Since land\uffe2\uff80\uff90use change (LUC) to lignocellulosic biomass crops often causes a loss of soil organic carbon (SOC), at least in the short term, this study investigated the potential for pyrogenic carbon (PyC) to ameliorate this effect. Although negative priming has been observed in many studies, most of these are long\uffe2\uff80\uff90term incubation experiments which do not account for the interactions between environmentally weathered PyC and native SOC. Here, the aim was to assess the impact of environmentally weathered PyC on native SOC mineralization at different time points in LUC from arable crops to short rotation coppice (SRC) willow. At eight SRC willow plantations in England, with ages of 3\uffe2\uff80\uff9322\uffc2\uffa0years, soil amended 18\uffe2\uff80\uff9322\uffc2\uffa0months previously with PyC was compared with unamended control soil. Cumulative CO2 flux was measured weekly from incubated soil at 0\uffe2\uff80\uff935\uffc2\uffa0cm depth, and soil\uffe2\uff80\uff90surface CO2 flux was also measured in the field. For the incubated soil, cumulative CO2 flux was significantly higher from soil containing weathered PyC than the control soil for seven of the eight sites. Across all sites, the mean cumulative CO2 flux was 21% higher from soil incubated with weathered PyC than the control soil. These results indicate the potential for positive priming in the surface 5\uffc2\uffa0cm of soil independent of changes in soil properties following LUC to SRC willow production. However, no net effect on CO2 flux was observed in the field, suggesting this increase in CO2 is offset by a contrasting PyC\uffe2\uff80\uff90induced effect at a different soil depth or that different effects were observed under laboratory and field conditions. Although the mechanisms for these contrasting effects remain unclear, results presented here suggest that PyC does not reduce LUC\uffe2\uff80\uff90induced SOC losses through negative priming, at least for this PyC type and application rate.

A field experiment was conducted on a Ferric Lixisol at Gampela (Burkina Faso) in 2000 and 2001 to carried out the effects of tillage, fertilisation and their interaction on soil organic carbon (SOC) (0\u201310 cm), crop performance and microbial activities. Maize straw or sheep dung were applied separately or combined with urea in a till or no-till systems and compared with urea only and a control treatment. Sampling was done each year at 2 months after sowing and at harvest. SOC was increased in the tillage treatments in 2000 by 35% but only with 18% in 2001 suggesting reduced carbon accumulation in the absence of organic and mineral restitution. Ploughing in maize straw under conditions of N deficiency led to a drastic decrease in SOC due microbial priming effect that, was not observed when ploughing in sheep dung. In no-till system, losses, organic amendment N concentration and the soil N status determined the impact on SOC and crop productivity. The negative effect on SOC in the tillage treatment with maize straw (4.1 g kg \ufffd 1 ) was less when maize straw was combined with urea (6.2 g kg \ufffd 1 ). It is concluded that in semi-arid West Africa, without both organic resource and N inputs, soil organic matter \u2018\u2018pays\u2019\u2019 for crop N nutrition. Increasing SOC accumulation while improving crop yield may be conflicting under low-input agricultural systems in semi-arid West Africa.

However, little is known about potential interactive effects of plant diversity and warming on essential ecosystem properties, such as soil microbial functions and element cycling. We studied the effects of orthogonal manipulations of plant diversity (one, four, and 16 species) and warming (ambient, +1.5\uffc2\uffb0C, and +3\uffc2\uffb0C) on soil microbial biomass, respiration, growth after nutrient additions, and activities of extracellular enzymes in 2011 and 2012 in the BAC (biodiversity and climate) perennial grassland experiment site at Cedar Creek, Minnesota, USA. Focal enzymes are involved in essential biogeochemical processes of the carbon, nitrogen, and phosphorus cycles. Soil microbial biomass and some enzyme activities involved in the C and N cycle increased significantly with increasing plant diversity in both years. In addition, 16\uffe2\uff80\uff90species mixtures buffered warming induced reductions in topsoil water content.

Increasing plant diversity consistently decreased microbial biomass\uffe2\uff80\uff90specific enzyme activities and altered soil microbial growth responses to nutrient additions, indicating that plant diversity changed nutrient limitations and/or microbial community composition. In contrast to our expectations, higher plant diversity only buffered temperature effects on soil water content, but not on microbial functions. Temperature effects on some soil enzymes were greatest at high plant diversity. In total, our results suggest that the fundamental temperature ranges of soil microbial communities may be sufficiently broad to buffer their functioning against changes in temperature and that plant diversity may be a dominant control of soil microbial processes in a changing world.

