More diverse crop rotations have been promoted for their potential to remediate the range of ecosystem services compromised by biologically simplified grain\uffe2\uff80\uff90based agroecosystems, including increasing soil organic carbon (SOC). We hypothesized that functional diversity offers a more predictive means of characterizing the impact of crop rotations on SOC concentrations than species diversity per se. Furthermore, we hypothesized that functional diversity can either increase or decrease SOC depending on its associated carbon (C) input to soil. We compiled a database of 27 cropping system sites and 169 cropping systems, recorded the species and functional diversity of crop rotations, SOC concentrations (g C kg/soil), nitrogen (N) fertilizer applications (kg\uffc2\uffa0N\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921), and estimated C input to soil (Mg\uffc2\uffa0C\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921). We categorized crop rotations into three broad categories: grain\uffe2\uff80\uff90only rotations, grain rotations with cover crops, and grain rotations with perennial crops. We divided the grain\uffe2\uff80\uff90only rotations into two sub\uffe2\uff80\uff90categories: cereal\uffe2\uff80\uff90only rotations and those that included both cereals and a legume grain. We compared changes in SOC and C input using mean effect sizes and 95% bootstrapped confidence intervals. Cover cropped and perennial cropped rotations, relative to grain\uffe2\uff80\uff90only rotations, increased C input by 42% and 23% and SOC concentrations by 6.3% and 12.5%, respectively. Within grain\uffe2\uff80\uff90only rotations, cereal\uffc2\uffa0+\uffc2\uffa0legume grain rotations decreased total C input (\uffe2\uff88\uff9216%), root C input (\uffe2\uff88\uff9212%), and SOC (\uffe2\uff88\uff925.3%) relative to cereal\uffe2\uff80\uff90only rotations. We found no effect of species diversity on SOC within grain\uffe2\uff80\uff90only rotations. N fertilizer rates mediated the effect of functional diversity on SOC within grain\uffe2\uff80\uff90only crop rotations: at low N fertilizer rates (\uffe2\uff89\uffa475\uffc2\uffa0kg N\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921), the decrease in SOC with cereal\uffc2\uffa0+\uffc2\uffa0legume grain rotations was less than at high N fertilizer rates. Our results show that increasing the functional diversity of crop rotations is more likely to increase SOC concentrations if it is accompanied by an increase in C input. Functionally diverse perennial and cover cropped rotations increased both C input and SOC concentrations, potentially by exploiting niches in time that would otherwise be unproductive, that is, increasing the \uffe2\uff80\uff9cperenniality\uffe2\uff80\uff9d of crop rotations.

Residual P And Leaf Management Effects On Maize Nutrition And Soil Properties", "description": "Agroforestry systems involving leaf removal for animal fodder may result in rapid depletion of soil fertility. The purpose of this research was to determine if the effects of leaf removal on soil fertility parameters and maize yield in a Leucaena leucocephala alley cropping system could be reversed. Three leaf management strategies in a Leucaena alley cropping trial that had been in effect from 1987 to 1991 were investigated: 1) leaves returned, 2) leaves removed, and 3) leaves removed, with 100 kg inorganic N ha\u22121 added. In the 1990/91 season, a 34 confounded factorial design was utilized to investigate the effects of leaf management strategy, N rate (0, 30 and 60 kg N ha\u22121); maize plant population (14,800, 29,600, and 44,400 plants ha\u22121); and P rate (0, 18, and 35 kg P ha\u22121). In the 1991/92 and 1992/93 seasons, leaves were applied equally to all plots, and no P was applied. The N rate and plant population treatments were continued, and the same confounded factorial design was implemented to investigate residual leaf management strategy, residual P rate, n rate, and plant population. The yield gap between the plots where leaves had been returned vs. removed narrowed each season due to uniform leaf application. Application of N improved yields during both seasons. Residual effects of the initial P application decreased to only 10% of the total yield in 1992/93. Plant population affected yields only during the season of very good rainfall. Leaf additions resulted in a relative increase in soil pH, total N,and exchangeable Ca, Mg, and K and a decrease C/N ratio in plots that had not previously received leaves. Leaves supplied more K and Zn to the upper 15 cm of soil than were being extracted by the maize crop, but uniform leaf additions eliminated differences in K and Zn uptake. Plant Zn uptake decreased with increasing P rate and plant population, and increased with increasing N rate and a history of leaf return. The results show that applying leaves equilibrated yields within two seasons, and resulted in a relative improvement of several soil properties. The residual effect from P applications was not adequate to maximize yields.", "keywords": ["alley cropping", "2.

