Extensive studies have been conducted in the Nigerian savannas on nitrogen and phosphorus considered as most limiting nutrients for crop production, but not much on S nutrition, especially when in combination with organic manures. Organic manure is a good contributor of N in soils, though the amount of N contained in manure varies with source, quality of the substrate, age, management and ease of mineralization, therefore its co-application with readily soluble inorganic N and S becomes necessary and offers a realistic approach towards sustainable soil productivity, while at the same time improving the soil physical conditions for nutrient retention and uptake by plants.
