Abstract :
Upland soils in Indonesia have great potential for the future development of agriculture. However,most of these soils have low inherent fertitly and many have become degraded,especially those in sloping areas. A single heavy applicatian of rock phosphate (1 mt/ha) followed by the planting of a fast-growing leguminous cover crop (Mucuna sp.) resulted in improved productivity of imperata grassland, with significant residual effects that lasted three years. Bench terraces, ridges, and alley cropping systems were
