The processes that are affected by land use and management are generally understood, but uncertainties in projections are high. In this paper, we investigate the long-term effects of chronosequential land use change from grassland to cropland and vice versa on soil carbon stock dynamics in four fields on a Swedish farm. Between 1850 and 1920, three of the fields were converted from grassland into cropland, and one was converted back to grassland in 1971. The fourth (control) field is a grassland that has never been ploughed. In 1937, the four fields were sampled at 111 points in a regular grid (25 or 50\u00a0m) and the dried soil samples were stored at our Department. In 1971 and 2002, the original grid points were revisited and re-sampled. Land use changes affected the soil C stock significantly. In 1937, carbon stocks were significantly smaller in the arable fields than in the grassland soil. In the field that was converted from arable back to grassland, soil C increased significantly at an average rate of about 0.4\u00a0Mg ha\u22121\u00a0year\u22121. A soil C balance model (ICBM) driven by standard meteorological data and soil carbon input estimated from yield records described soil carbon dynamics reasonably well, although the range of simulated relative changes in C stocks between 1937 and 2002 in the four fields (from \u22127.4 to +8.8%) was narrower than those measured (from \u221219.5 to +16.5%). There are only few long-term studies in Northern Europe available for quantifying the effect of land use change on soil carbon stocks and the results presented here are therefore useful for improving predictions of changes in soil carbon driven by land use change.", "keywords": ["Soil science", "2.

Most of the chemical parameters were influenced by the type of tillage practice. ZZ increased the soil organic carbon (SOC) content in the upper soil layer from 6.8 to 7.5 mg g\u22121 soil. Similarly available N was increased by 6.1% in ZZ over CC. Under zero tillage soil generally had higher P and K content than under other tillage practices. Soil carbohydrate content was also increased from 3.1 to 4.9 mg g\u22121 and dehydrogenase activity was also increased significantly under continuous zero-tillage practice. Alkaline phosphatase, protease, and cellulase were most sensitive to changes due to tillage management. Alkaline phosphatase and protease activity was greater (by 9.3\u201348.1%) in the zero-tillage system over conventional practice. In contrast, cellulase activity was more (by 31.3\u201374.6%) in conventional practice than other management practices.

We conducted a study to evaluate the effect of three different irrigation intensities on soil N2O and CO2 fluxes and to determine if irrigation management can be used to mitigate N2O emissions from irrigated cotton on black vertisols in South-Eastern Queensland, Australia. Fluxes were measured over the entire 2009/2010 cotton growing season with a fully automated chamber system that measured emissions on a sub-daily basis. Irrigation intensity had a significant effect on CO2 emission. More frequent irrigation stimulated soil respiration and seasonal CO2 fluxes ranged from 2.7 to 4.1 Mg-C ha\u22121 for the treatments with the lowest and highest irrigation frequency, respectively. N2O emission happened episodic with highest emissions when heavy rainfall or irrigation coincided with elevated soil mineral N levels and seasonal emissions ranged from 0.80 to 1.07 kg N2O-N ha\u22121 for the different treatments. Emission factors (EF = proportion of N fertilizer emitted as N2O) over the cotton cropping season, uncorrected for background emissions, ranged from 0.40 to 0.53 % of total N applied for the different treatments. There was no significant effect of the different irrigation treatments on soil N2O fluxes because highest emission happened in all treatments following heavy rainfall caused by a series of summer thunderstorms which overrode the effect of the irrigation treatment. However, higher irrigation intensity increased the cotton yield and therefore reduced the N2O intensity (N2O emission per lint yield) of this cropping system. Our data suggest that there is only limited scope to reduce absolute N2O emissions by different irrigation intensities in irrigated cotton systems with summer dominated rainfall. However, the significant impact of the irrigation treatments on the N2O intensity clearly shows that irrigation can easily be used to optimize the N2O intensity of such a system.", "keywords": ["2.