The trial was carried out on an Alfisol in the humid zone of southwestern Nigeria. Hedgerows were established in 1983, using 4 m inter-hedgerow spacing and pruned to 25 cm height during cropping. Highest dry matter, wood, and nutrient yields of prunings of Acioa and Leucaena hedgerows were obtained with sole cropping. Growing Leucaena and Acioa in the same hedgerow suppressed dry matter production and nutrient yield of Acioa more than of Leucaena owing to the latter's faster growth. Total pruning dry matter yield was reduced as the proportion of Acioa increased in the combination. Leucaena prunings had higher nutrient yield than Acioa. Under 22-month old uncut hedgerows, weed biomass declined in the presence of Leucaena, either alone or in combination with Acioa. Weed weight under sole Leucaena hedgerows was about a third of that in the control plot. There was no significant effect of alley cropping on weed biomass, although alley cropping with Acioa and Leucaena hedgerows resulted in the dominance of broadleaf weeds while the control had a mixture of broadleaves and grasses. Alley cropping with various combinations of Acioa and Leucaena hedgerows increased maize and cowpea yields compared to control. Nitrogen application in both years increased maize grain yield. Mean yield increase due to N application in both years was highest in the control (47.2%) followed by the sole Acioa hedgerow (25.2%) and less in hedgerows with Leucaena.

The four-year results from five maize crops are reported. Except in the first year, yields of maize grain and stover were significantly reduced by 30% in the presence of leucaena hedgerows. Use of leucaena mulch eliminated this effect; application of all the harvested leucaena mulch (100%) increased the total maize grain yield of the five crops by 44% over sole maize. Hedgerow and mulching management required an additional 36 mandays labour ha\u22121 which was more than compensated by the increased maize yields. Furthermore leucaena hedgerows substantially depressed the growth of weeds between cropping seasons. Intercropping with cowpea significantly depressed yields of maize grain and stover when both crops were sown together, but not in later seasons when cowpea was sown four weeks after the maize. Application of slurry increased the total yields of maize grain and stover by 35 and 37%, respectively. The grain yield of maize in leucaena hedgerow treatments fertilized with slurry did not respond to application of more than 50% of leucaena foliage, which suggested that half of the foliage could be spared for feeding to livestock. The cumulative yield of maize grain from the highest yielding organic system was 85% of the yield from the fertilizer treatment.

The unfertilized plot supported 0.56 Mg ha\u22121 of soybean yield and 0.71 Mg ha\u22121 of wheat yield (average yield of 30 years). Soybean responded to inorganic NPK application and the yield increased significantly to 0.87 Mg ha\u22121 with NPK. Maximum yields of soybean (2.84 Mg ha\u22121) and residual wheat (1.88 Mg ha\u22121) were obtained in the plots under NPK + farmyard manure (FYM) treatment, which were significantly higher than yields observed under other treatments.

In both years, intercropping increased crop yield, changed N and P availability, and affected the microbiological properties in rhizosphere of the three species compared to sole cropping. Generally, intercropping increased microbial biomass C, N, and P availability, whereas it reduced microbial biomass N in rhizosphere of wheat. The rhizosphere bacterial community composition was studied by denaturing gradient gel electrophoresis of 16S rRNA. In the third year of different cropping systems, intercropping significantly changed bacterial community composition in rhizosphere compared with sole cropping, and the effects were most pronounced in the wheat/faba bean intercropping system.

Acacia intercropping significantly reduced sorghum grain yields while biochar had no significant effect on sorghum yields. The land equivalent ratio (LER) for sorghum yield was 0.3 for both acacia systems in 2011, with or without biochar, but increased in 2012 to 0.6 for the scattered acacia system when combined with biochar. The reduction in sorghum yields by the A. seyal trees was probably due to a combination of competition for water and nutrients and shading.

By stimulating indigenous arbuscular mycorrhizal fungi (AMF), cover cropping enhances soil health and promotes agroecosystem sustainability. Still, the legacy effects of cover crops (CCs) and the major factors driving the AM fungal community are not well known; neither is the influence of the specific CC. This work describes a field experiment established in Central Spain to test the effect of replacing winter fallow by barley (Hordeum vulgare L.) or vetch (Vicia sativa L.) during the intercropping of maize (Zea mays L.). We examined the community composition of the AMF in the roots and rhizosphere soil associated with the subsequent cash crop after 10\u202fyears of cover cropping, using Illumina technology. The multivariate analysis showed that the AMF communities under the barley treatment differed significantly from those under fallow, whereas no legacy effect of the vetch CC was detected. Soil organic carbon, electrical conductivity, pH, Ca and microbial biomass carbon were identified as major factors shaping soil AMF communities. Specific AMF taxa were found to play a role in plant uptake of P, Fe, Zn, Mn, and Cd, which may shed light on the functionality of these taxa. In our conditions, the use of barley as a winter CC appears to be an appropriate choice with respect to promotion of AMF populations and biological activity in agricultural soils with intercropping systems. However, more research on CC species and their legacy effect on the microbial community composition and functionality are needed to guide decisions in knowledge-based agriculture.", "keywords": ["Crops", " Agricultural", "2.