Continuous CO2 andperiodical N2O soil emission measurements were performed during two periods: under maize cultivation (April 2003\u2013July 2003) and during the fallow period after wheat harvest (August 2003\u2013March 2004). 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.

Variable intensity field rainfall simulations were performed on 2 m long 1 m wide plots within a field in first-year disk and harrow following no-till (CT), and within a long-term no-tilled (NT) field, both treated with atrazine and glyphosate according to label.

Runoff was collected at regular time intervals during two simulated rainfall events and analyzed for herbicide concentration, sediment content, and volume. Maximum glyphosate concentration in runoff was 233 m gL 1 for NTand 180 m gL 1 for CT (approximately 33% and 26% of the maximum contaminant limit (MCL) forglyphosate (700 m gL 1 ), respectively, while maximum atrazine concentrations in runoff was 303 m gL 1 for NT and 79 m gL 1 for CT (approximately 100 times and 26 times the atrazine MCL (3 m gL 1 )). Atrazine concentration and loading were significantly higher in runoff from NT plots than from CT plots, whereas glyphosate concentration and loading were impacted by tillage treatment to a much lesser degree.

For that, the soil organic carbon (SOC) accumulation and the C equivalent (CE) costs of the investigated management systems were taken into account in comparison to the CT O/M 0\u00a0N used as reference system. No-till is known to produce a less oxidative environment than CT and resulted in SOC accumulation, mainly in the 0\u20135\u00a0cm soil layer, at rates related to the addition of crop residues, which were increased by legume cover crops and N fertilization.

However, the SOC accumulation rates peaked during the first years (5th to 9th) after the adoption of the management practices and decreased exponentially over time, indicating that conservation soil management was a short-term strategy for atmospheric C mitigation. On the other hand, when the CE costs of tillage operations were taken into account, the benefits of NT to C mitigation compared to CT were enhanced. When CE costs related to N-based fertilizers were taken into account, the increases in SOC accumulation due to N did not necessarily improve atmospheric C mitigation, although this does not diminish the agricultural and economic importance of inorganic N fertilization.", "keywords": ["2.

SOC stocks in the first 2\uffc2\uffa0m of soil ranged from 20\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a Sahelian savanna in Mali to over 120\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a transitional forest in Ghana. The degree of interdependence between soil bulk density (SBD) and soil properties is highlighted by the strong negative relationships observed between SBD and SOC (r2\uffc2\uffa0>\uffc2\uffa00.84). A simple predictive function capable of encompassing the effect of climate, soil properties and vegetation type on SOC stocks showed that available water and sand content taken together could explain 0.84 and 0.86 of the total variability in SOC stocks observed to 0.3 and 1.0\uffc2\uffa0m depth respectively. Used in combination with a suitable climatic parameter, sand content is a good predictor of SOC stored in highly weathered dry tropical ecosystems with arguably less confounding effects than provided by clay content. There was an increased contribution of resistant SOC to the total SOC pool for lower rainfall soils, this likely being the result of more frequent fire events in the grassier savannas of the more arid regions. This work provides new insights into the mechanisms determining the distribution of carbon storage in tropical soils and should contribute significantly to the development of robust predictive models of biogeochemical cycling and vegetation dynamics in tropical regions.

We collected soil samples and measured gas fluxes in tilled and control (non tilled pasture) 12 times at equally spaced intervals during October 2001 to quantify the effect of tillage.

