Microbial functional diversity in litter and soil has been hypothesized to affect the rate of decomposition of organic matter and other soil ecosystem functions. However, there are no clear theoretical expectations on how these effects might change with substrate availability, heterogeneity in the substrate chemistry, and different aspects of functional diversity itself (number of microbial groups vs. distribution of functional traits). To explore how these factors shape the decomposition-diversity relation, we carry out numerical experiments using a flexible reaction network comprising microbial processes and interactions with bioavailable carbon (extracellular degradation, uptake, respiration, growth, and mortality), and ecological processes (competition among the different groups). We also considered diverse carbon substrates, in terms of varying nominal oxidation state of carbon (NOSC). The reaction network was used to test the effects of (i) number of microbial groups, (ii) number of carbon pools, (iii) microbial functional diversity, and (iv) amount of bioavailable carbon. We found that the decomposition rate constant increases with increasing substrate concentration and heterogeneity, as well as with increasing microbial functional diversity or variance of microbial traits, albeit these biological factors are less important. The multivariate dependence of the decomposition rate constant (and other decomposition and microbial growth metrics) on substrate and microbial factors can be described using power laws with exponents lower than one, indicating that diversity effects on decomposition and microbial growth are reduced at high substrate concentration and heterogeneity, or at high microbial diversity.
Many studies have attempted to predict whether coastal marshes will be able to keep up with future acceleration of sea-level rise by estimating marsh accretion rates. However, there are few studies focussing on the long-term effects of herbivores on vegetation structure and subsequent effects on marsh accretion. Deposition of fine-grained, mineral sediment during tidal inundations, together with organic matter accumulation from the local vegetation, positively affects accretion rates of marsh surfaces. Tall vegetation can enhance sediment deposition by reducing current flow and wave action. Herbivores shorten vegetation height and this could potentially reduce sediment deposition. This study estimated the effects of herbivores on 1) vegetation height, 2) sediment deposition and 3) resulting marsh accretion after long-term (at least 16 years) herbivore exclusion of both small (i.e. hare and goose) and large grazers (i.e. cattle) for marshes of different ages. Our results firstly showed that both small and large herbivores can have a major impact on vegetation height. Secondly, grazing processes did not affect sediment deposition. Finally, trampling by large grazers affected marsh accretion rates by compacting the soil. In many European marshes, grazing is used as a tool in nature management as well as for agricultural purposes. Thus, we propose that soil compaction by large grazers should be taken in account when estimating the ability of coastal systems to cope with an accelerating sea-level rise. (C) 2013 Elsevier Ltd.

Saltmarshes are highly dynamic, grass dominated ecosystems: their large area, high salinity and location imply that they could efficiently contribute to the buffering of silica depletion events in the coastal zone. As grazing management potentially alters vegetation and sedimentation dynamics in saltmarshes, it could have an indirect impact on silica cycling in these systems. In two saltmarshes of the Wadden Sea coast, concentrations of dissolved and biogenic silica (DSi and BSi) were measured in eight creeks in four seasons under different management conditions. Export rates were calculated using simultaneous discharge measurements. Mean annual DSi concentration in the seepage water was 338\u00a0\u00b1\u00a0112\u00a0\u03bcmol\u00a0l \u22121 . Ungrazed sites had significantly higher seepage water DSi concentrations than sites which were grazed by sheep. BSi concentrations were, in general, lower and more variable. DSi export rates from ungrazed sites (265\u00a0\u00b1\u00a0155\u00a0\u03bcmol\u00a0m \u22122 \u00a0day \u22121 ) were twice as high as from grazed saltmarshes (126\u00a0\u00b1\u00a0137\u00a0\u03bcmol\u00a0m \u22122 \u00a0day \u22121 ). DSi concentrations were among the highest values previously reported for saltmarshes and tidal freshwater marshes.

Although accretion rates and the resulting surface elevation change largely determine the resilience of salt marshes to sea-level rise (SLR), the effect of livestock grazing on accretion rates has been little studied. Therefore, this study aimed to investigate the effect of livestock grazing on salt-marsh accretion rates. We hypothesise that accretion will be lower in grazed compared to ungrazed salt marshes. In four study sites along the mainland coast of the Wadden Sea (in the south-eastern North Sea), accretion rates, sediment deposition rates, and soil compaction of grazed and ungrazed marshes were analysed using the Cs-137 radionuclide dating method. Accretion rates were on average 11.6 mm yr(-1) during recent decades and thus higher than current and projected rates of SLR. Neither accretion nor sediment deposition rates were significantly different between grazing treatments. Meanwhile, soil compaction was clearly affected by grazing with significantly higher dry bulk density on grazed compared to ungrazed parts. Based on these results, we conclude that other factors influence whether grazing has an effect on accretion and sediment deposition rates and that the effect of grazing on marsh growth does not follow a direct causal chain. It may have a great importance when interacting with other biotic and abiotic processes on the marsh. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.