Pomel) is a parasitic plant, which causes severe yield losses in major crops worldwide. Because of its broad host range, including numerous non-parasitic weed species, the persistence of its seeds in the soil, and the poor efficiency of available management techniques, broomrape management is complex. The objective of the present paper was to develop a broomrape-dynamics model to support the design of management strategies combining multiple techniques aiming at long-term control of broomrape. Towards this goal, we developed a simulation model with formalisms and parameters based on data from our own experiments and the literature. This model called  PheraSys  combines 1) a demographic submodel to predict broomrape seed bank dynamics, 2) a trophic-relationships submodel to predict the effect of parasitism on crops and weeds, and 3) a submodel of weed dynamics in agroecosystems to predict the growth of crops and weeds from cropping techniques and pedoclimate. Thanks to an individual representation of each host plant,  PheraSys  is able to simulate complex heterogeneous canopies. This model can be used as a tool to test management strategies including crop mixtures and relying on biological regulations by weeds.", "keywords": ["[SDV.SA.AGRO] Life Sciences [q-bio]/Agricultural sciences/Agronomy", "0106 biological sciences", "2.

However, this benefit is lost quickly during the cropping phase. The objective of this study was to evaluate SOC dynamics of an improved fallow-maize rotation under no-tillage (NT) and conventional tillage (CT) from time of fallow termination, through the next two cropping seasons. The treatments studied were improved fallows of Acacia angustissima (A. angustissima) and Sesbania sesban (S. sesban), natural fallow and continuous maize. Our hypothesis is that fallowing maintained higher SOC and lower soil bulk densities through the cropping phase when compared with continuous maize system and that NT maintained higher SOC when compared with CT. Soil organic carbon was significantly greater under fallows than under continuous maize from fallow termination to the end of the second cropping season. Soil organic carbon for the 0\u20135 cm depths was 11.0, 10.0, 9.4 and 6.6 g kg\u22121 for A. angustissima, S. sesban, natural fallow and continuous maize, respectively at fallow termination. After two cropping seasons SOC for the same depth was 8.0, 7.0, 6.1, 5.9 g kg\u22121 under CT and 9.1, 9.0, 8.0, 6.0 g kg\u22121 under NT for A. angustissima, S. sesban, natural fallow and continuous maize, respectively. Total SOC stocks were also higher under fallows when compared with continuous maize at fallow termination and after two cropping seasons. Soil bulk densities were lower under fallows when compared with continuous maize during the period of study. We concluded that fallows maintained greater SOC and NT sequestered more SOC than CT. Acacia angustissima was the better tree legume fallow for SOC sequestration when compared with S. sesban or natural fallow because it maintained higher SOC and lower bulk densities after two seasons of maize cropping.", "keywords": ["2.

In the N-response trial, maize was grown annually receiving urea N at 0, 30, 60, 90 and 120 kg N ha\u22121. In Ibadan, maize production increased with N fertilization, but mean annual grain yield declined over the course of the trial. In Zaria, no response to N treatments was observed initially, and an increase in the phosphorus (P) and sulphur (S) fertilizer application rate was required to increase yield across treatments and obtain a response to N applications, stressing the importance of non-N fertilizers in the savannah. In the rotation trial, a 2-year natural fallow\u2013maize rotation was compared with maize rotated with different legume types: green manure, forage, dual-purpose, and grain legumes. The cultivation of some legume types resulted in a greater annual maize production relative to the fallow\u2013maize combination and corresponding treatments in the N-response trial, while there was no gain in maize yield with other legume types. Large differences in the residual effects from legumes and fallow were also observed between sites, indicting a need for site-specific land management recommendations. In Ibadan, cultivation of maize after the forage legume (Stylosanthes guianensis) achieved the highest yield. The natural fallow\u2013maize rotation had improved soil characteristics (Bray-I P, exchangeable potassium, calcium and magnesium) at the end of the trial relative to legume\u2013maize rotations, and natural fallow resulted in higher maize yields than the green manure legume (Pueraria phaseoloides). In Zaria, maize following dual-purpose soybean achieved the highest mean yield. At both sites, variation in aboveground N and P dynamics of the legume and fallow vegetation could only partly explain the different residual effects on maize.", "keywords": ["2.