Our objective was to adapt reduced tillage to organic farming by quantifying effects of tillage (plough versus chisel), fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators and crop yield. The experiment was initiated in 2002 on a Stagnic Eutric Cambisol (45% clay content) near Frick (Switzerland) where the average annual precipitation is 1000 mm. This report focuses on the conversion period and examines changes as tillage intensity was reduced. Soil samples were taken from the 0-10 cm and 10-20 cm depths and analysed for soil organic carbon (Corg), microbial biomass (Cmic), dehydrogenase activity (DHA) and earthworm density and biomass. Among the components tested, only tillage had any influence on these soil fertility indicators. Corg in the 0-10 cm soil layer increased by 7.4% (1.5 g Corg kg-1 soil, p < 0.001) with reduced tillage between 2002 and 2005, but remained constant with conventional tillage. Similarly, Cmic was 28% higher and DHA 27% (p < 0.001) higher with reduced than with conventional tillage in the soil layer 0-10 cm. In the 10-20 cm layer, there were no significant differences for these soil parameters between the tillage treatments. Tillage had no significant effect on total earthworm density and biomass. The abundance of endogeic, horizontally burrowing adult earthworms was 70% higher under reduced than conventional tillage but their biomass was 53% lower with reduced tillage. Wheat (Triticum aestivum L.) and spelt (Triticum spelta L.) yield decreased by 14% (p < 0.001) and 8% (p < 0.05), respectively, with reduced tillage, but sunflower (Helianthus annuus L.) yield was slightly higher with reduced tillage. Slurry fertilization enhanced wheat yield by 5% (p < 0.001) compared to compost fertilization.

Our objectives were to evaluate the effects of nitrogen (N) fertilization and cropping systems on soil organic carbon (SOC) and total N (TN) concentrations and pools. Replicated soil samples were collected in May 2004 to 90\u00a0cm depth from a 23-year-old experiment at the Northwestern Illinois Agricultural Research and Demonstration Center, Monmouth, IL. The SOC and TN concentrations and pools, soil bulk density ( \u03c1 b ) and soil C:N ratio were measured for five N rates [0 (N 0 ), 70 (N 1 ), 140 (N 2 ), 210 (N 3 ) and 280 (N 4 ) kg\u00a0N\u00a0ha \u22121 ] and two cropping systems [continuous corn ( Zea mays L.) (CC), and corn\u2013soybean ( Glycine max (L . ) Merr.) rotation (CS)]. Long-term N fertilization and cropping systems significantly influenced SOC concentrations and pools to 30\u00a0cm depth. The SOC pool in 0\u201330\u00a0cm depth ranged from 68.4\u00a0Mg\u00a0ha \u22121 for N 0 to 75.8\u00a0Mg\u00a0ha \u22121 for N 4 . Across all N treatments, the SOC pool in 0\u201330\u00a0cm depth for CC was 4.7\u00a0Mg\u00a0ha \u22121 greater than for CS. Similarly, TN concentrations and pools were also significantly affected by N rates. The TN pool for 0\u201330\u00a0cm depth ranged from 5.36\u00a0Mg\u00a0ha \u22121 for N 0 to 6.14\u00a0Mg\u00a0ha \u22121 for N 4 . In relation to cropping systems, the TN pool for 0\u201320\u00a0cm depth for CC was 0.4\u00a0Mg\u00a0ha \u22121 greater than for CS. The increase in SOC and TN pools with higher N rates is attributed to the increased amount of biomass production in CC and CS systems. Increasing N rates significantly decreased \u03c1 b for 0\u201330\u00a0cm and decreased the soil C:N ratio for 0\u201310\u00a0cm soil depth. However, none of the measured soil properties were significantly correlated with N rates and cropping systems below 30\u00a0cm soil depth. We conclude that in the context of developing productive and environmentally sustainable agricultural systems on a site and soil specific basis, the results from this study is helpful to strengthening the database of management effects on SOC storage in the Mollisols of Midwestern U.S.", "keywords": ["2.

The effects of conventional tillage (CT) with ploughing to 20\u00a0cm, reduced tillage (RT) with harrowing to 8\u201310\u00a0cm and direct drilling (DD) on CO 2 and N 2 O emissions from a loamy sand soil (8.1% clay, 3.5% organic matter) under spring barley undersown with ryegrass were measured by static chambers over a period of 113 days in spring and summer 2004 in a tillage experiment established in 2002 at Foulum, Denmark. There was a high temporal and spatial variation in both CO 2 and N 2 O emissions, which made the comparisons of treatment effects on emissions on single dates difficult. However, this variation was reduced when the measurements were corrected for diurnal variation in the emissions and when emissions were cumulated over a longer period. Both CO 2 and N 2 O emissions decreased in the order CT\u00a0>\u00a0RT\u00a0>\u00a0DD. Compared with CT (40\u00a0kg\u00a0C\u00a0day \u22121 ) the cumulated CO 2 emissions during the 91 days after tillage were 21 and 25% lower for the RT and the DD treatments, respectively.

