ANÁLISIS DEL EFECTO DE SECUENCIAS DE CULTIVO SOBRE EL ESCURRIMIENTO SUPERFICIAL Y PÉRDIDAS DE SUELO Y HERBICIDAS

Abstract

La evaluación del efecto de los sistemas agrícolas sobre el ambiente es fundamental para minimizar sus impactos negativos. Este estudio evalúa las pérdidas de agua, sedimentos y herbicidas por escurrimiento en distintas secuencias agrícolas, luego de una precipitación próxima a la pulverización. Fue realizado en parcelas de escurrimiento bajo lluvia natural, en INTA Paraná. Las secuencias de cultivo evaluadas fueron: soja continua (S), soja continua con trigo como cultivo de cobertura (CC-S) y trigo/soja (T/S) bajo siembra directa, las cuales fueron pulverizadas con glifosato y cletodim. Considerando el total de los datos analizados, los porcentajes perdidos en escurrimiento de glifosato y cletodim respecto a lo aplicado oscilaron entre 5,3-13,5% y 2,6-5,9%, respectivamente. Las pérdidas de suelo y AMPA (concentración) fueron mayores para S. Se resalta la importancia de las condiciones meteorológicas posteriores a las pulverizaciones para reducir el riesgo de aportes difusos de agroquímicos hacia cuerpos de agua.