We studied the effect of tillage and residue management on soil carbon sequestration and CO2 emissions in loam soil cropped in a winter wheat\u2013corn rotation in northern China. There were five treatments: mouldboard ploughing, rotary tillage and no-tillage with chopped residues (MC, RC and NC), additional no-tillage with whole residue (NW) and mouldboard ploughing without residue (CK). After 5\u00a0years of each tillage system, MC and RC had higher annual CO2 efflux from soil. The CO2 effluxes were correlated with the ratio of dissolved organic carbon to soil microbial biomass (DOC/MBC) among treatments. This effect may be due to less immobilization of soil carbon by microorganisms under long-time intensive tillage. Although both MBC and DOC showed seasonal variability, when averaged across the sampling period only MBC discriminated between treatments. After 5\u00a0years of tillage, all treatments except CK increased SOM (0.16\u20130.99\u00a0Mg\u00a0C\u00a0ha\u22121\u00a0year\u22121) at 0\u201330\u00a0cm depth and NC was the greatest, resulting from historical SOM depletion and large C return from recent residues. Despite the lowest CO2 flux being from the NW treatment, lower input residue from decreased biomass may have lowered C sequestration. To improve soil C sequestration in rotations, the input of residue and the CO2 emission should be balanced by adopting appropriate tillage and residue management.", "keywords": ["2.

The experiment consisted of eight treatments: non-fertilization (CK), nitrogen\u2013phosphorus fertilization (NP), phosphorus\u2013potassium fertilization (PK), nitrogen\u2013phosphorus\u2013potassium fertilization (NPK), pig manure (M), pig manure and NPK fertilization (NPKM), high rates of NPKM (hNPKM), and straw returned with inorganic fertilizers (NPKS). Applications of manure (i.e., M, NPKM and hNPKM) significantly increased soil organic carbon (SOC) and total nitrogen contents. Applications of inorganic fertilizers without manure showed small influences on SOC, but resulted in declines of soil total nitrogen over the long-term experiment. Grain yields were more than doubled under fertilizations for both wheat and corn, with the highest under the NPKM and hNPKM treatments and the lowest under non-fertilization. Long-term cropping practices without fertilization or with unbalanced fertilizations (e.g., NP and PK) caused low grain yields. The balanced fertilization of NPK increased grain yields. However, such practice was not able to maintain high grain yields during the last few years of experiment. Our analyses indicate that both wheat and corn grain yields are significantly correlated with SOC, total and available nitrogen and phosphorus. However, the relationships are stronger with total nitrogen (r\u00a0=\u00a00.5\u20130.6) than with available nitrogen (r\u00a0=\u00a00.26\u20130.3), indicating the importance of maintaining soil total nitrogen in agricultural practice.", "keywords": ["2.

The levels of SOC varied significantly with CCS (P \u2264 0.001), distance away from the center of the CCS (P \u2264 0.05), sampling depth (P \u2264 0.001), sampling year (P \u2264 0.001) and the interaction of CCS and soil depth (P \u2264 0.001). Sampling orientations did not significantly affect the levels of SOC. The SA sites had the highest level of SOC of 3.58 g kg\u22121, followed by WT sites (3.47 g kg\u22121) and MF sites (2.98 g kg\u22121). Results of our study did not support our hypothesis that cattle congregation sites typical on most ranches, such as MF, WT and SA, may have higher concentrations of SOC. The levels of SOC (averaged across CCS) within the congregation zone (3.42 g kg\u22121) were not significantly (P \u2264 0.05) different from the concentrations of SOC at the grazing zone (3.16 g kg\u22121).", "keywords": ["2.