The N 2 O emissions were significantly higher for CT compared with DD and RT, even before tillage and the difference increased after tillage, but decreased after fertilisation. Spring barley dry matter grain yields were reduced by 14% for RT and 27% for DD compared to CT. Measurements of soil mineral nitrogen (N) at sowing showed no difference between the treatments, and could thus not explain the differences in N 2 O emissions and crop N uptake. It is likely that tillage affected CO 2 emissions, N 2 O emissions and crop growth through different processes, where effects of soil compactness on root penetration and soil aeration and diffusivity on one side and soil organic matter turnover on the other side probably played key roles.", "keywords": ["2.

To determine possible carbon sinks in agriculture, it is necessary to study carbon sequestration potentials in relation to agricultural management. The aim of this paper is to evaluate the soil carbon sequestration potential of a site in north-eastern Switzerland under different tillage systems. The study was performed as a long-term (19-year) trial on an Orthic Luvisol (sandy loam) with a mean annual air temperature of 8.4\u00a0\u00b0C and a long-term precipitation mean of 1183\u00a0mm. The soil organic carbon (SOC) concentration was determined five times during the study period, with the paper focussing mainly on the year 2006. The main objective was to quantify the influence of mouldboard ploughing (PL), shallow tillage (ST), no-tillage (NT) practices, and grassland (GL) on soil organic carbon content, the latter's different fractions (labile, intermediate, and stable), and its distribution by depth. In calculating the SOC content of the whole soil profile, we included a correction factor accounting for variations in bulk density (equivalent soil mass). The total SOC stock at a depth of 0\u201340\u00a0cm was 65\u00a0Mg\u00a0C\u00a0ha \u22121 , and although higher under GL, did not differ significantly between PL, ST, and NT. SOC concentrations per soil layer were significantly greater for NT and ST (0\u201310\u00a0cm) than for PL, which had greater SOC concentrations than NT and ST at 20\u201330\u00a0cm depth. Both SOC concentrations and stocks (0\u201320\u00a0cm) were largest under GL. In all treatments, most of the carbon was found in the intermediate carbon fraction. There was no significant difference in any of the three SOC fractions between NT and ST, although there was between ST and PL. A sharp decrease in C-concentrations was observed in the first 7 years after the transition from grassland to arable land, with a new equilibrium of the carbon concentration in the 0\u201340\u00a0cm layer being reached 12 years later, with no significant difference between the tillage treatments.

The study was performed under three different land use scenarios: (1) forest; (2) abandoned agricultural field; and (3) non-irrigated olive grove. Experimental erosion plots (in olive grove and forest) and sediment traps (in the abandoned area) were used to determine the carbon pools associated with sediments and runoff after each event occurring between September 2005 and November 2006. Change in land use from forest to cultivated enhanced the risk of erosion (total soil loss in olive cropland seven-fold higher than in the forest area) and reduced the soil carbon stock (in the top 5 cm) by about 50%. Mineral-associated organic carbon (MOC) represented the main C pool in the three study areas although its contribution to soil organic carbon (SOC) was significantly higher in the disturbed areas (78.91 \u00b1 1.81% and 77.29 \u00b1 1.21% for abandoned and olive area, respectively) than in the forest area (66.05 \u00b1 3.11%). In both, the olive and abandoned soils, the reduction in particulate organic carbon (POC) was proportionally greater than the decline in MOC. The higher degree of sediment production in the olive cropland had an important consequence in terms of the carbon losses induced by erosion compared to the abandoned and forest plots. Thus, the total OC lost by erosion in the sediments was around three times higher in the cultivated (5.12 g C m\u22122) than the forest plot (1.77 g C m\u22122). The abandoned area displayed similar OC losses as a result of erosion as the forest plot (in the measurement period: 2.07 g C m\u22122, 0.63 g C m\u22122 and 0.65 g C m\u22122 for olive, forest and abandoned area, respectively). MOC represented the highest percentage of contribution to total sediment OC for all the events analysed and in all uses being, in general these values higher in Olive (74\u201390%) than in the other two areas (55\u201380%). The organic carbon lost was basically linked to the solid phase in the three land uses, although the contribution of DOC to total carbon loss by erosion varied widely with each event. Data from this study show that the more labile OC fraction (POC) lost in soil in the cultivated area was mainly due to the effect of cultivation (low overall biomass production and residue return together with high C mineralization) rather than to water erosion, given that the major part of the OC lost in sediments was in the form of MOC.", "keywords": ["2.