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

We investigated the potential to produce mulch by growing Tephrosia vogelii either intercropped with smallholder coffee or in arable fields outside the coffee, and the effect of the mulch on coffee yields over two years. Two accessions of T. vogelii (ex. Gisagara, Rwanda and ex. Kisumu, Kenya) were grown for six months both within and outside smallholder coffee fields in the first year. Experimental blocks were replicated across eight smallholder farms, only a single replicate per farm due to the small farm sizes. The accession from Rwanda (T. vogelii ex. Gisagara) grew more vigorously in all experiments. Soils within the coffee fields were more fertile those outside the coffee fields, presumably due to farmers\u2019 long-term management with mulch. Tephrosia grew less well in the fields outside coffee, producing only 0.6\u20130.7\u00a0Mg\u00a0ha\u22121 of biomass and adding (in kg\u00a0ha\u22121) 19 N, 1 P and 6 K in the mulch. By contrast, Tephrosia intercropped with coffee, produced 1.4\u20131.9\u00a0Mg\u00a0ha\u22121 of biomass and added (in kg\u00a0ha\u22121) 42\u201357 N, 3 P and 13\u201316 K in the mulch. Coffee yields were increased significantly by 400\u2013500\u00a0kg\u00a0ha\u22121 only in the treatments where Tephrosia was intercropped with coffee. Soil analysis and a missing-nutrient pot experiment showed that the poor growth of Tephrosia in the fields outside coffee was due to soil acidity (aluminium toxicity) combined with deficiencies of P, K and Ca. In the second year, the treatments in fields outside coffee were discontinued, and in the coffee intercrops, two Tephrosia accessions were grown in treatments with and without NPK fertilizer. Tephrosia grew well and produced between 2.5 and 3.8\u00a0Mg\u00a0ha\u22121 biomass for the two accessions when interplanted within coffee fields, adding 103\u2013150\u00a0kg\u00a0N\u00a0ha\u22121, 5\u20139\u00a0kg\u00a0P\u00a0ha\u22121 and 24\u201338\u00a0kg\u00a0K\u00a0ha\u22121. Tephrosia mulch increased yields of coffee by 400\u00a0kg\u00a0ha\u22121. Combined use of NPK\u00a0+\u00a0Tephrosia mulch increased Tephrosia biomass production and in turn yielded an additional 300\u2013700\u00a0kg\u00a0ha\u22121 of coffee. Over the two years, this was equivalent to a 23\u201336% increase in coffee yield using Tephrosia intercropping alone and a further 25\u201342% increase in coffee yield when NPK fertilizer was also added. Agronomic efficiency (AE) of nutrients added were 30% greater when the Tephrosia mulch was grown in situ and the two cultivars of Tephrosia did not differ in AE. The AE of Tephrosia mulch was 87% that of NPK fertilizer, reflecting the rapid mineralization of Tephrosia mulch. There was a synergistic effect of Tephrosia mulch on the efficiency with which NPK fertilizer was used by coffee. The increase in coffee yields was positively related to the amount of nutrients added in the Tephrosia biomass. Tephrosia intercropping required 30 man-days\u00a0ha\u22121 less than current farmer management due to reduced labour required for weeding, and benefit\u2013cost ratios ranged between 3.4 and 5.5.

Soil total organic carbon and labile organic carbon were significant increased in surface soil layer (0-10cm) under CT-r, NT-r, and NT-rr systems compared to that under CT-rr system. It indicated that conservation tillage practices can sequester soil organic carbon and reduced CO2/CH4 emission. Soil total nitrogen also significant increased in surface soil layer (0-10cm) under CT-r, NT-r, and NT-rr systems with the greatest under CT-r system (36%), followed by under NT-rr system (34%), and the least under NT-r system (20%) compared to CT-rr system. No-till, ridge culture, and rotation of rice and winter fallow were increased soil catalase and urease activities, but the greatest was not observed under NT-r system, under which the catalase activities was significant decreased. Soil invertase activities were significant increased under CT-r system compared to CT-rr systems and only a little increased in 0-20cm soil layer under NT-rr system.

