Soil fertility management and water relationships

Data presented show the importance of selecting the proper variety for fertilizer response and nutrient sufficiency, and combining various other cultural practices having a positive effect on yield and water-use efficiency (WUE). Fertilizer and available water interact such that at some unestablished point, water becomes limiting and fertilizer applications will not increase yield or WUE. Water-conserving practices that increase available water by reducing runoff, increasing infiltration, and reducing evaporation can become economically feasible only when nutrient deficiencies are corrected. Research on the chemistry and fertility of soils is one of the key factors to increase and sustain crop production in Sahelian Africa
