon (SOC) need to be implemented. Agroforestry systems have the potential to sequester atmospheric carbon (C) in trees and soil while maintaining sustainable productivity. The potential to sequester C in agroforestry systems in tropical and temperate regions is promising, but little information is available to date. The objective of this paper is to give an overview of the history of agroforestry and to outline differences in management practices between tropical and temperate systems. This review focuses on C inputs, SOC pools and SOC stabilization with highlights from Costa Rican and Canadian systems, and their role in C sequestration and trading. The potential to sequester C in aboveground components in agroforestry systems is estimated to be 2.1 \u00d7 10 9 Mg C year \u22121 in tropical and 1.9 \u00d7 10 9 Mg C year \u22121 in temperate biomes. However, the type of agroforestry systems and their capacity to sequester C vary globally. For example, alley cropping is an agroforestry practice where trees are integrated with crops, therefore storing C in the woody components of the trees and in the soil, with a continual addition of organic material from tree prunings and crop residues. Studies from Costa Rica have shown that a 10-year-old system with E. poeppigianasequestered C at a rate of 0.4 Mg C ha \u22121 year \u22121 in coarse roots and 0.3 Mg C ha \u22121 year \u22121 in tree trunks. Tree branches and leaves are added to the soil as mulch, contributing 1.4 Mg C ha \u22121 year \u22121 in addition to 3.0 Mg ha \u22121 year \u22121 from crop residues. This resulted in an annual increase of the SOC pool by 0.6 Mg ha \u22121 year \u22121 . Despite the two crop rotations in tropical agroforests, C input from crop residues is similar between the two biomes. The total organic matter input, however, is still greater in tropical systems due to the larger addition from tree prunings. This greater input does not necessarily increase the SOC pool significantly when compared to a temperate system of similar age as a result of faster turnover rates of the SOM pool. \u00a9 2004 Elsevier B.V.

The highest flux was 131.56 \u03bcg N2O\ue5f8N m\u22122 h\u22121, measured during the fifteenth week after transplanting and the lowest was \u221217.56 \u03bcg N2O\ue5f8N m\u22122 h\u22121, measured in the twelfth week. The mean flux was 22.65 \u00b1 20.15 \u03bcg N2O\ue5f8N m\u22122 h\u22121. Submerging the paddies by continuously flooding the field caused significant reduction in N2O flux compared with the field irrigated intermittently. This suggests that aerobic-anaerobic cycling triggers interchangeable nitrification of ammonia and denitrification of nitrate, enhancing the total N2O emissions. The effects of different types of urea on N2O fluxes were further examined using a statistical profile analysis at each growing stage. During the reproductive stage, the N2O flux from plots with the submerged tablet urea in the denitrifying zone was indicated to be significantly larger compared with plots fertilised using granule urea, which was spread over the surface occupying the nitrifying aerobic layer. The two different rice varieties having different morphological characteristics and planted during April\u2013August 1995 showed no significance difference in the mean seasonal N2O flux in all treatments. However, when comparisons were made for different growing stages, the flux was indicated to be significantly different during the reproductive stage (week 6\u201311). This was shown for both fertiliser and irrigation applications. The results suggest that to control N2O emission, field management should consider the irrigation and fertiliser application schedule and combination. Based on the varieties' nitrogen uptake efficiency ranging from 35% (IR-64) to 45% (Cisadane), both varieties could have resulted insignificantly different flux but since they have different growing period the total seasonal emission differs substantially.", "keywords": ["2.

