Research Abstract

To evaluate soil water and nutrient dynamics and optimize "Fallow Band System", the agricultural practice developed by the author to control desertification and improve crop production, lysimeter experiment was conducted in the International Crops Research Institute for the Semi-Arid Tropics West and Central Africa. On the basis of the results on soil water and nutrient dynamics, the author revealed that the optimal interval between the fallow bands was about 30 m.