Relay intercropping with a legume cover crop can be a useful technique for improving N availability when two cash crops are grown successively. We evaluated the benefits of four relay intercropped legumes (Medicago lupulina, Medicago sativa, Trifolium pratense and Trifolium repens) on N dynamics and their contribution to the associated and subsequent cash crops in six fields of organic farms located in South-East France. None of the relay intercropped legumes affected the N uptake of the associated winter wheat but all significantly increased the N uptake of the succeeding spring crop, either maize or spring wheat. The improvement of the N nutrition of the subsequent maize crop induced a 30 % increase in grain yield. All relay intercropped legumes enriched the soil-plant system in N through symbiotic fixation. From 71 to 96 % of the N contained in the shoots of the legumes in late autumn was derived from the atmosphere (Ndfa) and varied between 38 and 67 kg Ndfa ha(-1). Even if the cover crop is expected to limit N leaching during wintertime, the presence of relay intercropped legumes had no significant effect on N leaching during winter compared to the control.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "2.

The experimental design consisted of two tillage treatments: reduced tillage (RT) and zero tillage (ZT), and three crop rotation treatments: continuous soybean (SS), corn\u2013soybean (CS), and soybean\u2013corn (SC). Soil samples were taken at soybean planting and harvest. The following quantifications were performed: soil microbial populations by soil dilution plate technique on selective and semi-selective culture media; microbial respiration and microbial biomass by chloroform fumigation-extraction; microbial activity by fluorescein diacetate hydrolysis; and fatty acid methyl ester (FAME) profiles. Soil chemical parameters were also quantified. Soil organic matter content was significantly lower in RT and SS sequence crops, whereas soil pH and total N were significantly higher in CS and SC sequence crops. Trichoderma and Gliocladium populations were lower under RTSS and ZTSS treatments. Except in a few cases, soil microbial respiration, biomass and activity were higher under zero tillage than under reduced tillage, both at planting and harvest sampling times. Multivariate analyses of FAMEs clearly separated both RT and ZT management practices at each sampling time; however, separation of sequence crops was less evident. In our experiments ZT treatment had highest proportion of 10Me 16:0, an actinomycetes biomarker, and 16:1\u03c99 and 18:1\u03c97, two fatty acids associated with organic matter content and substrate availability. In contrast, RT treatment had highest content of branched biomarkers (i15:0 and i16:0) and of cy19:0, fatty acids associated with cell stasis and/or stress. As cultural practices can influence soil microbial populations, it is important to analyze the effect that they produce on biological parameters, with the aim of conserving soil richness over time. Thus, in a soybean-based cropping system, appropriate crop management is necessary for a sustainable productivity without reducing soil quality.", "keywords": ["2.

P availability in the rhizosphere was increased in both sole cropping and intercropping systems compared with fallow. It was highest in intercropping. The increase in P availability was associated with (i) significant pH changes of the rhizosphere of cowpea in sole cropping and intercropping systems, with the rhizosphere acidification significantly higher in intercropping (\u22120.73\u00a0units) than in sole cropping (\u22120.42\u00a0units); (ii) significant increase in the rhizosphere pH of intercropped maize (+0.49\u00a0units) compared to fallow; (iii) increased soil respiration (C-CO2 from microbial and root activity) in intercropping compared with sole cropping and fallow; and (iv) higher efficiency in utilization of the rhizobial symbiosis in intercropping than in sole-cropped cowpea. With cowpea-maize intercropping, cowpea increased the P uptake, by increasing the P availability by rhizosphere pH changes in an alkaline soil.

In this study, we assess the impact of several diversification practices in different management regimes on the main carbon fluxes regulating the soil carbon balance under semiarid Mediterranean conditions.
MethodsThe study was conducted in two nearby cropping systems: (i) a low input rainfed almond (Prunus dulcis Mill.) orchard cultivated on terraces and (ii) a levelled intensively irrigated mandarin (Citrus reticulata Blanco) orchard with a street-ridge morphology. The almond trees were intercropped with Capparis spinosa or with Thymus hyemalis While the mandarin trees were intercropped with a mixture of barley and vetch followed by fava bean. Changes caused by crop diversifications on C inputs into the soil and C outputs from the soil were estimated.
ResultsCrop diversification did not affect soil organic carbon stocks but did affect the carbon inputs and outputs regulating the soil carbon balance of above Mediterranean agroecosystems. Crop diversification with perennials in the low-input rainfed woody crop system significantly improved the annual soil C balance in the short-term. However, crop diversification with annual species in the intensively managed woody crop system had not effect on the annual soil C balance.
ConclusionsOur results highlight the potential of intercropping with perennials in rainfed woody crop systems for climate change mitigation through soil carbon sequestration.