Local researches are necessary to gain information on buffer performance, with particular emphasis on narrow buffers. The effect of a 6\u00a0m buffer strip (BS) in reducing runoff, suspended solids and nutrients from a field growing maize, winter wheat and soybean was assessed in a field experiment conducted in North-East Italy during 1998\u20132001. The BS was composed of two rows of regularly alternating trees (Platanus hybrida Brot.) and shrubs (Viburnum opulus L.), with grass (Festuca arundinacea L.) in the inter-rows. The BS reduced total runoff by 78% compared to no-BS, in which cumulative runoff depth was 231\u00a0mm over 4 years. With no-BS runoff appeared to be influenced mostly by total rainfall, while with BS maximum rainfall intensity was more important. The filtering effect of the BS reduced total suspended solids (TSS), particularly after the second year, when the median yearly concentrations ranged from 0.28 to 0.99\u00a0mg\u00a0L\u22121 and were smaller than 0.14\u00a0mg\u00a0L\u22121, with no-BS and with BS respectively. The combination of lower concentrations and runoff volumes significantly reduced TSS losses from 6.9 to 0.4\u00a0t\u00a0ha\u22121 over the entire period. A tendency to increased concentrations of all forms of N (total, nitrate and ammonium) while passing through the BS was observed, but total N losses were reduced from 17.3 to 4.5\u00a0kg\u00a0ha\u22121 in terms of mass balance. On the contrary, P concentrations were unmodified (soluble P), or lowered (total P) by the BS, reducing total losses by about 80%. The effect on total P, composed mainly of sediment-bound forms, was related to particulate settling when passing through the BS. A numerical index (Eutrophic Load Index), integrating water quality and runoff volumes, was created to evaluate the eutrophication risk of runoff with or without the BS. It showed that the BS effect was mostly due to a reduction of runoff volumes rather than improving the overall water quality.", "keywords": ["2. Zero hunger", "13. Climate action", "14.

In the US, over 50 billion liters of ethanol produced in 2010 is mandated to increase to 136 billion liters by 2022. Globally, approximately 33.3\u00a0million\u00a0ha (Mha) of land under production of biofuels in 2008 may increase to as much as 82\u00a0Mha by 2020. Whereas data on the energy efficiency and GHG balances for biofuels are available, information on agronomic and ecological consequences of large-scale production of bioenergy crops is sparse. Thus, this paper describes the potential effects that bioenergy production may have on ecosystems. Conversion of land to biofuel crops may have significant impacts on ecosystem services such soil and water quality, GHG emissions, wildlife habitat, net primary productivity, and biological control, and plant diversity at both the landscape and the regional levels. Production of exotic species for feedstock may increase the risk of escape from agriculture and invasion into natural ecosystems. Several feedstocks, while suitable on the basis of energy and GHG assessments, may have negative ecosystem impacts (i.e., increased N export in the Gulf of Mexico). Bioenergy feedstock may compete with food crops for land, water, and nutrient resources, resulting in higher prices for food as well as potential increases in malnutrition and food insecurity. Biofuels can be a sustainable and renewable source of energy, but assessments must include ecological impacts, economic costs, and energetic efficiencies.", "keywords": ["2. Zero hunger", "13.

Four soil pretreatment procedures were compared: (1) air-dried, capillary wetted (AD-CW), (2) air-dried, tension wetted (AD-TW), (3) air-dried, slaked (AD-SL), and (4) field-moist, capillary wetted (FM-CW). Air-drying soils resulted in a greater quantity of aggregates in the coarser fractions (> 250 \u03bcm), as compared to field-moist soils, with a consequent reduction in the finer fractions (> 250 \u03bcm). Differences between methods of wetting air-dried soils were more pronounced for the clayey soils where both AD-CW and AD-SL resulted in a greater proportion (22\u201324%) of the soil mass in the finer fractions (> 250 \u03bcm), as compared with AD-TW (4.5%). The FM-CW procedure had the lowest coefficients of variation (2\u20138%) for repeated measurements. The AD-CW and FM-CW procedures were also used to compare the effects of cropping systems [conventional tillage (CT) (soybean/fallow), CT (sorghum/fallow), and no-tillage (NT) (sorghum/clover)], erosion classes (slight, moderate, and severe) and irrigation (drip-irrigated or nonirrigated) on water-stable aggregates (> 250 \u03bcm). In general, water-stable aggregates increased with decreasing intensity of cultivation, increasing severity of erosion and irrigation. Air-drying soils resulted in less differences in water-stable aggregates between treatments, but provided more detailed information on the interactive effects of cropping system and irrigation as compared with the field-moist condition. Similar differences were observed in aggregate disruption rates that were calculated from the aggregates recovered after wet-sieving for intervals of 1\u201332 min. Although water-stable aggregates were lower by FM-CW, this procedure showed greater separation of treatment means (e.g. erosion classes) than the AD-CW procedure. We also compared single versus multiple-sieve techniques for describing the effects of pretreatment conditions on aggregate distributions. For the clayey Pacolet soil, a fine fractionation into eleven aggregate size classes revealed the greatest differences (P > 0.05) between the FM-CW and AD-CW procedures, while a coarse fractionation into macro- (> 250 \u03bcm) and micro- (> 250 \u03bcm) aggregates showed no differences. However, for the sandy Hiwassee soil differences in aggregate distributions between the FM-CW and AD-CW procedures were found at most levels of fractionation, but were not detected by comparing the calculated mean weighted diameters. In general, our findings emphasize the value of comparing soil specific responses to different pretreatment conditions, particularly those that compare the distributions of aggregates among size classes, as a means for describing environmental influences on soil structure.", "keywords": ["2.