Nanogenerators are emerging to be good candidates for converting the small-scale energies from the environment into electrical energy without need for battery. In this paper, a hybrid nanogenerator that integrates three different working mechanisms for conversion of mechanical energy into electrical energy is presented. The hybrid nanogenerator is composed of a zig-zag contact mode triboelectric nanogenerator (TENG), a sliding mode TENG and two electromagnetic generators (EMGs). Triboelectric surfaces are oppositely charged aluminium and Kapton layers for a zig-zag contact mode TENG and aluminium and PTFE layers for a sliding mode TENG. Aluminium layer is used as an electron donor, and also as an electrode. EMG unit is composed of two home-made copper coils and a neodymium magnet. All individual units are integrated into a two-piece acrylic shell. The whole device is of a compact, low-cost, and lightweight design. It has a size of 37\u00a0mm \u00d7 37\u00a0mm \u00d7 70\u00a0mm, which was optimized by modelling. Performance characterization verified the proposed hybrid nanogenerator as an efficient energy harvester. Output characteristics were tested under different loads (in a range from 10 k\u03a9 to 100 M\u03a9). The maximum output voltage and current of the hybrid nanogenerator were estimated to be about 65 V and 15.25 \u03bcA, respectively. The maximum output power was 1.13\u00a0mW at 200 \u03a9. Charging performance analysis showed that the hybrid nanogenerator significantly enhanced the voltage level and charging speed of the tested capacitors in comparison with individual units. The hybrid nanogenerator charged 1\u03bcF capacitor to 9.1 V within 60\u00a0s. Individual units could simultaneously power at least 144 light-emitting diodes (LEDs). A hybrid signal could power at least 94 LEDs connected in series and at least 50 LEDs connected in parallel. Electrical energy produced by the hybrid nanogenerator was stored in a 47 \u03bcF capacitor bank and used to efficiently power a calculator.", "keywords": ["Triboelectric nanogenerators", "Electromagnetic generators", "Hybrid nanogenerator", "Electrical engineering.

An elevated agrivoltaic system on arable land is evaluated: three crop light requirements (shade-loving, shade-tolerant and shade-intolerant) are simulated at a spatial resolution of 25 km across the European Union (EU). As a result, this study gives insight into the needed optimal ground coverage ratio (GCR) of the agrivoltaic system for a specific place. Additionally, estimations of the energy production, levelized cost of energy (LCOE) and land equivalent ratio (LER) are performed in comparison with a separated system. The results of the study show that the location-dependent solar insolation and crop shade tolerance have a major influence on the financial competitiveness and usefulness of these systems, where a proper European policy system and implementation strategy is required.

This paper presents the yields and crop quality results of the first 10 years. The experiment included three treatments with compost fertilization (9, 16 and 23\u00a0t\u00a0ha \u22121 \u00a0year \u22121 fresh matter (f.m.) on average of 10 years), three treatments with mineral nitrogen fertilization (25, 40.5 and 55.9\u00a0kg N ha \u22121 \u00a0year \u22121 on average), five treatments with combined fertilization and an untreated control in a latin rectangle design with a practical local crop sequence. The yield in the compost treatments increased for 8%, 7% and 10% compared to the unfertilized control (average of 10 years). Yield response to the compost applications was very low in the beginning and increased slightly with the duration of the experiment. This is likely due to the dry climatic conditions (552\u00a0mm precipitation), to the average C/N ratio of 23 in the composts used, and the high level of fertility of the Fluvisol on the site. The analysis of the yield components of the cereals showed that the plants in the compost treatments were sufficiently supplied with nitrogen in the early growth stages and after pollination, but at booting, when N-uptake is highest, the N-supply in the compost treatments was comparable to that with mineral fertilization at up to 30\u00a0kg N ha \u22121 . Crop quality was not affected by compost fertilization, but in some cases even improved. The results suggest that on fertile soils in the pannonic climate the fertilizer effect of biowaste compost is small, but increasing with time. The yields as well as the results concerning nitrogen availability during the vegetation period and crop quality show that the compost acted as a slow-release source of nitrogen on a medium level.", "keywords": ["2.

