Field experiments were conducted to examine the effect of tillage practices on sediment and nutrient loss and soybean growth under natural rainfall conditions.Three tillage practices were applied : down slope ridge (check),down slope ridge+contour living hedgerow,and cross ridge.Cross ridge tillage reduced surface runoff by 69% andsedimentyieldby86%,comparedtothechecktreatment.Thedownsloperidgewithacontourliv鄄 inghedgerowreducedsurfacerunoffby24% andsedimentyieldby53%.Additionally,comparedtothecheck plot,nutrientlossescarriedbyrunoffwerereducedbyover68% andthatcarriedinthesedimentwasreduced morethan85% in the cross ridge plot.Nutrient losses in runoff were reduced by 20% to 30% in the downsloperidgeandcontourlivinghedgerowplotandthosecarriedinthesedimentwerereducedby44% to 57%.Crossridgetillagesoybeanyieldsexceededthoseofthedownsloperidgeanddownsloperidge+contour livinghedgerowtreatmentsby16% 18%.Crossridgetillagecouldcontributetothepreventionsedimentand nutrientlossandcouldimprovecropyield,andthusitisrecommendedtobeappliedtomildslopesinthered soilregion.