Short-term (10-year) management effects on SOC and TN dynamics are often complex and variable. Three experiments were conducted to evaluate short-term tillage and cropping system effects on SOC and TN within the 0\u201030 cm soil depth across Iowa. The first experiment with no-tillage and chisel plowing treatments was established in 1994 on Clarion-Nicollet-Webster (CNW), GalvaPrimghar-Sac (GPS), Kenyon-Floyd-Clyde (KFC), Marshall (M), and Otley-Mahaska-Taintor (OMT) soil associations under a corn (Zea mays L.)\u2010soybean (Glycine max (L.) Merr.) rotation. The second experiment with no-tillage, strip-tillage, chisel plowing, deep ripping, and moldboard plowing treatments was initiated in 1998 on the CNW soil association in a corn\u2010soybean rotation. The third experiment consisting of smooth bromegrass (Bromus inermis Leyss.), switchgrass (Panicum virgatum L.) and corn\u2010soybean\u2010alfalfa (Medicago sativa L.) treatments was established in 1991 on Monona-Ida-Hamburg (MIH) soil association under no-tillage management. Short-term tillage effects on SOC and TN occurred primarily at the 0\u201015 cm soil depth. Tillage effects did not vary significantly with soil association. No-tillage resulted in greater SOC and TN contents than chisel plowing at the end of 7 years of tillage practices averaged over the CNW, GPS, KFC, M, and OMT soil associations. The increase in SOC and TN with no-tillage was not related to SOC and TN stratification in the soil profile or annual C and N inputs from crop residue, but most likely due to decreased mineralization rate of soil organic matter. However, tillage effects on SOC and TN were negligible at the end of only 3 years of tillage practices on the CNW soil association. Smooth bromegrass and switchgrass systems resulted in greater SOC and TN contents at both 0\u201015 cm and 15\u201030 cm soil depths than a corn\u2013soybean\u2013 alfalfa rotation after 10 years of management on the MIH soil association. Smooth bromegrass and switchgrass systems increased SOC by 2.3 and 1.2 Mg ha 1 yr 1 at the 0\u201015 cm soil depth, respectively. We conclude from these short-term experiments that reducing tillage intensity and increasing crop diversity to include perennial grasses could be effective in improving C and N sequestration in Midwest soils. # 2004 Elsevier B.V.

Soil microbial biomass, activities of alkaline phosphatases, \u03b2-glucosidases and proteases, and phospholipid fatty acid profiles were evaluated in soils from three different fertiliser treatments (inorganic, NPK; farmyard manure, FYM; without, CON) at two sites (Bad Lauchstadt, Germany and Keszthely, Hungary). The results showed that Corg and Nt concentrations were significantly higher in the FYM plots compared to the NPK amendments or CON. Furthermore, increases were observed in the Cmic and the enzyme activities of FYM-fertilised treatments in the soil at Bad Lauchstadt. NPK fertilisation significantly decreased Cmic in the soil at Keszthely, whereas FYM increased the activity of \u03b2-glucosidases. Ecophysiological parameters (Cmic-to-Corg and qCO2) revealed a clear climatic influence on edaphic properties. The profiles of 28 phospholipid fatty acids (PLFAs) were used to assess whether observed changes in functional microbial parameters were accompanied by changes in the composition of the microbial communities after FYM and NPK amendments. The results of principal component analyses indicate that the communities of the autochthonous microflora differed between the two sites and three treatments. Bacteria, particularly Gram-negative bacteria and eukaryotes were responsible for these differences. The results support the hypothesis that fertilisation in general and its forms (organic versus inorganic) affect important functional and structural soil microbial properties.