However, the mechanisms underlying long-term accumulation and protection of soil organic carbon (SOC) in paddy fields have not been well documented. In the present study, five soil C fractions were separated by physical fractionation in a subtropical paddy field following 27-year differential fertilization regimes (started in 1981). Results showed that, compared to the initial level, long-term rice (Oryzasativa L.) cropping increased SOC concentrations by 28.8, 30.1, 30.8, and 61.6% in the non-fertilized (CK), nitrogen (N), nitrogen-phosphorus-potassium (NPK), and NPK combined with farmyard manure (NPK + FYM) treatments, respectively. Application of FYM enhanced the formation of macroaggregates (>2,000 and 250\u20132,000 \u03bcm), whereas no significant differences in aggregate-size distribution were found among the CK, N, and NPK treatments. Inorganic fertilization (N and NPK) did not affect the concentration of either total SOC or any C fraction as compared with the CK, whereas application of FYM significantly increased the concentrations both in total SOC (25.5%) and in all C fractions, except coarse particulate organic matter (cPOM). Carbon in the paddy soil was dominated by free silt and clay (s + c_f) and intra-aggregate particulate organic matter within microaggregates (iPOM_m) in all treatments that accounted for 46.4\u201349.6% and 25.1\u201327.2% of the total SOC, respectively. Furthermore, the differences in C in the iPOM_m and s + c_f fractions between the CK and NPK + FYM treatments accounted for 53.2 and 38.8% of the differences in total SOC stocks, respectively. These results indicate that SOC originating from manure is stored mainly in fractions with slow turnover (i.e., iPOM_m and s + c_f), which may benefit the long-term C sequestration in paddy soils.", "keywords": ["2.

It is accepted that such variations are likely to be associated, among other factors, with water spatial variations due to lateral water flows occurring in fields with undulating topography. However, some of the main processes governing water spatial distribution such as lateral flow are not entirely considered by the most commonly adopted crop simulation models. This brings uncertainty to the process of yield simulation at field-scale, especially under water-limited conditions. Although it is expected that lateral water movement determines spatial variations of crop yields, it is still unclear what is the net contribution of lateral water inflows (LIF) to spatial variations of rainfed yields in fields of undulating topography. In this sense, by combining field experimentation, simulation models (HYDRUS-1D and AquaCrop), and the use of artificial neural networks, we assessed the occurrence and magnitude of LIF, and their impact on wheat yields in Cordoba, Spain, over a 30-year period. Seasonal precipitation varied over 30 years from 212.8 to 759.5 mm, and cumulative LIF ranged from 30 to 125 mm. The ratio of seasonal cumulative LIF divided by seasonal precipitation varied from 10.7% to 38.9% over the 30 years. The net contribution of LIF to spatial variations of rainfed potential yields showed to be relevant but highly irregular among years. Despite the inter-annual variability, typical of Mediterranean conditions, the occurrence of LIF caused simulated wheat yields to vary + 16% from up to downslope areas of the field. The net yield responses to LIF, in downslope areas were on average 383 kg grain yield (GY) ha\u22121, and the LIF marginal water productivity reached 24.6 ( \u00b1 13.2) kg GY ha\u22121 mm\u22121 in years of maximum responsiveness. Decision makers are encouraged to take water spatial variations into account when adjusting management to different potential yielding zones within the same field. However, this process is expected to benefit from further advances in in-season weather forecasting that should be coupled with a methodological approach such as the one presented here.

Compared to the control treatment, the increase in SOC was 36, 33, and 19% greater in organic, integrated, and NPK treatments. The 16-years application of fertilizers and/or FYM resulted in much greater changes in water soluble C (WSC), microbial biomass C (MBC), light fraction of C (LFC), and particulate organic matter (POM) than SOC. Of the SOC, the proportion of POM was highest (24\u201335%), which was followed by LFC (12\u201314%), MBC (4.6\u20136.6%), and WSC (0.6\u20130.8%). The application of fertilizers and/or FYM increased the mean weight diameter of soil aggregates; thus provided physical protection to SOC from decomposition. Our results suggests that the application of fertilizers and/or FYM helps to sequester C in the soil and that the labile fractions of C can be used as indicators to determine the amount of C sequestered as a result of different management practices.", "keywords": ["2.

