“…Such effects were tested in two different soil types, a sandy soil and a clay loam (Bergeron et al 2011). The hypothesis was found to be true in two separate studies, where N losses could be significantly reduced in a clay loam (Bergeron et al 2011;Wang et al 2011), but not in a sandy soil where leaching rates exceeded N uptake; although sodium leaching was reduced where tree roots were present (Bergeron et al 2011). Apart from a deeper root system, reduced N inputs and reduced lateral surface flow reduce N losses in agroforestry systems (Wang et al 2011).…”

“…However, on the basis of findings of other effects of multiple-crop systems on the plant-soil system and biotic functions in soil structural dynamics, such effects can be hypothesised. Indirect evidence is also apparent from studies into intercropping effects on soil erosion processes and OM inputs, especially in agroforestry systems, where significant reductions in run-off rates and the risk of soil erosion have been reported (Wang et al 2011). Cultural management practices affecting soil structure do not necessarily differ between conventional and multiplecrop systems.…”

“…By intercropping trees and by increasing soil cover and root presence in the topsoil; run-off rates, the risk of soil erosion, salinity and nitrate leaching are reduced (Wang et al 2011;George et al 2012), while key nutrients are being restored (Altieri 1999;Whitmore and Schröder 2007). Further, agroforestry systems sequester more carbon through crop stands and affect organic matter inputs (Malézieux et al 2009;Oelbermann and Echarte 2011;George et al 2012).…”

Os componentes arbóreos das agroflorestas podem aumentar, consideravelmente, o consumo de água das chuvas, em comparação aos cultivos anuais (Lott et al, 2003), mas também promovem maior retenção de água em subsuperfície, no solo (Wang et al, 2011), e aumentam o potencial de sequestro de carbono (Albrecht & Kandji, 2003). As árvores podem contribuir para melhoria local das condições de cultivo e desenvolvimento de outras espécies, o que influencia a produtividade do sistema (Yang et al, 2009) e pode aumentar a rentabilidade do empreendimento consorciado, em comparação ao monocultivo (Ogol et al, 1999).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito das árvores de pau-branco (Cordia oncocalyx) sobre parâmetros fisiológicos, altura e biomassa do milho, em diferentes distâncias das árvores, em sistema agrossilvipastoril. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro tratamentos (distâncias do caule das árvores de 1, 2, 3 e 4 m), além do controle (plantas do cultivo tradicional), e cinco repetições. Cada parcela consistiu de uma árvore de pau-branco, ao centro, e linhas de milho plantadas nas quatro distâncias avaliadas do caule. As medidas fisiológicas e a produção de matéria seca foram registradas aos 30, 60 e 90 dias após o semeio do milho. As plantas sob a copa do pau-branco, a 1 e 2 m do caule, tiveram suas trocas gasosas, altura e produção de matéria seca afetadas pelas árvores. As plantas cultivadas a 3 m do caule tiveram desempenho semelhante ao observado no cultivo tradicional, e as cultivadas a 4 m apresentaram maior fotossíntese, condutância estomática, transpiração, altura e produção de matéria seca. As plantas de milho sob a copa são afetadas negativamente pelo sombreamento das árvores, enquanto as plantas fora da copa podem se beneficiar da presença das árvores no sistema.Termos para indexação: Cordia oncocalyx, Zea mays, agrossilvicultura, cultivo consorciado, integração lavoura-pecuária-floresta, sistemas agroflorestais. Development of maize under influence of "pau-branco" trees in an agrosilvopastoral systemAbstract -The objective of this work was to evaluate the effect of "pau-branco" (Cordia oncocalyx) trees on physiological parameters, height, and biomass of maize at different distances from the trees in an agrosilvipastoral system. The experimental design was a randomized complete block with four treatments (distances from trees of 1, 2, 3, and 4 m), besides a control (plants cultivated in the traditional system), and five replicates. The plots consisted of one "pau-branco" tree at the center, and maize rows planted at the four evaluated distances from the tree stem. Physiological measurements and dry matter production were recorded at 30, 60, and 90 days after the sowing of maize. The plants under the canopy of "pau-branco" -at 1 and 2 m from the stem -had their gas exchange, height, and dry matter production affected by the trees. The plants 3 m away from the stem had similar performance to those in the traditional system, and the plants at 4 m of distance had higher photosynthesis, stomatal conductance, transpiration, height, and dry mass production. Maize plants under the canopy are negatively affected by tree shading, whereas plants outside the canopy can be favored by the presence of trees in the system.

“…The correspondence between measured and simulated percolation fluxes during both early and entire growing periods is very good. The difference between simulated and observed values may be caused by macro-pores, earthworm burrows, roots, soil cracks, and lateral leakage (Akay et al, 2008;Janssen and Lennartz, 2009;Sander and Gerke, 2009;Wang et al, 2011).…”

a b s t r a c tIn the recent decade, increasing costs of labor, water, and fertilizers around the world led to a change in the method of crop establishment from traditional transplanted rice (TPR) to direct-seeded rice (DSR) and to a substantial rise in the DSR-managed area. Since water management in areas with DSR is quite different from those with TPR, vertical water movement and water and nutrient losses during the crop season may be different as well. Water flow and water losses in a DSR field in the Taihu Lake Basin of east China were monitored and evaluated using Hydrus-1D during two seasons with different rainfalls and irrigation managements.