Even in areas used only minimally for grazing activities (I), a serious increase (doubling) in soil hardness was apparent in the upper soil layer. A continual decrease in organic matter in the surface soil can be correlated directly to soil compaction. The content of organic matter in soil of degree IV amounts to only a third of the organic matter found in non-grazed areas. This decrease can be attributed partly to the poor living conditions for soil organisms in compacted soils, but also to a significant reduction in litter. This is because intensive grazing causes reduced vegetation cover leading to litter being blown away by wind or washed away by heavy rainfall. Thus in level III hardly any plant litter remained to be incorporated into the soil as humus. Likewise root density also suffered its largest decrease in areas with a grazing intensity level III. With regard to the content of nitrogen and phosphorous (total and available) hardly any difference between soils of grazing intensity 0 and I was observed, whereas a noticeable decrease was apparent between levels I and II. Available Potassium was similar for all grazing levels. The pH-value of the soil solution is not significantly affected by grazing.

External influences such as forest clearance and soil management affect biological indicators making them useful to point out whether the land use strategy is sustainable. Accordingly, the aim of this work was to assess the utility of some soil chemical and microbiological properties and 16S rDNA diversity in bacteria domain and their significance as soil-quality indicators in different land use systems in southern Brazil, Parana State. Nine sites with soil originated from basalt (Rhodic Ferralsol), previously covered with the Atlantic native forest were evaluated: a native forest tract as reference; three sites artificially reforested with native species, but with understory differently managed; secondary forest naturally regenerated from abandoned pasture; artificially reforested with eucalyptus; two wheat-cropped sites at differing vegetative stages; one site in fallow. Twenty-four chemical and microbiological properties and their derivatives were assessed, in addition to molecular diversity of bacteria domain based on denaturating gradient gel electrophoresis (DGGE) analysis. Amongst all variables, the most dissimilar along the sites were total organic C, microbial biomass C and N, and ammonification rate. Total organic C was highest in the native forest, followed by secondary forest, eucalyptus and the artificially reforested sites; the wheat-cropped and fallow sites produced the lowest values. This trend was also observed for ammonification rate, which was closely correlated to organic C. Microbial biomass C and N were also higher in the reforested sites, whereas for microbial N biomass, the eucalyptus site resembled to the wheat-cropped and fallow sites. The DGGE analysis revealed that the fallow, eucalyptus and wheat-cropped sites had less bacterial diversity. All the sites reforested with native species grouped with the native forest, while the eucalyptus, fallow and wheat-cropped sites formed separate clusters. A similar clustering pattern was observed when all chemical and microbiological properties were considered in a grouping analysis. The results for reforestation employing native species tended to be similar to those of the stable native forest, while the use of an exotic species (eucalyptus) tended to be similar to those of the cropped sites. In addition, the fallow site showed general unfavorable trends in microbiological indicators and less bacterial diversity, suggesting that such soil management is not sustainable at least in subtropical areas. In this case, would be preferable provide the soil with vegetal covering that increase the organic C inputs and consequently microbial diversity and activity.", "keywords": ["2. Zero hunger", "13.

Plant and soil C and N content and isotopic ratios, soil microbial biomass C, and potential C mineralization were measured in areas of the southern Caldenal region of central Argentina with known histories of fire and grazing. Results support the hypothesis that fire reduces rates of N cycling via intraspecific increases in plant tissue C/N. Contrary to our first hypothesis, grazing also reduced plant tissue N. Fire and grazing effects on plant tissue chemistry resulted primarily from changes in dynamics of soil inorganic N. These changes were due to intraspecific changes in plant tissue chemistry, which was in agreement with our second hypothesis. Potential C mineralization experiments revealed little difference between treatments in pool sizes and mean residence times of labile soil organic carbon.

In water-limited systems such as those of the Mediterranean, carbon allocation patterns strongly favour belowground accumulation, especially in large subterranean structures called lignotubers. The resilience of these forests depends largely on the replenishment rate of these carbon reserves after disturbances. An experimental thinning, with two intensities (removal of 40% and 80% of basal area), was performed in 1992 in a holm oak forest at the Prades Experimental Complex of Catchments (NE Spain). In 2002, a second thinning was carried out in subplots within the former experimental 0.5 ha plots. Samples from the lignotubers of holm oak trees were analyzed for starch, and both mobile and immobile chemical components, in order to assess the resilience of holm oaks to repeated disturbances. Our results show that after 10 years, starch stocks in the lignotubers have only recovered to half their former values. Removing 40% of the basal area instead of 80% is suggested to be the better managing option for this kind of forests.", "keywords": ["0106 biological sciences", "13.

