To develop cost-effective, simple and reliable nutrient management systems to help farmers increase and stabilize crop yields in lowland and upland farming systems through improving knowledge of soils and water quality.
APPROACHES
Characterize soils and determine nutrient requirements for rice and upland crops
Continually revise and update recommended nutrient management practices
Develop suitable tools to aid nutrient management and research at the local level
Characterize relationships between soil types, cropping systems and supplementary irrigation and irrigation water quality
Integrate soil management strategies with other practices to develop whole-farm management packages