A long-term study has been performed to evaluate the environmental effects of energy crop cultivation on the loamy sand soil of the drier northeast region of Germany. The experimental field, established in 1994, consisted of columns (0.25\u00a0ha each) cultivated with short rotation coppice (SRC: Salix and Populus) and columns cultivated with annual crops. The columns were subdivided into four blocks, with each receiving different fertilization treatments. The soil C content was measured annually from 1994 until 1997, and then in 2006. Soil N2O levels were measured several times per week from 1999 to 2007. Water-filled pore space (WFPS) and soil nitrate measurements have been performed weekly since 2003. Increased C stocks were found in SRC columns, and C loss was observed in blocks with annual crops. The soil from fertilized blocks had higher levels of C than the soil from non-fertilized blocks. SRC cropping systems on dry, loamy sand soils are advantageous relative to annual cropping systems because of higher C sequestration, lower fertilized-induced N2O emissions, and reduced background N2O emissions in these soils. SRC cropping systems on dry, loamy sand soils have a CO2 advantage (approximately 4\u00a0Mg CO2 ha\u22121 year\u22121) relative to annual cropping systems.", "keywords": ["2. Zero hunger", "13.

We investigated changes occurring in soil organic carbon and nitrogen content, bulk chemical composition and in lignin as well as carbohydrate signature during 2 years after grassland conversion into arable land. Our results showed a rapid SOM decrease in the first few months after the conversion. The bulk chemical composition as seen by solid-state 13C NMR spectroscopy was similar under grassland and arable land, whereas different landuse had an impact on the contribution of plant litter compounds to SOM. SOM of arable soil had higher lignin contents and lower contents of non-cellulosic neutral carbohydrates than grassland soil. After grassland conversion, the most prominent change was an increase of the SOM\u2019s content of non-cellulosic carbohydrate above the contents recorded for grassland or arable land. Principal component analysis indicated that SOM chemical characteristics of converted grassland even after 2 years are similar to those of initial grassland. We conclude that the chemical composition of SOM is less susceptible to rapid change and that re-installation of grassland within some years will safeguard the initial SOM status in ley-arable rotations.", "keywords": ["[SDE] Environmental Sciences", "2.

To better understand the impact of management on soil N dynamics, we conducted field and laboratory research on five diverse management systems at a long-term study in Maryland, the USDA- Agricultural Research Service Beltsville Farming Systems Project (FSP). The FSP is comprised of a conventional no-till corn (Zea mays L.)\u2013soybean (Glycine max L.)\u2013wheat (Triticum aestivum L.)/double-crop soybean rotation (NT), a conventional chisel-till corn\u2013soybean\u2013wheat/soybean rotation (CT), a 2\u00a0year organic corn\u2013soybean rotation (Org2), a 3\u00a0year organic corn\u2013soybean\u2013wheat rotation (Org3), and a 6\u00a0year organic corn\u2013soybean\u2013wheat\u2013alfalfa (Medicago sativa L.)

Results showed that elevated CO2 significantly enhanced the biomass, tillers, leaf area index (LAI) and net assimilation rate (NAR) of rice, but reduced those of barnyard grass after elongation. Tissue nitrogen (N) concentrations were decreased in both competitors, but their phosphorus (P) and potassium (K) concentration were increased. The increase in tissue P concentration of rice was greater than that in barnyard grass. Furthermore, the absolute uptake of C, N, P, K by rice were increased while those of barnyard grass decreased. As a result, significant increase of the ratios of rice/barnyard grass of biomass and absolute nutrient uptake were observed under elevated CO2. The results suggest that rising atmospheric CO2 concentration could alter the competition between rice and barnyard grass in paddy fields in favor of rice. The ability of rice to compete more successfully for nitrogen and phosphorous under elevated CO2 is likely an important factor underlying this response.