In this review we summarize recent advances in our knowledge of how plants, together with their associated microbiota, shape rhizosphere processes. We address (molecular) mechanisms operating at the plant\uffe2\uff80\uff93microbe-soil interface and aim to link this knowledge with actual and potential avenues for intensifying agricultural systems, while at the same time reducing irrigation water, fertilizer inputs and pesticide use. Combining in-depth knowledge about above and belowground plant traits will not only significantly advance our mechanistic understanding of involved processes but also allow for more informed decisions regarding agricultural practices and plant breeding. Including belowground plant-soil-microbe interactions in our breeding efforts will help to select crops resilient to abiotic and biotic environmental stresses and ultimately enable us to produce sufficient food in a more sustainable agriculture in the upcoming decades.Organic amendments can improve soil quality which has knock-on environmental and agronomic benefits. However, the use of new and emerging organic amendments such as biochar and brown coal waste (BCW) in soil systems requires continuous holistic assessments for robust consensus building in their environmental and agricultural applications. To examine the application of BCW and woodchip biochar (BIO) in agroecosystems, secondary data from literature on environmental (soil, air and water) aspects were compiled with primary agronomic data from a 3-year multicropping field trial and collated with supplementary data on economic factors (e.g. cost and availability). For the field trial, replicated plots were amended with FYM (for comparative reasons), BCW and BIO at 30, 24.2 and 12.8 for t ha\uffe2\uff80\uff931, respectively, with and without NPK and cultivated in a cropping sequence of maize, potato and barley. At the end of each season, soils were characterised for pH, cation exchange capacity (CEC) and fertility (macronutrient contents) in addition to nutrient uptake, nutritional quality and yield of crops. Compared with FYM, biochar and BCW were found to be associated with greater improvements in soil quality (e.g. building of soil structure and C sequestration) and knock-on water and air quality benefits mainly facilitated via increased cation retention and humic-linked sorption which abated gaseous emission and mitigated nutrient and heavy metal leaching. These along with variable improvements in soil chemistry, fertility and nutrient uptake in the agronomic field trial accounted for increased mean crop yield across treatments (higher with NPK): FYM (32.7 and 71.7%), BCW (33.5 and 60.1%) and BIO (21.8 and 48.2%). Additionally, biochar and BCW have lower pollutant (e.g. heavy metals) contents and were found to provide additional sustainability and net abatement cost-benefits. While the agronomic benefits of biochar and BCW were slightly lower compared with that of FYM, their lower environmental footprints and associated sustainability benefits are clear advantages for their adoption in environmental and agricultural applications.1 300 millions).

Les options de gestion pr\u00e9sentant le plus grand potentiel d'att\u00e9nuation pour le riz ou les syst\u00e8mes de culture \u00e0 base de riz sont le travail de conservation, l'irrigation contr\u00f4l\u00e9e\u00a0; le remplacement de l'ur\u00e9e par du sulfate d'ammonium, l'application d'inhibiteurs d'azote (N), l'application d'engrais \u00e0 teneur r\u00e9duite en azote, la culture int\u00e9gr\u00e9e du riz, du poisson et du canard et l'application de biochar. Une r\u00e9duction de 15\u00a0% de l'application moyenne actuelle d'engrais azot\u00e9s synth\u00e9tiques pour le riz en Chine, soit 231 kg N ha\u22121, entra\u00eenerait une diminution de 12\u00a0% des \u00e9missions directes d'oxyde nitreux (N2O) dans le sol. L'application combin\u00e9e d'engrais chimiques et organiques, le travail de conservation, l'application de biochar et l'application r\u00e9duite d'azote sont des mesures possibles qui peuvent r\u00e9duire les \u00e9missions globales de GES des syst\u00e8mes de culture en montagne. Les apports d'engrais conventionnels pour les l\u00e9gumes de serre repr\u00e9sentent plus de 2 \u00e0 8 fois la demande optimale en nutriments des cultures. Une r\u00e9duction de 20 \u00e0 40\u00a0% de l'application d'engrais azot\u00e9s sur les cultures mara\u00eech\u00e8res peut r\u00e9duire les \u00e9missions de N2O de 32 \u00e0 121\u00a0%, sans avoir d'impact n\u00e9gatif sur le rendement. L'une des mesures d'att\u00e9nuation les plus importantes pour les prairies agricoles pourrait \u00eatre la conversion de terres cultiv\u00e9es \u00e0 faible rendement, en particulier sur les pentes, en terres arbustives ou en prairies, ce qui est \u00e9galement une option prometteuse pour r\u00e9duire l'\u00e9rosion des sols. En outre, l'exclusion du p\u00e2turage et la r\u00e9duction de l'intensit\u00e9 du p\u00e2turage peuvent augmenter la s\u00e9questration du COS et r\u00e9duire les \u00e9missions globales tout en am\u00e9liorant les prairies largement d\u00e9grad\u00e9es. Pour la production animale, o\u00f9 le fourrage de mauvaise qualit\u00e9 est couramment nourri, l'am\u00e9lioration de la gestion des p\u00e2turages et de la qualit\u00e9 de l'alimentation peut r\u00e9duire les \u00e9missions de m\u00e9thane (CH4) de 11\u00a0% et 5\u00a0% en moyenne.