The main objective of this experiment was to measure the genotype\u00a0\u00d7\u00a0cropping system (G\u00a0\u00d7\u00a0CS) interaction for yield and selected agronomic traits of climbing beans ( Phaseolus vulgaris L.) grown as sole crop and intercropped with two morphologically contrasting maize ( Zea mays L.) cultivars. A secondary objective was to identify the most efficient and productive bean\u2013maize intercrop combinations. Seven climbing bean genotypes were grown as sole crop and intercropped with two maize varieties, BH 140 (Mix. 1) and Guto (Mix. 2), in a factorial arranged Randomized Complete Block Design with three replications at Bako Agricultural Research Center in western Ethiopia. Main effects due to genotype and cropping system (except days to flowering) were significant for all bean traits considered. The genotypes\u00a0\u00d7\u00a0cropping system interaction terms were also significant for the number of seeds per pod, 100-seed weight, harvest index and seed yield. While bean seed yield significantly correlated with the number of seeds per pod (in Mix. 1) and with harvest index (in both mixtures), positive and significant correlations occurred with the number of pods per plant and 100-seed weight under sole cropping system. The correlation between bean seed yields of Mix. 1 and Mix. 2 and between Mix. 2 and sole crop were positive and significant. No such relationship was found between Mix. 1 and sole crop. The results suggest that selection of suitable climbing bean cultivars for intercropping with maize varieties predominantly grown in the area should be made under the associated culture of the two crops. Intercropping contributed to a significant reduction in seed yield of the bean genotypes due mainly to its adverse effects on the numbers of pods per plant and seeds per pod. The index tLER 1 identified most bean\u2013maize genotype combinations of Mix. 2 as biologically more efficient system than Mix. 1. On the other hand, tLER 2 values of more than 1.00 for all treatments of Mix. 2 demonstrated higher overall productivity of the intercrop system when the bean genotypes were grown in association with a late-maturing and high yielding maize hybrid BH 140.", "keywords": ["2.

We measured the long-term sustainability of the system for farmyard manuring and mineral fertilizer input practices utilizing the trends in grain yield, partial factor productivity (PFP), agronomic efficiency (AE), benefit:cost ratio (B:C ratio), soil organic C (SOC), total N content, available nutrient (P and K) status, microbial biomass C, dehydrogenase activity, selected soil physical properties (bulk density, soil water retention and infiltration rate) and sustainable yield index (SYI). The long-term (30 years) soybean\u2013wheat experiment was conducted at Hawalbagh, Almora, India in a sandy loam soil (Typic haplaquept) under sub-temperate climatic conditions. Every year, the nutrients were applied to the soybean crop and wheat was grown without addition of any external sources of nutrients (residual wheat). The unfertilized plot supported a 0.56\u00a0Mg soybean yield ha\u22121 and a 0.71\u00a0Mg wheat yield ha\u22121 (mean yield of 30 years). Soybean responded to inorganic NPK application and the yield increased to 0.87\u00a0Mg\u00a0ha\u22121 with NPK. Maximum yields of soybean (2.84\u00a0Mg\u00a0ha\u22121) and subsequent wheat (1.88\u00a0Mg\u00a0ha\u22121) were obtained in the plots under NPK\u00a0+\u00a0farmyard manure (FYM) treatment. Soybean and residual wheat yields and PFP in the plots under the unfertilized and the inorganic fertilizer treatments decreased with time, whereas they increased in the plots under N\u00a0+\u00a0FYM and NPK\u00a0+\u00a0FYM treatments for both crops. The data revealed that SYI and AE of fertilizers were also greater in plots receiving fertilizer N or NPK along with 10\u00a0Mg\u00a0ha\u22121 FYM. Benefit:cost ratio of fertilization increased in both soybean and residual wheat for the plots under N\u00a0+\u00a0FYM and NPK\u00a0+\u00a0FYM, indicating that the benefit accruing from fertilization improved with time. After 30 years, total SOC and total N concentrations were increased in all treatments. Soils under NPK\u00a0+\u00a0FYM-treated plots contained higher total SOC and total N by 104% and 86% in the 0\u201315\u00a0cm soil layer, respectively, over that of initial soil. These differences in the total C content caused profound differences in soil physical properties. Available water capacity and water transmission characteristics in the soil were highest in the NPK\u00a0+\u00a0FYM treatment and lowest in the unfertilized treatments, with the mineral fertilizer treatments showing intermediate results. Combined use of NPK and FYM increased SOC, total N, Olsen P and ammonium acetate exchangeable K by 47%, 31%, 13% and 73%, respectively, in the 0\u201315\u00a0cm soil layer, compared to application of NPK through inorganic fertilizers. The application of NPK\u00a0+\u00a0FYM also showed the highest levels of soil microbial-biomass C and dehydrogenase activity. As total SOC and total N were increased after 30 years of the experiment in all the treatments, the decline in yields was probably due to a decline in available soil P and/or K. The results clearly reveal that current mineral-fertilizer recommendations are inadequate, whereas annual application of FYM along with NPK fertilizers sustains yield and soil productivity.", "keywords": ["2.