We simulated drought within the long-term EVENT experimental site in the Ecological-Botanical Garden, University of Bayreuth to understand how Arrhenatherum elatius (L.) responds to water stress when grown in three different plant assemblages. The set up consisted of five replications for each factorial combination of drought and plant assemblages differing in functional diversity. Leaf water potential (\u03a8 L ), leaf gas exchange, natural \u03b4 13 C, plant biomass and cover were measured. Imposed drought had different effects on A.\u00a0elatius , depending on plant assemblage composition. Severe water stress was however, avoided by slowing down the rate of decline in \u03a8 L, and this response was modified by community composition. High \u03a8 L was associated with high stomatal conductance and leaf photosynthesis. Biomass production of A.\u00a0elatius increased due to drought stress only in the least diverse assemblage, likely due to increased tillering and competitive advantage against neighbors in the drought-treated plants. Our results indicate that beneficial traits among plant species in a community may be responsible for the enhanced capacity to survive drought stress.

We compared fallows of Acacia crassicarpa, A. julifera, A. leptocarpa, Leucaena pallida and Senna siamea, with traditional bush fallow and continuous sole maize (Zea mays L.). The aim of the study was to analyze the effectiveness offallow types in terms of N, Pand K use by maize. Trees were intercropped with maize for the first 3 years. After 5 years, trees were harvested, wood components were removed, and leaves, twigs and grasses were incorporated into the soil. Factorial N,P,Ktrialswere carriedoutwithmaizegrown afterthefallowtypes. Parameters studiedweregrainyield,uptakeof N,PandK,and nutrient use efficiency. The effects offertiliser were much stronger than the effects offallow types. Therewas no clear effect of tree fallows on nutrient use efficiency of the following maize. Non-fertilized maize yielded more after acacia than after the other trees and natural fallow. Upon fertiliser application the influences of fallow types became weaker. Fertiliser N improved maize yields more than fertiliser P, and there was a positive NP interaction. Fertilizer K did not bring about clear effects. N recovery efficiency was improved by the application of P and vice versa. When fertilisers were applied, differences in average maize grain yields between tree fallows and natural fallow varied from 300 kg ha 1 (for A. julifera) to minus 250 kg ha 1 (for S. siamea). A yield increase of 300 kg maize grain could also be obtained by application of 10 kg fertiliser N or 8 kg fertiliser P. The best fallow type for soil fertility improvement was Acacia juliferasuggesting that this acacia is mining the soil for P and K.

The responses of natural ecosystems to these changes are focus for research, due to the potential feedbacks to the climate. We here present results from a field experiment in which the effects of these three climate change factors are investigated solely and in all combinations at a temperate heath dominated by heather (Calluna vulgaris) and wavy hair-grass (Deschampsia flexuosa). Climate induced increases in plant production may increase plant root exudation of dissolved organic compounds such as amino acids, and the release of amino acids during decomposition of organic matter. Such free amino acids in soil serve as substrates for soil microorganisms and are also acquired as nutrients directly by plants. We investigated the magnitude of the response to the potential climate change treatments on uptake of organic nitrogen in an in situ pulse labelling experiment with 15N13C2-labelled glycine (amino acid) injected into the soil. In situ root nitrogen acquisition by grasses responded significantly to the climate change treatments, with larger 15N uptake in response to warming and elevated CO2 but not additively when the treatments were combined. Also, a larger grass leaf biomass in the combined T and CO2 treatment than in individual treatments suggest that responses to combined climate change factors cannot be predicted from the responses to single factors treatments. The soil microbes were superior to plants in the short-term competition for the added glycine, as indicated by an 18 times larger 15N recovery in the microbial biomass compared to the plant biomass. The soil microbes acquired glycine largely as an intact compound (87%), with no effects of the multi factorial climate change treatment through one year.", "keywords": ["2. Zero hunger", "13.

If it is to be truly sustainable, it must maintain levels of soil fertility sufficient for economic crop production in the long-term, whilst also protecting the environment. This paper presents results comparing soils managed organically for at least 15 years, with soils under conventional management, on four arable farms in England. There were no significant differences in total soil organic matter, total nitrogen or C:N ratio between the conventionally and organically managed soils. However, concentrations of extractable potassium and phosphorus were significantly lower in soils managed organically. The largest difference between the conventional and organic fields in potassium concentration was on the oldest organic farm. These results support the argument that organic mixed arable systems are mining reserves of potassium and phosphorus, built up during conventional management, and that changes to organic management practices to increase inputs of potassium and phosphorus are required, if long-term declines in soil fertility, and thus, yields are to be avoided.", "keywords": ["2.