Subsidence in organic soils is caused primarily by aerobic degradation of soil organic matter (SOM), which in turn makes available large quantities of once bound C and N. Upon drainage and cultivation, soil C and N dynamics shift drastically. Organic soils transition from CO 2 and organic N sinks, to persistent sources, whereas CH 4 uptake capacity increases. Therefore, this study was conducted to assess the short-term (within the first year) impact of conversion of intensively tilled organic soils to no-till management. The specific objectives of this study were to: (i) compare soil moisture content, soil temperature, and greenhouse gas (GHG) emission rates from moldboard/disking (MB), no-till (NT), and bare (B) treatments in cultivated organic soils, and (ii) estimate the rate of subsidence associated with these tillage practices. Over the year, soil moisture content (SMC) was significantly higher in MB (0.90\u00a0kg\u00a0kg \u22121 ) than B (0.84\u00a0kg\u00a0kg \u22121 ) treatments; however NT (0.87\u00a0kg\u00a0kg \u22121 ) was not significantly different from either MB or B treatments. Mean annual temperatures at 5\u00a0cm depth were significantly higher in B (16.9\u00a0\u00b0C) compared to MB (16.2\u00a0\u00b0C) and NT (15.9\u00a0\u00b0C) treatments The CO 2 emissions were not significantly different among treatments, while N 2 O emissions were significantly higher from MB (96.9\u00a0kg\u00a0N 2 O-N\u00a0ha \u22121 \u00a0yr \u22121 ) than NT (35.8\u00a0kg\u00a0N 2 O-N\u00a0ha \u22121 \u00a0yr \u22121 ) plots. Both CH 4 uptake and CH 4 emission exhibited low annual flux in all treatments.", "keywords": ["2. Zero hunger", "13.

Agricultural sustainability problems resulting from soil erosion and fertility decline have arisen all over this agro-ecological zone. Based on selected soil quality indicators, i.e. time-to-pond, aggregate distribution and stability (expressed as the mean weight diameter (MWD) for dry and wet sieving, respectively) and soil moisture, from a representative long-term sustainability trial initiated in 1991 in Central Mexico (2240 masl; 19.31\u00b0N, 98.50\u00b0W; Cumulic Phaeozem), some insights into the feasibility of conservation agriculture (CA) as part of a sustainable production system in the tropical highlands are given. Zero tillage plots with crop residue removal showed low aggregate distribution (average MWD = 1.34 mm) and stability (average MWD = 0.99 mm) resulting in top layer slaking, increased erosion and low time-to-pond values. Retaining the residue in the field with zero tillage avoided the above-mentioned negative evolution for both aggregate distribution as stability (average MWD = 2.77 and 1.51 mm, respectively) and even improved the physical conditions of the soil as compared to conventional practice. Throughout the growing season the lowest soil moisture content was found in zero tillage without residue (average over the entire growing season = 20.5% volumetric moisture content), the highest in zero tillage with residue retention (average = 29.7%) while conventional tillage had intermediate soil moisture values (average = 27.4%). Zero tillage without residue retention had most days of soil moisture values under permanent wilting point, while zero tillage with residue retention had the least. Taking into account these results, zero tillage with residue retention can clearly be a part of an integrated watershed management scheme towards sustainable agriculture in the tropical highlands. It is clear that to develop new management practices to improve water use, reduce erosion and enhance human labor/animal power focus must be on the use of conservation agriculture both for rainfed as well as irrigated production systems and be fine tuned for each system.", "keywords": ["0106 biological sciences", "2.

The aim of this study was to quantify soil C sequestration, through the evaluation of the changes in C stocks, as well as the GHG fluxes (N 2 O and CH 4 ) during the process of conversion of Cerrado into agricultural land in the southwestern Amazon region, comparing no-tillage (NT) and conventional tillage (CT) systems. We collected samples from soils and made gas flux measurements in July 2004 (the dry season) and in January 2005 (the wet season) at six areas: Cerrado, CT cultivated with rice for 1 year (1CT) and 2 years (2CT), and NT cultivated with soybean for 1 year (1NT), 2 years (2NT) and 3 years (3NT), in each case after a 2-year period of rice under CT. Soil samples were analyzed in both seasons for total organic C and bulk density. The soil C stocks, corrected for a mass of soil equivalent to the 0\u201330-cm layer under Cerrado, indicated that soils under NT had generally higher C storage compared to native Cerrado and CT soils.