These soils form the basis of agricultural production systems on which significant numbers of people depend upon for livelihoods. The objectives of this study were to investigate soil acidification following the introduction of Stylosanthes in cropping systems of a tropical semi-arid region. Most soils in Northeast Thailand are sandy and acidic (pH 4.0 in CaCl2) with high rate of drainage. Soil acidification was studied over a 6-year period on plots that had been treated either with or without lime additions under different cropping patterns. In the initial first 3 years, a rotation of maize and cowpea was compared to a bare soil treatment where no vegetation was allowed to establish. During the following 3 years, a rotation of maize and Stylosanthes was compared to a continuous Stylosanthes hamata (stylo) treatment. Total soil acidification was calculated from measured pH changes and pH buffer capacity. Acidification due to root system activity was estimated from the above ground biomass production and its ash alkalinity. In the limed systems, soil pH decrease was well correlated with the ash alkalinity of the crop and its removal from the plot. Acidification was highest in the bare soil (6.3 kmol H+ ha(-1) year(-1)), due to leaching of applied N fertilizers. The cowpea-maize rotations did not increase significantly the rate of acid addition (7.6 kmol H+ ha(-1) year(-1)), since the crop residues were returned to the plot. The introduction of stylo in the cropping system resulted in a lower net acidification rate when it was cultivated in rotation with maize (1.3 kmol H+ ha(-1) year(-1)), due to the lower rate of leaching. In contrast, continuous cultivation of stylo triggered accelerated acidification (7.2 kmol H+ ha(-1) year(-1)), as a result of the large quantities of biomass with high ash alkalinity being removed from the plot. In the no-lime system, the pH of the soil profile remained stable at pH 4.0 regardless of the cropping system, even though the acidification rates were quite similar to those in the limed treatments. This would suggest that the soil was strongly buffered at pH 4.0. XRD patterns showed that kaolinite, the main clay mineral, was more disordered and less crystalline in the surface horizons than at depth. It is suggested that the dissolution of kaolinite is responsible for the buffering of soil pH at 4.0. From the dissolution equation of kaolinite, it is expected that the amount of aluminium in the topsoil would increase along with the release silica that would accelerate cementation processes between soil particles resulting in further degradation.

Such information is needed to determine impacts on the global C cycle and the sustainability of agricultural systems that are replacing native forest. The aim of this study was to predict soil carbon stocks and changes in the Brazilian Amazon during the period between 2000 and 2030, using the GEFSOC soil carbon (C) modelling system. In order to do so, we devised current and future land use scenarios for the Brazilian Amazon, taking into account: (i) deforestation rates from the past three decades, (ii) census data on land use from 1940 to 2000, including the expansion and intensification of agriculture in the region, (iii) available information on management practices, primarily related to well managed pasture versus degraded pasture and conventional systems versus no-tillage systems for soybean ( Glycine max ) and (iv) FAO predictions on agricultural land use and land use changes for the years 2015 and 2030. The land use scenarios were integrated with spatially explicit soils data (SOTER database), climate, potential natural vegetation and land management units using the recently developed GEFSOC soil C modelling system. Results are presented in map, table and graph form for the entire Brazilian Amazon for the current situation (1990 and 2000) and the future (2015 and 2030). Results include soil organic C (SOC) stocks and SOC stock change rates estimated by three methods: (i) the Century ecosystem model, (ii) the Rothamsted C model and (iii) the intergovernmental panel on climate change (IPCC) method for assessing soil C at regional scale. In addition, we show estimated values of above and belowground biomass for native vegetation, pasture and soybean. The results on regional SOC stocks compare reasonably well with those based on mapping approaches. The GEFSOC system provided a means of efficiently handling complex interactions among biotic-edapho-climatic conditions (>363,000 combinations) in a very large area (\u223c500\u00a0Mha) such as the Brazilian Amazon. All of the methods used showed a decline in SOC stock for the period studied; Century and RothC simulated values for 2030 being about 7% lower than those in 1990. Values from Century and RothC (30,430 and 25,000\u00a0Tg for the 0\u201320\u00a0cm layer for the Brazilian Amazon region were higher than those obtained from the IPCC system (23,400\u00a0Tg in the 0\u201330\u00a0cm layer). Finally, our results can help understand the major biogeochemical cycles that influence soil fertility and help devise management strategies that enhance the sustainability of these areas and thus slow further deforestation.", "keywords": ["land use change", "2.