The tillage system consisted of conventional tillage vs. no-tillage and the crop rotation system consisted of two different 2-years rotations: wheat\u2013sunflower (Helianthus annuus L.) (WS) and wheat\u2013faba bean (Vicia faba L.) (WF). Fertilizer rates were 0 and 100\u00a0kg\u00a0N\u00a0ha\u22121 applied to wheat splitted in two amendments of 50\u00a0kg\u00a0N\u00a0ha\u22121 each. Two different fertilization systems were studied. In the old fertilized plots system fertilizer had been applied for 18 years since the beginning of the trial, and in the new fertilized plots system fertilizer was applied for the first time when this experiment was started. Measurements were carried out after fertilizer applications. In the long term, continued fertilizer application produced a higher soil total N content. Nevertheless, no increase in denitrification potential, N2O\u00a0+\u00a0N2 production by denitrification, N2O or CO2 emissions was observed either by the recent application of N or by the continued application during 18 years. The soil presented a higher potential to denitrify up to N2 than up to N2O. So, denitrification was probably occurring mainly in the form of N2, while N2O emissions were occurring in a great manner by nitrification, both denitrification and nitrification occurring simultaneously at soil field capacity (60\u201370%) expressed as water filled pore space (WFPS). Conventional tillage induced an increase in soil total N content and in the potential to denitrify up to N2 with respect to no-tillage. This higher potential was translated into higher N2O\u00a0+\u00a0N2 production by denitrification presumably stimulated in the short time by the higher available carbon provided by decomposing roots and by the subsequent creation of soil anaerobic microsites. Contrarily, no effect of tillage was observed on N2O emissions because of being produced in an important manner by nitrification, which does not depend on carbon availability. The wheat\u2013faba bean rotation induced higher soil nitrate contents than the wheat\u2013sunflower, although the effect in the long time was not observed regarding soil total N content. The same as for the fertilizer effect, this increase in nitrate content was not followed by a higher denitrification potential or higher N2O\u00a0+\u00a0N2 production by denitrification because of the lack of organic matter, while an increase was observed in N2O emissions.", "keywords": ["2.

Cotton (Gossypium hirsutum L.) and wheat (Triticum aestivum L.) crops were grown during the first three years (2008\u20132011) and in the last year, maize (Zea mays L.), wheat and green gram (Vigna radiate L.) were cultivated. Results indicate the plots under zero tillage with bed planting (ZT-B) and zero tillage with flat planting (ZT-F) had nearly 28 and 26% higher total SOC stock compared with conventional tillage and bed planting (CT-B) (\u223c5.5 Mg ha\u22121) in the 0\u20135 cm soil layer. Plots under ZT-B and ZT-F contained higher total SOC stocks in the 0\u20135 and 5\u201315 cm soil layers than CT-B plots. Although there were significant variations in total SOC stocks in the surface layers, SOC stocks were similar under all treatments in the 0\u201330 cm soil layer.

The objectives of the present study therefore were to investigate whether this negative effect of N fertilization on forage quality can be compensated by additional P application and also to determine the optimum fertilizer doses in rangelands to obtain economical benefits. Therefore, 0, 60, 120, 180\u00a0kg N\u00a0ha\u22121 and 0, 26, 52\u00a0kg P\u00a0ha\u22121 fertilizer rates were applied each year over a period of 3 years to 12 plots within each of 4 blocks. Botanical composition of the plots was determined and classified as grass, legumes and others for each treatment group based on dry weights. Dry matter yield, crude protein concentration and crude protein yield in treatment groups for each year were determined. Consequently, averaged over the 3 years of experimental period, nitrogen fertilizer increased the dry matter yield. The dry matter yield was 1467\u00a0kg\u00a0ha\u22121 in control plot, while it increased up to 3293\u00a0kg\u00a0ha\u22121 in plot applied with 180\u00a0kg N\u00a0ha\u22121 without P.

This effect can be explained by the observation that the nitrogen fertilization resulted in a decline of the legume proportion from 47% in the non-fertilized control to 5% with the highest N rate. The protein concentration in legume plants was always considerably higher than that in the grass and other species. Applying additional phosphorus compensated this negative effect of the nitrogen fertilization on the forage quality in terms of protein concentration.

Tillage treatments for rice ( Oryza sativa L.) were puddling by four passes of rotary puddler (PR), reduced puddling (ReP) for two passes of rotary puddler, conventional puddling (CP) and direct seeding without puddling (DSWP) in four replications. Tillage treatments for wheat ( Triticum aestivum L.) were zero tillage (ZT) and conventional tillage (CT) superimposed over the plots of rice tillage treatments. Puddling caused a significant reduction in saturated hydraulic conductivity (Ks), infiltration rate (IR), and specific volume (Rv). The reduction in Ks in the PR plot at 30 days after transplanting was 27 and 46% (3-year average) higher than in the ReP and DSWP plots, respectively, but was statistically at par with that in the CP plot in the surface tilled layer. This indicates that puddling by four passes of rotary puddler and that by conventional method adopted by farmers in those conditions gives the same level of control on percolation rate. Highest rice yield (5607\u00a0kg\u00a0ha \u22121 ) was obtained in the PR plot, which was statistically equal to that in the ReP plot. Wheat yield was highest (4020\u00a0kg\u00a0ha \u22121 ) in the DSWP plot of rice under CT condition. Total average grain production (rice\u00a0+\u00a0wheat) was highest under ReP\u2013CT treatment combination. Results thus show that quality of soil puddle obtained by half the efforts in conventional puddling was sufficient for a significantly high yield of rice with minimum deterioration of soil properties. Similarly, wheat sowing by conventional tillage in such a reduced puddling plots of rice was sufficient for a significantly high yield of wheat.", "keywords": ["2.

