Soil management under no-tillage systems in the tropics with special reference to Brazil,-humid tropics. Compared to conventional tillage (tillage operations resulting in < 30% cover of plant residue remaining on the surface), no-tillage combined with crop rotation involving cover crops increases soil organic matter content, whilst improving soil fertility.

Soil organic carbon (SOC) management for sustainable productivity of cropping and agro-forestry sysultural systems has resulted in widespread agro-ecosystems with high soil organic carbon and nutrient depletion.