In silvoarable systems, trees are intercropped with arable crops, and in silvopastoral systems trees are combined with pasture for livestock. These systems may produce forage and timber as well as providing ecosystem services such as climate change mitigation. Carbon (C) is stored in the aboveground and belowground biomass of the trees, and the transfer of organic matter from the trees to the soil can increase soil organic carbon (SOC) stocks. Few studies have assessed the impact of agroforestry systems on carbon storage in soils in temperate climates, as most have been undertaken in tropical regions. This study assessed five silvoarable systems and one silvopastoral system in France. All sites had an agroforestry system with an adjacent, purely agricultural control plot. The land use management in the inter-rows in the agroforestry systems and in the control plots were identical. The age of the study sites ranged from 6 to 41 years after tree planting. Depending on the type of soil, the sampling depth ranged from 20 to 100 cm and SOC stocks were assessed using equivalent soil masses. The aboveground biomass of the trees was also measured at all sites. In the silvoarable systems, the mean organic carbon stock accumulation rate in the soil was 0.24 (0.09-0.46) Mg C ha(-1) yr(-1) at a depth of 30 cm and 0.65 (0.004-1.85) Mg C ha(-1) yr(-1) in the tree biomass. Increased SOC stocks were also found in deeper soil layers at two silvoarable sites. Young plantations stored additional SOC but mainly in the soil under the rows of trees, possibly as a result of the herbaceous vegetation growing in the rows. At the silvopastoral site, the SOC stock was significantly greater at a depth of 30-50 cm than in the control. Overall, this study showed the potential of agroforestry systems to store C in both soil and biomass in temperate regions.", "keywords": ["Juglans regia", "F08 - Syst\u00e8mes et modes de culture", "Lolium perenne", "culture associ\u00e9e", "adaptation aux changements climatiques", "01 natural sciences", "630", "http://aims.fao.org/aos/agrovoc/c_6455", "http://aims.fao.org/aos/agrovoc/c_3660", "syst\u00e8me sylvopastoral", "p\u00e2turages", "biomasse a\u00e9rienne des arbres", "[SDV.EE.ECO] Life Sciences [q-bio]/Ecology", " environment/Ecosystems", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_33798", "agroforesterie", "2.

A few studies have shown that Piliostigma reticulatum , a dominant native shrub in parklands from Senegal to Sudan, can positively impact crop yields. However, there are no experiments that measure whether this species can stabilize long-term crop productivity under erratic rainfall. Therefore, an 11-year study of an optimized P. reticulatum intercropping system (1000 shrubs ha \u22121 with annual coppiced residue soil amendments) was initiated in 2004 in Senegal, West Africa to determine its impacts on crop productivity and soil quality. The experiment was a split-plot factorial design with the main plot shrubs (with and without) and the subplot fertilizer rate (0, 0.5, 1, and 1.5 times the recommended N-P-K rate) with an annual groundnut ( Arachis hypogaea ) and pearl millet ( Pennisetum glaucum ) crop rotation. Yield, biomass, soil carbon, and soil and plant nutrient data from 2011 to 2015 were compared with data from 2004 to 2007. The presence of shrubs increased millet and groundnut yield from 2011 to 2015 and rainfall water use efficiency (WUE) between 2004 and 2015. Without fertilizer addition, the shrub plots had approximately 2 times greater millet yield throughout the duration of this experiment. The presence of shrubs also improved soil quality, as evidenced by significantly greater C in the fraction P. reticulatum intercropping promotes C sequestration. In addition, five macronutrients (N, K, Ca, Mg, S) and two micronutrients (Mn and Cu) were significantly greater in the shrub plots. The results provide strong evidence that intercropping with P. reticulatum is an ecological agroforestry system for the Sahel that can remediate soils, increase crop yields, and buffer climate change.", "keywords": ["580", "Pearl millet", "2.