Three different seeding rates were evaluated. Italian ryegrass (Lolium multiflorum Lam.) decreased nitrate nitrogen (NO3-N) content in late autumn and timothy (Phleum pratense L.) in the succeeding spring.

To control soil acidity in no-till systems, lime is broadcast on the surface without incorporation. The effectiveness of surface application of lime to soils under a no-till system, particularly with regard to subsoil acidity, is uncertain. Crop root growth and grain yield can be affected by chemical modifications in the soil profile due to surface lime application. A 3-year field trial examined the effect of newly and previously surface-applied lime in a long-term no-till system on the root growth and crop yield of corn ( Zea mays L.), soybean ( Glycine max L. Merrill), and wheat ( Triticum aestivum L.) on a loamy, kaolinitic, thermic Typic Hapludox in Parana State, Brazil. The experiment consisted of four lime treatments: (i) no lime (control); (ii) liming at 3\u00a0t\u00a0ha \u22121 in 2000; (iii) liming at 6\u00a0t\u00a0ha \u22121 in 1993; (iv) liming in 1993 and re-liming in 2000. Corn was grown in 2000\u20132001 and soybeans were grown in 2001\u20132002 and 2002\u20132003 without rainfall limitation. Wheat was grown in 2003 with a water deficit during the vegetative stage and soon after flowering. Liming in 2000 increased pH and the content of exchangeable Ca 2+ , and decreased the exchangeable Al 3+ level mainly in the surface layer of the soil (0\u20135\u00a0cm). Compared with the no lime control, liming in 1993 ameliorated soil acidity and decreased aluminum toxicity to a 60\u00a0cm depth. Liming in 2000 on the previously limed plots compared with the liming in 1993 increased pH to a 10\u00a0cm depth about 1 year after application and to a 60\u00a0cm depth 3 years after application, indicating that the surface-applied lime in 2000 moved deeper when the topsoil was only slightly acidic. Root length density and grain yields of corn and soybean were not influenced by surface liming treatments. Liming in 2000 on the previously limed plots provided increases \u2265100% in length density of wheat roots at 0\u201310 and 10\u201320\u00a0cm depths, and increased the wheat grain yield by over 210%. A soil exchangeable Al 3+ level of 3\u00a0mmol (+) \u00a0dm \u22123 was considered critical for wheat root growth. Wheat grain yield was well correlated with root length per soil surface area.

Since 1966 up to now in the Southeast Po valley (Italy), the soil organic C (SOC) and total N (TN) dynamics in the 0\u20130.40\u00a0m soil layer under a maize\u2013wheat rainfed rotation are studied as influenced by organic and mineral N fertilizations. Every year in the same plots cattle manure, cattle slurry, and crop residues (i.e. wheat straw and maize stalk) are ploughed under to 0.40\u00a0m depth at a same dry matter rate (6.0 and 7.5\u00a0t\u00a0DM\u00a0ha \u22121 \u00a0year \u22121 after wheat and maize, respectively) and are compared to an unamended control.

In the whole experiment, in 2000 SOC concentration was lower than in 1966 (6.77 and 7.72\u00a0g\u00a0kg \u22121 , respectively), likely for the deeper tillage that diluted SOC and favoured mineralization in deeper soil layer. From 1972 to 2000 SOC stock did not change in the control and N fertilized plots, while it increased at mean rates of 0.16, 0.18, and 0.26\u00a0t\u00a0ha \u22121 \u00a0year \u22121 with the incorporation of residues, slurry and manure, corresponding to sequestration efficiencies of 3.7, 3.8 and 8.1% of added C with the various materials. TN followed the same SOC dynamic, demonstrating how it depends on the soil organic matter. Manure thus confirmed its efficacy in increasing both SOC content and soil fertility on the long-term. In developed countries, however, this material has become scarcely available; slurry management is expensive and implies high environmental risks. Moreover, in a C balance at a farm (or regional) scale, the CO 2 lost during manure and slurry stocking should be considered. For these reasons, the incorporation of cereal residues, even if only a little of their C content was found capable of soil accumulation, appears the best way to obtain a significant CO 2 sequestration in developed countries. Our long-term experiment clearly shows how difficult it is to modify SOC content. Moreover, because climate and soil type can greatly influence SOC dynamic, to increase CO 2 sequestration in cropland, it is important to optimize the fertilization within an agricultural management that includes all the agronomic practices (e.g. tillage, water management, cover crops, etc.) favouring the organic matter build up in the soil.", "keywords": ["2.

