[ 1 ] - Nitrogen and Phosphorous Loss as Affected by Plough Direction in Rainfed Wheat Land of a Semi- Arid Region

Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi- arid soil is, however, limited. This study was carried out to investigate the effects of tillage direction on soil, water, nitrogen and phosp...