We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as 'promising practices'; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or 'standard practice' (baseline). Relative effects were analysed through indicator response ratio (RR) under each paired practice. For this we considered data of 30 long-term experiments collected from 13 case study sites in Europe and China as collated in the framework of the EU-China funded iSQAPER project. These were complemented with data from 42 long-term experiments across China and 402 observations of long-term trials published in the literature. Out of these, we only considered experiments covering at least five years. The results show that OM addition favourably affected all the indicators under consideration. The most favourable effect was reported on earthworm numbers, followed by yield, SOM content and soil aggregate stability. For pH, effects depended on soil type; OM input favourably affected the pH of acidic soils, whereas no clear trend was observed under NT. NT generally led to increased aggregate stability and greater SOM content in upper soil horizons. However, the magnitude of the relative effects varied, e.g. with soil texture. No-tillage practices enhanced earthworm populations, but not where herbicides or pesticides were applied to combat weeds and pests. Overall, in this review, yield slightly decreased under NT. Crop rotation had a positive effect on SOM content and yield; rotation with ley very positively influenced earthworms' numbers. Overall, crop rotation had little impact on soil pH and aggregate stability \u2212 depending on the type of intercrop; alternatively, rotation of arable crops only resulted in adverse effects. A clear positive trend was observed for earthworm abundance under organic agriculture. Further, organic agriculture generally resulted in increased aggregate stability and greater SOM content.

We determined the soil nutrients, physicochemical properties, enzyme activities and microbes by high-throughput sequencing. We found that the intercropping system changed the bacterial community structure independently of the intercropping pattern. The bacterial community was characterized by a higher abundance of the phyla Proteobacteria and Bacteroidetes phyla and of the genus Pseudomonas, which are related to nutrient cycling, and by greater amounts of other beneficial microorganisms like Bacillus, Streptomyces and Sphingomonas. The intercropped systems significantly boosted the total nitrogen, available phosphorus and total organic carbon levels in addition to the melon yield. They also enhanced the acid phosphatase and \ufffd\ufffd-glucosidase activity compared to the melon monocrop.

Compared to an unfertilized control (CK), all fertilization treatments, including inorganic nitrogen fertilizer only (N), balanced inorganic fertilizers (NPK), NPK plus corn straw (SNPK), and NPK plus farmyard manure (MNPK), resulted in significant increases in corn yield. However, only organic matter amendments sustained increasing yield trends, with annual rates of 0.137 and 0.194tha\u22121 for the SPNK and MNPK treatments, respectively (P<0.05). During the 22years, the daily mean, maximum and minimum temperatures increased by 0.50, 0.53, and 0.46\u00b0C per decade, whereas precipitation displayed no significant change but showed large seasonal variation. According to a regression analysis, increased air temperature exerted positive effects on corn yields under the SNPK and the MNPK treatments. Under both treatments, soil organic carbon contents and soil nutrient availabilities increased significantly compared to their initial levels in 1990, whereas soil bulk density and total porosity changed slightly under the two treatments, which showed higher soil water storage than other treatments. In contrast, significant increases in soil bulk density and decreases in soil total porosity and soil nutrient availability were observed under the CK, N and NPK treatments. The contributions of soil fertility to corn yield were 28.4%, 37.9%, 38.4%, 39.0%, and 42.9% under CK, N, NPK, SNPK, and MNPK treatments, respectively, whereas climate changes accounted for 27.0%, 14.6%, 12.4%, 11.8%, and 10.8%.

The push\u2013pull technology concurrently addresses these constraints. It involves intercropping maize with stemborer repellent fodder legume, Desmodium spp. (push), with an attractant crop, Napier grass, Pennisetum purpureum (pull), planted around this intercrop, thus making it difficult to interplant edible legumes. We assessed farmers\u2019 practice and perceptions on intercropping and willingness to integrate beans in their push\u2013pull plots from a sample of 300 farmers in six districts in western Kenya. All the respondents traditionally intercropped maize with beans, planted either between the rows of maize, in the same holes with maize or in between maize plants within a row. The majority (92%) were willing to integrate beans in their push\u2013pull plots. We, therefore, evaluated effects of integrating beans in the maize\u2013desmodium intercrops. Treatments comprised a maize monocrop, maize\u2013bean intercrop and three maize\u2013desmodium intercrops, two of which were integrated with beans, either in the same holes with maize or in between maize plants in a row (bean integration plots). On-farm trials were similarly established among 56 farmers in four districts in western Kenya to assess the two integration methods. S. hermonthica counts and stemborer damage to maize were significantly lower and maize yields significantly higher in the maize\u2013desmodium and bean integration plots than in the other systems. Overall, integration of beans in the maize\u2013desmodium intercrops and the planting arrangement did not compromise the S. hermonthica and stemborer control efficacy of desmodium. Integration of beans significantly increased labour and total variable costs, with these being significantly higher in plots with both crops in different holes than in the same hole. Total revenue, gross benefits and benefit cost ratios did not significantly differ between the bean integration and maize\u2013desmodium intercrops. Furthermore, these parameters were for most part not affected by the planting arrangements, both on-station and on-farm. These results show that integration of beans in the maize\u2013desmodium and indeed push\u2013 pull technology while guaranteeing an additional crop, a protein source, to the farmers does not compromise the observed benefits of the technology but yields same economic benefits. Where labour is easily available, farmers are, however, advised to plant maize and beans in separate holes to avoid the risk of competition for moisture and nutrients where these might be limiting.", "keywords": ["580", "2.