The mass of LFOC and LFON in soil tended to increase with SRet (by 285\u00a0kg\u00a0C\u00a0ha\u22121 for LFOC and 12.6\u00a0kg\u00a0N\u00a0ha\u22121 for LFON with annual rate of 100\u00a0kg\u00a0N\u00a0ha\u22121 for 27\u00a0years), increased with N fertilizer application (by 517\u00a0kg\u00a0C\u00a0ha\u22121 for LFOC and 36.0\u00a0kg\u00a0N\u00a0ha\u22121 for LFON after 27\u00a0years), but was usually higher under CT than ZT (by 451\u00a0kg\u00a0C\u00a0ha\u22121 for LFOC and 25.3\u00a0kg\u00a0N\u00a0ha\u22121 for LFON after 27\u00a0years). Correlations between soil organic C or N fractions were highly significant in most cases. Linear regressions between crop residue C input and soil organic C or N were significant in most cases. The effects of tillage, straw management and N fertilizer on soil were more pronounced for LFOC and LFON than TOC and TON, and also in the surface layers than in the deeper layers. Tillage and straw management had little or no effect on C:N ratios, but the C:N ratios in light organic fractions significantly decreased with increasing N rate (from 20.06 at zero-N to 18.91 at 100\u00a0kg\u00a0N\u00a0ha\u22121). Compared to the 1979 results, in treatments that did not receive N fertilizer (CTSRem0, CTSRet0, ZTSRem0 and ZTSRet0), CTSRem0 resulted in a net decrease in TOC concentration (by 1.9\u00a0g\u00a0C\u00a0kg\u22121) in the 0\u201315\u00a0cm soil layer in 2007 (after 27\u00a0years), with little or no change in the CTSRet0 and ZTSRem0 treatments, while there was a net increase in TOC concentration (by 1.2\u00a0g\u00a0C\u00a0kg\u22121) in the ZTSRet0 treatment. Straw retention and N fertilizer application at 50 and 100\u00a0kg\u00a0N\u00a0ha\u22121 rates showed a net positive effect on TOC concentration under both ZT (ZTSRet50 by 2.3\u00a0g\u00a0C\u00a0kg\u22121 and ZTSRet100 by 3.1\u00a0g\u00a0C\u00a0kg\u22121) and CT (CTSRet50 by 3.5\u00a0g\u00a0C\u00a0kg\u22121 and CTSRet100 by 1.6\u00a0g\u00a0C\u00a0kg\u22121) treatments in 2007 compared to 1979 data. In conclusion, the findings suggest that retention of straw, application of N fertilizer and elimination of tillage would improve soil quality, and this might increase the potential for N supplying power of the soil and sustainability of crop productivity.", "keywords": ["2.

The objective of this study was to evaluate the effects of a summer catch crop and reduced N application rates on N leaching and vegetable crop yields. During a 2-year period, sweet corn as an N catch crop was planted between vegetable crops in the summer season under 5\u00a0N fertilizer treatments (0, 348, 522, 696, and 870\u00a0kg\u00a0ha\u22121) in greenhouse vegetable production systems in Tai Lake region, southern China. A water collection system was installed at a depth of 0.5\u00a0m in the soil to collect leachates during the vegetable growing season. The sweet corn as a catch crop reduced the total N concentration from 94 to 59\u00a0mg\u00a0l\u22121 in leached water and reduced the average soil nitrate N from 306 to 195\u00a0mg\u00a0kg\u22121 in the top 0.1-m soil during the fallow period of local farmers\u2019 N application rate (870\u00a0kg\u00a0ha\u22121).

A series of field experiments were carried out during October 2004 and September 2007 in a lysimeter field to reveal the temporal changes of N leaching losses below 2-m depth from this land system as well as the effects of N fertilizer application rates on N leaching. Four N rates (0, 180, 260, and 360 kg N ha(-1) as urea) were applied in the study area.

