Electrical Circuits and Simulation Results,such as N rate, mode of N fertilizer application and choice of N sources for different agroecological zones of West Africa are discussed in relation to crop yield response. The interactive effects of cropping density and rainfall on N efficiency and yield are examined with particular emphasis on pro

Electrical Circuits and Simulation Results,ials currently available in the region will lead to increased incidence of sulfur (S) deficiency. In order to determine the S fertilizer requirements of major cereal crops, and compare the fate and efficiency of alternative S sources, experiments were conducted at six sites in semiarid and subhumid

M. Jeroen Fonderie,Johan H. Huijsinge systems such as bush fallow rotations, grass fallow systems (which are in many cases combined with trees) and planted fallow systems have proved to be very effective and can be modified in the context of today’s needs and circumstances to reduce nutrient losses, prevent nutrient imbalance, restitu

M. Jeroen Fonderie,Johan H. Huijsingng efficient use of fertilizers. Although several constraints limit the usefulness of fertilizers, progress has been made through careful experimentation in identifying and removing these constraints. In West Africa, sustainable agriculture is impossible in the absence of fertilizers because of the