These techniques consisted of using mixed cropping of maize with haricot beans at different maize:bean ratios and a \u2018\u2018push\u2013pull\u2019\u2019 (PP) strategy utilizing Napier grass as a trap plant around maize plots as the \u2018\u2018pull\u2019\u2019 and Desmodium in between maize rows as a deterrent or \u2018\u2018push\u2019\u2019. In Melkassa, pest infestations were too low for the cropping system to significantly affect pests, plant damage and yields while in Mieso, where the pest densities were high, intercropping of maize with beans at ratios of 1:1 to 2:1 significantly decreased borer densities compared to pure maize stands. Chilo partellus (Swinhoe) and Cotesia flavipes (Cameron) were the major stem borer and parasitoid species, respectively, recorded both at Melkassa and Mieso. Borer parasitism was higher at Mieso than at Melkassa and it tended to increase with the increase of haricot bean ratio in the intercropping system. Land equivalent ratios of >1 indicated higher land use efficiency in mixed compared to sole cropping, even if pest densities were low. Establishment of Desmodium and Napier grass in PP trials varied from site to site, and poor establishment was observed in plots with low soil pH. Where yields varied significantly, they were lower in the PP than the sole maize plots. Borer densities were low and mostly not affected by the cropping system. However, in the second season when borer density was relatively high, higher levels of infestation and leaf feeding scores were recorded in the control than push\u2013pull plots.

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. Consequently, intercrop reduced grapevine growth of the year but also the potential growth for the next year by decreasing grapevine nitrogen perennial reserves", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "P33 - Chimie et physique du sol", "2.

The contribution of catch crops to the ecological intensification of organic arable systems was investigated using data of a 12-year field experiment carried out at three sites in Denmark. This study focused on the yields of spring oats and spring barley in systems with and without manure in two different cropping systems (O2 and O4) that differed in the proportion of legume-based catch crops (O2 lower and O4 higher) and in the rotation composition (grass\u2013clover green manure in O2 and pulse crops in O4). Three consecutive four-year crop cycles were established at three locations representative of different soil types (loamy sand, sandy loam and coarse sand) and climatic conditions. Crop management and soil operations were performed following common practices in organic farming. Measurements of dry matter (DM) and N content of grain cereals at harvest, above-ground biomass in catch crops and green manure crops in autumn and of the green manure crop at the first cutting were performed. The effect of catch crops on grain yield varied with cereal and catch crop species, soil and rotation type, and the application of N in manure. Higher yield increases from previous catch crops were obtained for spring oat than for spring barley with mean estimates of the apparent N recovery efficiency of N in above-ground catch crops of 69% and 46%, respectively. However, lower autumn N in catch crops undersown in high yielding cash crop was also observed. For spring oats mean grain yield benefits of including catch crops varied from 0.2 to 2.4\u00a0Mg\u00a0DM\u00a0ha\u22121 depending on location, manure use and cycle of the rotation. In spring barley mean grain yield benefits from catch crops varied from 0.1 to 1.5\u00a0Mg\u00a0DM\u00a0ha\u22121. There was a tendency for the effect of catch crop on grain yield to increase over time. These results indicate that in Nordic climates catch crops can contribute to the ecological intensification of spring cereals, not only by reducing the nitrate leaching and increasing N retention, but also by improving yields.

An undersown crop can also compete with the main crop. Seventeen plant species were undersown in spring barley (Hordeum vulgare L.) to study their suitability regarding establishment, biomass production, competition with the main crop and effects on soil mineral N. 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. A mixture was optimal to reduce N leaching. Italian ryegrass is a very competitive species that should be undersown at moderate seeding rates to avoid large yield reduction in the main crop. Black medic (Medicago lupulina L.) slightly increased N leaching risk, but red clover (Trifolium pratense L.) and white clover (Trifolium repens L.) did not increase soil NO3-N content. As clovers did not compete strongly with the main crop, fairly high seeding rates can be used to maximise N fixation to benefit the successive crop. \u00a9 2007 Elsevier B.V.

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. The Tephrosia-coffee intercropping system offers great potential for agroecological intensification for smallholder farmers in the East African highlands.", "keywords": ["2.