However, its development is still hampered in Mediterranean regions because of fears of severe competition for water. Recent studies have shown that soil resources other than water may also be restrictive, and particularly nitrogen. Over a three-year period, the effect of introducing a cover crop was studied with respect to the temporal and spatial changes to nitrogen dynamics in a Mediterranean vineyard. The experiment compared the impact of three different types of soil cover management on nitrogen dynamics, and particularly on soil nitrogen mineralization which is the principal source of inorganic nitrogen in situations with no application of N fertilizers which are frequent in viticulture. This experiment provided evidence that the presence of an intercrop significantly reduced nitrogen accumulation in aerial parts of grapevine during the year due to competition for soil resources. This reduction varied markedly between years and treatments, and was more pronounced during dry years. The competition for nitrogen was direct as intercrop deprived grapevine of soil nitrogen beneath the inter-row and caused grapevine uptake to be higher beneath the row. In deep soils, a grapevine can adapt its root system in order to access deeper water resources, but it then partially abandons the mineralization zone containing most inorganic nitrogen. Competition for nitrogen was less marked with a temporary cover crop than with a permanent one, because of the shorter period of uptake with the former and the time needed for an annual cover crop to develop its root system each year. Intercrop also competed indirectly for nitrogen with grapevine as it took up soil water and made inorganic nitrogen less mobile and accessible to grapevine. Intercrop markedly decreased soil nitrogen mineralization. Although it did not significantly affect organic matter characteristics or soil temperature, it clearly modified the water regime. Indeed, under either temporary or perennial cover crops, the upper soil layers dried more rapidly than when there was only evaporation from bare soil. Consequently, nitrogen mineralization decreased faster with intercropped treatments and halted prematurely during the summer. The earliness of the reduction in nitrogen accumulation in intercropped vineyards also suggested that a lower level of nitrogen transfer to perennial reserves was involved. Indeed, grass cover grows and competes for nitrogen during the autumn which is a favourable period for nitrogen accumulation in wood reserves. Although better water infiltration was observed in the presence of a cover crop (notably in the autumn), the favourable conditions for nitrogen mineralization were propitious for grass cover growth and uptake.

Straw manure is considered another important management practice to maintain soil organic matter content. This study compared effects of two organic manures (straw and farmyard manure) on soil properties and crop yields in a crop rotation system under semi-arid conditions. Soil physical, chemical and biological characteristics were determined in the experiment. After 25 years cropping and fertilization, two organic manures significantly influenced soil properties and crop yields. Farmyard manure combined with chemical fertilizer management (M + NP) resulted in higher increase in SOC, available-N, available-P, and higher activities of protease, urease, and alkaline-phosphatase compared with those found under straw manure combined with chemical fertilizer management (S + NP). However, soil of straw treatment had higher levels of potential soil respiration, soil water retention, microbial biomass, soil porosity, invertase, catalase and lower bulk density than farmyard manure treatment. M + NP produced the highest crop yields at all treatments. Biochemical properties of both treatments were positively correlated with SOC and nutrient content. These results indicate that straw management positively affected soil physical, chemical and biochemical properties as manure treatment in calcareous soil. Adding straw manure, as a replacement of farmyard manure, could be a promising strategy on some soil physical and biological properties as compared to farmyard manure in calcareous soil.", "keywords": ["2.

Three field experiments were carried out in Eastern Slovenia to examine the effects of Italian ryegrass ( Lolium multiflorum Lam.), winter rape ( Brassica napus ssp. oleifera (Metzg.) Sinsk), subclover ( Trifolium subterraneum L.), and crimson clover ( Trifolium incarnatum L.) as winter cover crops on the mineral N (N min ) content of soil and on the yield and N content of subsequent maize ( Zea mays L.), fertilized with 120\u00a0kg\u00a0N\u00a0ha \u22121 . Italian ryegrass and winter rape decreased soil N min contents before winter and in spring more than both clovers. In contrast, clovers accumulated significantly higher amounts of N in organic matter and had lower C/N ratios than winter rape and especially Italian ryegrass. In comparison to the control (bare fallow without cover crop), clovers increased the whole above ground maize dry matter yield, maize grain yield and N contents in whole above ground plants and in grain. The yields and N contents of maize following winter rape were on the same level as the control, while yields and N contents of maize following Italian ryegrass were, in two of the experiments, at the same level as the control. The effects of Italian ryegrass on the maize as subsequent crop in the third experiment were markedly negative. Maize in the control treatment exploited N much more efficiently than in treatments with cover crops. Therefore, cover crop N management should be improved, especially with a view to optimizing the timing of net N mineralization in accordance with the N demands of the subsequent crop.", "keywords": ["2.