There were no CH 4 emissions to the atmosphere (negative fluxes) and there were no significant seasonal variations.

Measurements were conducted during four consecutive cropping seasons (July to October) from 1994 to 1997. Emission rates were very low (between 16 and 40 kg CH4 m-2season-1) when the field was flooded permanently. These low emissions were indirectly caused by the high percolation rates of the soil; frequent water replenishment resulted in constant inflow of oxygen in the soil. The local practice of intermittent flooding, which encompasses short periods without standing water in the field, further reduced emission rates. Over the course of four seasons, the total CH4 emission from intermittently irrigated fields was found to be 22% lower as compared with continuous flooding. The CH4 flux was invariably affected by rice cultivar. The experiments conducted during 1995 with one cultivar developed by IRRI (IR72) and two local cultivars (Pusa 169 and Pusa Basmati) showed that the average CH4 flux from the intermittently irrigated plots without any organic amendment ranged between 10.2 and 14.2 mg m-2 d-1. The impact of organic manure was tested in 1996 and 1997 with varieties IR72 and Pusa 169. Application of organic manure (FYM + wheat straw) in combination with urea (1:1 N basis) enhanced CH4 emission by I2-20% as compared with fields treated with urea only. The site in New Delhi represents one example of very low CH4 emissions from rice fields. Emissions from other sites in northern India may he higher than those in New Delhi, but they are still lower than in other rice-growing regions in India. The practice of intermittent irrigation\u2013in combination with low organic inputs is commonly found in northern India and will virtually impede further mitigation of CH4 emissions in significant quantities. In turn, the results of this study may provide clues to reduce emissions in other parts of India with higher baseline emissions.", "keywords": ["2. Zero hunger", "13. Climate action", "15.

Thus, the objective of this study was to evaluate the effects of tillage practices on N 2 O and CH 4 emissions in long-term continuous corn ( Zea mays ) plots. The study was conducted on continuous corn experimental plots established in 1962 on a Crosby silt loam (fine, mixed, mesic Aeric Ochraqualf) in Ohio. The experimental design consisted of NT, chisel till (CT) and moldboard plow till (MT) treatments arranged in a randomized block design with four replications. The N 2 O and CH 4 fluxes were measured for 1-year at 2-week intervals during growing season and at 4-week intervals during the off season. Long-term NT practice significantly decreased soil bulk density ( \u03c1 b ) and increased total N concentration of the 0\u201315\u00a0cm layer compared to MT and CT. Generally, NT treatment contained higher soil moisture contents and lower soil temperatures in the surface soil than CT and MT during summer, spring and autumn.

The N 2 O flux was strongly correlated with precipitation, air and soil temperatures, but not with gravimetric moisture content. Data from this study suggested that adoption of long-term NT under continuous corn cropping system in the U.S. Corn Belt region may reduce GWP associated with N 2 O and CH 4 emissions by approximately 50% compared to MT and CT management.", "keywords": ["2.

Rainfed agriculture on these soils is also hindered by the scarcity of water. No-tillage can increase plant-available water and soil organic matter, thus helping overcome most factors limiting crop production in this area. Our objective was to determine how conventional- and no-tillage practices affected soil physical quality indicators and water availability in an on-farm study in the Ebro Valley. Soil samples were collected from 0 to 5-, 5 to 15-, and 15 to 30-cm depth increments within adjacent farmer-managed conventional- and no-tillage fields in 2007 and 2008. Both fields were managed for continuous barley (Hordeum vulgare L.) production. The soil at both sites is a silt loam (Haplic Calcisol). Aggregate-size distribution and stability, soil water retention characteristics, organic carbon, and total carbonates were determined in 2007. Pore-size distribution was estimated from the water retention curve. Penetration resistance, soil bulk density and field water content during the entire crop growing season were measured for both fields in 2008. Aggregate dry mean weight diameter and stability in water were 1.2 and 2.2 times greater, respectively, under no-tillage than conventional tillage due to reduced mechanical disturbance and increased soil organic carbon content. Bulk density was 1.12 times greater (P\u00a0<\u00a00.1) under no-tillage only in the 0\u20135-cm depth. Two times greater penetration resistance to a depth of 15\u00a0cm in this treatment was related to bulk density and aggregates stability. Field water content was greater with no-tillage than conventional tillage during the driest months in 2008. The volume of equivalent diameter pores (0.2\u20139\u00a0\u03bcm) was 1.5 times higher under no-tillage. This increased plant-available water content and doubled barley production under no-tillage in 2008, which was a very dry year. We conclude that despite the greater penetration resistance under no-tillage, increased water availability as a result of improved structure characteristics was more important for crop yield. This suggests that producers should seriously consider adopting no-tillage practices for soil conservation in semiarid degraded areas like the one studied.", "keywords": ["2. Zero hunger", "13.