Our study aimed to determine if aspects of CA, namely tillage and mulching with manure and fertiliser application, improved soil mineral N release, plant N uptake and maize yields in cropping systems on poor soils in semi-arid Matobo, Zimbabwe. The experiment, run for three seasons (2012/13\u20132014/15), was a split-split plot design with three replicates. Tillage (animal-drawn ploughing and ripping) was the main plot treatment and residue application was the sub plot treatment with two levels (100% residues removed or retained after harvest). Five fertility amendments (mineral fertiliser at 0, 20 and 40 kg N ha-1, 5 t ha-1 manure only and 5 t ha-1 manure + 20 kg N ha-1) were sub-sub plot treatments. Plough tillage stimulated N mineralisation by 4\u201319 kg N ha-1 and maize N uptake 13\u201323% more than the ripper tillage. When mulch was added to the plough tillage, mineralisation was slowed resulting in less crop N uptake (by 5\u201319%) compared with no mulch application. N uptake was highest in the manure treatments. N recovery and agronomic N efficiency by maize were highly variable over the three seasons, reflecting the uncertainty complicating farmers\u2019 decision making. Nitrogen recovery in the manure treatments was generally poor in the first season resulting in low grain yields in the range 100\u2013260 kg ha-1 regardless of tillage, though higher in subsequent seasons. In the second season manure application gave the largest grain yields under the ripper tillage, both with and without mulch averaging 1850 and 2228 kg ha-1 respectively. Under the plough tillage, the 40 kg N ha-1 treatment gave the highest grain yields of 1985 kg ha-1. In the third season yields were generally poor under all treatments due to low and poorly-distributed rainfall. The CA principles of minimum soil disturbance and maintenance of a permanent mulch cover resulted in reduced soil mineral N availability for crop uptake and poor maize yields.

Four different water regimes, i.e., early aeration, normal aeration (the same as the local practice in timing and duration of aeration), delayed aeration, and prolonged aeration, were adopted separately and compared with respect to global warming potential (GWP) of CH4 and N2O emissions and rice yields as well.

Results showed that averaged across all the treatments about 75\u00a0% of the seasonal total CH4 occurred between the rice transplanting and booting stage, while constituted only 33\u00a0% of the seasonal total rice biomass during the same period.

In a similar way, the GHG intensity increased from 8.6 \u00b1 79.2 kg CO2eq kg\u22121 liveweight gain at LG up to 62.2 \u00b1 45.8 and 62.6 \u00b1 46.7 kg CO2eq kg\u22121 liveweight gain at MG and HG, respectively. GHG balances were predominantly determined by CO2 from changes in topsoil organic carbon. In grazing systems, CH4 from enteric fermentation was the second most important component. The results suggest that sheep grazing under the current management changes this steppe ecosystem from a sink to a source of GHGs and that grazing exclusion holds large potential to restore soil organic carbon stocks and thus to sequester atmospheric CO2. The balance between grazing intensity and grazing exclusion predominantly determines GHG balances of grass-based sheep farming in this region. Therefore, a high proportion of ungrazed land is most important for reducing GHG balances of sheep farms. This can be either achieved by high grazing intensity on the remaining grazed land or by confined hay feeding of sheep.", "keywords": ["2.

We aim to contribute with a mechanistic understanding on the effects that the preservation of herbaceous cover and the use of chemical fertilizers have on the performance of olive trees and on the biogeochemical cycles of the agroecosystem. We compared nutrient fluxes and aboveground leafy stocks in an olive grove that had been organically managed for more than 60 years, in a treatment in which the annual spontaneous herbaceous cover was maintained (H), and after two years of shift to conventional management treatments in which the growth of herbaceous vegetation was avoided by the use of herbicides (NH), and where exclusion of the herbaceous cover is also combined with the supply of mineral fertilizers (NHF). Maintenance of herbaceous vegetation in H contributed to the retention of a high aboveground capital of C and nutrients, particularly nitrogen, (N), phosphorus (P) and potassium (K) that were about 2.9, 3.9 and 7.4 times greater than in NH, respectively. The permanence of herbaceous cover stimulated olive tree leaf litter decomposition rates by about 86 % and increased nutrient release. However, the H treatment led to a 37 % decrease in olive yield and lowered olive foliar N and P content as negative short-term effects. The addition of fertilizers (N, P, K, and Mg) in mineral and solid form in NHF resulted inefficient to improve olive tree nutritional status and olive production, and decelerated olive tree litter decomposition rates by 21 % and nutrient release. The nutrient retention in organic forms in the fast-growing species of herbaceous covers and the progressive nutrient release as litter decomposes may contribute to regulate and better adapt nutrient availability to the nutrient requirements of olive trees.", "keywords": ["2.

