Study on the sustainability of main cropping systems on degraded grey soils (Haplic acrisols) in the east-southern region
Soil samples were collected from different horizons of soil profile, 7-10 sites per cropping systems. Natural forest soil was the control. Results: haplic acrisols have poor chemical and physical properties. The most sustainable ecological indicators of sustainability for this soil are aggregate stability, bulk density, water retention capacity, CEC and soil organic matter content. Soil fertility declines in order: forest = sugarcane = rubber > cashew > cassava. Sugarcane cropping maintains productivity potential of the soil than other systems.
