- W2893588891 abstract "espanolRESUMEN En la presente investigacion se evaluo el efecto del sistema aereo de cuatro cultivos, tres de escarda (Zea mays L., Phaseolus vulgaris L. y Cucurbita pepo L.) y uno denso (Avena sativa L.) sobre la perdida de suelo y escurrimiento superficial mediante lluvia simulada. La unidad de muestreo fueron 16 lotes de 1m2 en el campo experimental de lomas de San Juan, de la Universidad Autonoma de Chapingo, Chapingo, Estado de Mexico. El suelo Entisol migajon-arenoso, profundidad de 40cm y pendiente de 2%. El crecimiento de la cobertura vegetal se cuantifico a traves de fotografias digitales cada 15 dias a partir de la siembra, captando la imagen multitemporal y suelo desnudo. El uso de coberturas vegetales manifiesta una relacion exponencial negativa respecto a la perdida de suelo; de los cultivos considerados en relacion a la perdida de suelo para reducir el proceso erosivo fue mayor en cebada > calabacita > frijol > maiz; la mejor correlacion cobertura vegetal y reduccion de la perdida fue del cultivo de frijol seguido por calabacita, maiz y avena. EnglishABSTRACT In this research the effect of air system four crops, three of weeding (Zea mays L., Phaseolus vulgaris L. and Cucurbita pepo L.) and one dense (Avena sativa L.) on soil loss and runoff was assessed simulated surface by rain. The sampling unit were 16 lots of 1m2 experimental field in the hills of San Juan, of the Autonomous University of Chapingo, Chapingo, State of Mexico. Entisol soil loam-sandy, depth of 40cm and slope of 2%. The growth of plant cover was quantified through digital photos every 15 days after planting, the multitemporal image capturing and bare soil. The use of mulches shows a negative exponential relationship to soil loss; of crops considered in relation to the loss of soil to reduce erosion process was higher in barley> squash> bean> corn; the best correlation vegetation cover and loss reduction bean crop was followed by squash, corn and oats." @default.