Either rotation of crops with pastures (ROT) or no-till (NT) cropping have been proposed as alternatives to minimize the impact of agriculture on soil quality. The combined impact on soil properties of ROT and NT has not been evaluated. In this study, we report results of the first 12 years of a long-term experiment established on a clay loam soil in western Uruguay. The objective was to determine the influence of conventional tillage (CT) and NT on systems under continuous cropping (CC, two crops per year) or ROT (3.5-year annual crops/2.5-year pastures). Soil samples taken at the beginning of the experiment in 1994 and in 2004 were analyzed for organic carbon (SOC), total organic carbon (TSOC) and total nitrogen content (STN), and for water-stable aggregation (WAS). Soil loss and erodibility indicators were studied using microrain simulator. With 12 years, the cumulative carbon (C) inputs of aboveground biomass were similar between tillage, but C input in CC was 50% higher than ROT. This difference was explained because 84% of the pastures dry matter was consumed by animals. Nevertheless we estimated a higher below ground biomass in ROT compared to CC systems (24.9\u00a0Mg\u00a0ha \u22121 vs. 10.9\u00a0Mg\u00a0ha \u22121 ). NT presented 7% higher SOC than CT (0\u201318\u00a0cm) with no differences between rotation systems. While all treatments declined in STN during 12 years, ROT had 11% and 58% higher STN and WAS than CC systems, with a large impact of the pasture under CT. Runoff and erosion were minimized under NT in both rotations systems. Thus, including pastures in the rotation, or switching from CT to NT improved soil quality properties. The expected benefit of combining NT and ROT will likely require more years for the cumulative effect to be detectable in both C input and soil properties.", "keywords": ["2. Zero hunger", "13.

In this study four tillage systems consisting of no-tillage with no fertilizer (NT0), conventional tillage with no fertilizer (CT0), no-tillage with compound fertilizer (NTC) and conventional tillage with compound fertilizer (CTC) applications in rice ( Oryza sativa L.) cultivation were compared in terms of the carbon dioxide (CO 2 ), methane (CH 4 ) and nitrous oxide (N 2 O) emissions from different tillage systems of the subtropical region of China during the rice growing season in 2008. GWPs based on CO 2 , CH 4 and N 2 O's cumulative emissions were also compared. Tillage and fertilization had no influence on CO 2 emissions. No-tillage had no effect on N 2 O emissions but significantly affected CH 4 emissions. Application of fertilizer significantly affected CH 4 and N 2 O emissions. Higher CH 4 emissions and lower N 2 O emissions were observed in CTC than in NTC. Cumulative CH 4 emission flux in NTC was 51.68\u00a0g\u00a0CH 4 \u00a0m \u22122 while it was 65.96\u00a0g\u00a0CH 4 \u00a0m \u22122 in CTC, 28% ( p 2 O emission flux in CTC was 561.00\u00a0mg\u00a0N 2 O\u00a0m \u22122 , and was 741.71\u00a0mg\u00a0N 2 O\u00a0m \u22122 in NTC, 33% ( p 2 O emissions between NT0 and CT0 systems, but significant in CH 4 emissions.

Our objective was to determine how three different tillage practices for monoculture of winter wheat ( Triticum aestivum L.) affected soil organic carbon (SOC) and N content after 11 years. Conventional tillage with residue removal (CT), shallow tillage with residue cover (ST), and no-tillage with residue cover (NT) were investigated. Carbon and N in various aggregate-size classes and various labile organic C fractions in the 0\u201315- and 15\u201330-cm soil layers were evaluated. The ST and NT treatments had 14.2 and 13.7% higher SOC stocks and 14.1 and 3.7% higher total N (N t ) stocks than CT in the upper 15\u00a0cm, respectively. Labile C fractions: particulate organic C (POC), permanganate oxidizable C (KMnO 4 -C), hot-water extractable C (HWC), microbial biomass C (MBC) and dissolved organic C (DOC) were all significantly higher in NT and ST than in CT in the upper 15\u00a0cm.

