Nitrogen is a macro nutrient that is essential to crop growth and production. One of the major constraints to sustainable crop production on the Jos Plateau is soil fertility. The availability of nitrogen and other essential plant nutrients in the soil is a key indicator of soil fertility. The content of nitrogen in soils is affected by a number of factors such as drainage, texture and slope steepness. This study was conducted on one of the important parent materials on the Jos Plateau, biotite-granite, taking into account the influence of topography and management practices by farmers. The result showed that the nitrogen content of the soils were quite low.
