Outline of Final Research Achievements

For achieving food security in Sub-Sahara Africa, it is crucial to synchronize the soil nutrient supply pattern with the crop nutrient uptake pattern during a crop growth period. To attain this goal, a nutrient dynamics model incorporating temporal and spatial variations should be developed. In this project, we had conducted the field experiments in Niger, Tanzania, and Cameroon, which have various climate and soil conditions, from 2012 to 2015 and accumulated scientific knowledge about (1) soil organic matter dynamics, (2) temporal nutrient variation caused by fluctuation of soil microbial biomass, (3) spatial nutrient variation caused by soil erosion and nutrient leaching. Then, on the basis of these field data, we are developing a prototype of a nutrient dynamics model incorporating temporal and spatial variations which can be applicable to agroecosystems in Sub-Sahara Africa.
