Sustainability of soybean-based cropping systems on a Vertic Inceptisol: 1. Effects of management on runoff, soil erosion, soil fertility and crop yields uri icon

abstract

  • Effects of improved versus traditional management of a Vertic Inceptisol on the productivity and resource use of two soybean-based cropping systems was studied from 1995 to 2003. Improved management comprised of sowing on broadbed-and-furrow landform and additions of nutrients through composted crop residues and prunings of Gliricidia (Gliricidia sepium (L.)); while traditional management consisted of sowing on flat landform and no addition of organic sources of nutrients. These management treatments were applied on both the shallow and medium-deep phases of an operational scale watershed. Cropping systems evaluated were soybean-chickpea sequential (SB-CP) and soybean/pigeonpea intercrop (SB/PP) systems