Our results revealed that the elevated atmospheric CO2 increased the seasonal cumulative CH4 emissions by 15 % on average during the 4-year period. The increase was insignificant and much weaker than the previous studies, which might be primarily attributed to the absence of a significant difference in the rice biomass between the two CO2 levels in half of the field treatments. Crop residue incorporation hindered the stimulatory effects induced by the elevated CO2, which were 37, 14 and 6 % for the fields that were incorporated with none, half or all of the wheat straws that were harvested in the preceding winter wheat season, respectively. Nitrogen fertilizers application also hindered the stimulatory effects of the elevated CO2 on the CH4 emissions. The CO2 stimulatory effect was 39 % for the field without nitrogen fertilizers, and reduced to 17, 7 and 5 % for the field with nitrogen fertilization of 125, 250 and 350 kg N ha(-1), respectively. The regulation of nitrogen fertilizers on the CO2 effects in this experiment does not well agree with the previous studies, which might because the soil type was different from those of the previous studies. Thus, further studies are necessary to evaluate the role of soil properties in regulating the effects of elevated atmospheric CO2 on CH4 emissions from managed and natural wetlands. There were no significant interactions between the atmospheric CO2 and the incorporations of nitrogen fertilizer and crop residue.

Four nitrogen treatments were applied at a rate of 40\u00a0kg\u00a0N\u00a0ha\u22121: granular urea, \u2018Green Urea\u2122 14\u2019 [containing 45.8\u00a0% N as urea and \u2018Agrotain\u00ae\u2019 (N-(n-butyl) thiophosphoric triamide) @ 5\u00a0L\u00a0t\u22121 of urea as a urease inhibitor], \u2018Nhance\u2019, a fine particle spray [containing 46\u00a0% N as urea, \u2018Agrotain\u2019 @ 1\u00a0L\u00a0t\u22121 of urea and gibberellic acid (applied at a rate of 10\u00a0g\u00a0ha\u22121)] and urea ammonium nitrate in solution (UAN) surface applied. Ammonia loss was determined in autumn and spring using a micrometeorological method. In autumn, use of the Green Urea and Nhance reduced NH3 loss from the 30\u00a0% of applied N lost from the granular urea to 9 and 23\u00a0% respectively. Loss from all treatments in spring was very small (<2\u00a0% of applied N), because 4\u00a0mm of rain fell within 24\u00a0h of application onto an already wet site. The use of the Nhance and Green Urea instead of granular urea did not result in increased agronomic efficiency or recovery efficiency of the applied N, and this is most likely due to the presence of sufficient available N from both fertiliser application and the soil. A 15N study recovered 72.8\u00a0% of the applied N in the plants and soil, and showed that 30\u00a0% of the total N taken up by the plant was derived from the fertiliser, and 70\u00a0% from the soil.", "keywords": ["2.

A 2-year field experiment was conducted to assess the separation of nitrogen (N) fertilizer and irrigation water with alternating furrow irrigation (SNWAFI) in a maize (Zea mays L.) production system. Irrigation water use efficiency and nitrogen use efficiency with SNWAFI were generally greater than with conventional irrigation and fertilization (CIF). Response surfaces indicated that maximum maize yields were obtained with 238\u00a0kg urea-N\u00a0ha\u22121 and 106\u00a0mm irrigation water in 2008 and 244\u00a0kg urea-N\u00a0ha\u22121 and 95\u00a0mm of irrigation water in 2009. When the predicted yields were highest (6,384 and 6,549\u00a0kg\u00a0ha\u22121), water use efficiency, N uptake, and N use efficiency were greater with SNWAFI than CIF. Conversely, soil NO3\u2013N change during maize growing season decreased with SNWAFI compared CIF. With SNWAFI, optimizing irrigation water and N fertilizer rates can maximize yield, save irrigation water, and reduce N leaching.", "keywords": ["0106 biological sciences", "2.