The portion of 0.25\u20132\u00a0mm aggregates, mean weight diameter (MWD) and geometric mean diameter (GMD) of aggregates from ST and NT treatments were larger than from CT at both 0\u201315- and 15\u201330-cm soil depths. The ST and NT treatments had significantly higher SOC and N t in the 0.25\u20132\u00a0mm fraction at both depths and significantly higher N t content in the upper 15\u00a0cm.

For soils amended with SS which the data on cation exchange capacity (CEC) were available, the relationships of PL and LL with CEC were significantly linear as with SOC.

The results suggest that there is a risk of increased N2O emissions in the first years of no-till practice under small grain spring cereal cultivation in Northern European boreal climate. Carbon dioxide emissions measured as total ecosystem respiration were either unchanged, increased or decreased under no-till. Fluxes of CH4 were negligible and not affected by no-till practice.

We hypothesized that this new type of management should have a profound impact on soil organic carbon (SOC) at regional scale and consequently on climate change mitigation. The objective of this study was thus to quantify the SOC storage potential of NTM in the oxisols of the Cerrado using a synchronic approach that is based on a chronosequence of fields of different years under NTM. The study consisted of three phases: (1) a farm/cropping system survey to identify the main types of NTM systems to be chosen for the chronosequence; (2) a field survey to identify a homogeneous set of situations for the chronosequence and (3) the characterization of the chronosequence to assess the SOC storage potential. Themain NTM system practiced by farmers is an annual succession of soybean (Glycine max) or maize (Zea mays) with another cereal crop. This cropping system covers 54% of the total cultivated area in the region. At the regional level, soil organic C concentrations from NTM fields were closely correlated with clay + silt content of the soil (r2 = 0.64). No significant correlation was observed (r2 = 0.07), however, between these two variables when we only considered the fields with a clay + silt content in the 500- 700 g kg_1 range. The final chronosequence of NTM fields was therefore based on a subsample of eight fields, within this textural range. The SOC stocks in the 0-30 cm topsoil layer of these selected fields varied between 4.2 and 6.7 kg C m_2 and increased on average (r2 = 0.97) with 0.19 kg C m_2 year_1. After 12 years of NTM management, SOC stocks were no longer significantly different from the stocks under natural Cerrado vegetation (p < 0.05), whereas a 23-year-old conventionally tilled and cropped field showed SOC stocks that were about 30% below this level. Confirming our hypotheses, this study clearly illustrated the high potential of NTM systems in increasing SOC storage under tropical conditions, and how a synchronic approach may be used to assess efficiently such modification on farmers' fields, identifying and excluding non desirable sources of heterogeneity (management, soils and climate).

A functional land management framework has been proposed to optimize the agro\uffe2\uff80\uff90environmental outputs from the land and specifically the supply and demand of soil functions such as (a) primary productivity, (b) carbon sequestration, (c) water purification and regulation, (d) biodiversity and (e) nutrient cycling, for which soil knowledge is essential. From the outset, the LANDMARK multi\uffe2\uff80\uff90actor research project integrates harvested knowledge from local, national and European stakeholders to develop such guidelines, creating a sense of ownership, trust and reciprocity of the outcomes. About 470 stakeholders from five European countries participated in 32 structured workshops covering multiple land uses in six climatic zones. The harmonized results include stakeholders\uffe2\uff80\uff99 priorities and concerns, perceptions on soil quality and functions, implementation of tools, management techniques, indicators and monitoring, activities and policies, knowledge gaps and ideas. Multi\uffe2\uff80\uff90criteria decision analysis was used for data analysis. Two qualitative models were developed using Decision EXpert methodology to evaluate \uffe2\uff80\uff9cknowledge\uffe2\uff80\uff9d and \uffe2\uff80\uff9cneeds\uffe2\uff80\uff9d. Soil quality perceptions differed across workshops, depending on the stakeholder level and regionally established terminologies. Stakeholders had good inherent knowledge about soil functioning, but several gaps were identified. In terms of critical requirements, stakeholders defined high technical, activity and policy needs in (a) financial incentives, (b) credible information on improving more sustainable management practices, (c) locally relevant advice, (d) farmers\uffe2\uff80\uff99 discussion groups, (e) training programmes, (f) funding for applied research and monitoring, and (g) strengthening soil science in education.