Policymakers and farmers need scientific information to make appropriate land management decisions. Conventional (CT) and zero tillage (ZT) are two common soil management systems. Comparative field studies under controlled conditions are required to determine the impact of these systems on soil quality and yields. The research presented studied plant and soil physical and chemical characteristics as affected by different agricultural management practices, i.e. ZT and CT, cropped with continuous wheat or maize in monoculture (M) or in a yearly rotation (R) of these two crops, either with residue retention (+r) or without residues retention (\u2212r), in an experimental field in the Transvolcanic Belt of Mexico after 14 years. The dominant factors defining soil quality were organic C, total N, moisture, aggregate stability, mechanical resistance, pH and EC. The principal component combining the variables organic C, total N, aggregate stability and moisture content showed the highest correlations with final yield (R = 0.85 for wheat and 0.87 for maize). After 14 years of continuous practice, ZTM + r and ZTR + r had the best soil quality and produced the highest wheat and maize yields of average 2001\u20132004 (6683 and 7672 kg ha \u22121", "keywords": ["2.

If properly vegetated and managed, they can also produce wood for burning, act as sinks for atmospheric CO2 and enhance the landscape beauty. The paper presents an analysis of the different functions of BS and reviews the more important data from research programmes conducted over the last decade in Veneto Region (North-East Italy). Over a period of 3-5 years, in two experimental sites, young BS reduced total runoff by 33%, losses of N by 44% and P by 50% compared to no-BS. A mature BS was able to abate both NO3-N and dissolved phosphorus concentrations by almost 100%, in most cases having exiting water that satisfied the limit for avoiding eutrophication. The BS also proved to be a useful barrier for herbicides, with concentrations abated by 60% and 90%, depending on the chemical and the time elapsed since application. Considering the CO2 immobilized in the wood and soil together, the different BS monitored stored up to 80 t ha-1 year-1 . The BS caused negligible disturbance to maize, soybean and sugarbeet yields. The hedgerows, par- ticularly if composed of trees taller than 6 m, positively influenced the aesthetic value of the territory, improving its perceived naturalness and screening the man-made elements. Lastly, through a multi-objective analysis, opportunity costs were estimated to support the public decision-maker in determining the subsidies to be paid to encourage farmers to plant BS.", "keywords": ["2.

The study was conducted in a typical semiarid area during two growing seasons of 2006\u20132007 with the following three treatments: (i) plastic film mulching at maize sowing with conventional tillage, and the film was removed at harvest (CK); (ii) mulching applied 30 d before sowing with conventional tillage, and the film was removed at harvest (T1); and (iii) mulching at sowing with no-tillage, and the film left on the field after harvest in the first season and used for mulching in the second season (T2). The T1 in both years and T2 in the second year (2007) improved soil water content (in the 0\u201360 cm layer) and temperature (10 cm) at sowing compared with CK. After the two seasons, the soil water content was significantly higher in the 0\u201380 cm soil layer in CK and T1, and in the 0\u2013120 cm soil layer in T2; however, it decreased significantly in 140\u2013200 cm soil layer in CK and T1, compared to their initial values at sowing in April 2006, and there was no significant change in T2. The rainfall storage in the 0\u2013200 cm soil layer during the non-growing season (late September 2006 to late April 2007) was 18.2 mm in CK, 34.0 mm in T1, and 59.7 mm in T2, and the rainfall storage in 100\u2013200 cm soil layer was 16.5 and 18.6 mm higher in T2 than in CK and T1, respectively. In 2006, there were no significant differences in yield and water use efficiency (WUE) in all treatments. In 2007, the yield in T1 was significantly higher than in T2, but yields in T2 and CK were not significantly different, and there was no significant difference in WUE among treatments. Soil organic carbon (SOC) (0\u201320 cm) decreased in CK and T1, but increased (by 2.7%) in T2 at harvesting in September 2007 from the initial value of sowing in April 2006. The ratio of output to input was 1.32:1 for CK, 1.40:1 for T1, and 1.67:1 for T2 averaged across the two seasons. Therefore, T2 was a more sustainable model for increasing water storage, producing greater economic benefit and maintaining SOC balance for maize production in semiarid area.", "keywords": ["0106 biological sciences", "2.
