Abstract

There is need to evaluate the fertility status of soils for sustainable soil management and productivity. The fertility capability of soils in two agro-ecological zones of Nigeria was evaluated. This is with the view of identifying limitations and management problems in terms of the nutrient supplying capacity of the soils. Seven soil pedons were identified in Ado-Ekiti (dry upland rainforest) and nine in Kabba (southern guinea savannah) in a 12 hectares land each. Soils samples were collected at the top and subsoil and analyzed for physical and chemical properties. The soils were predominantly loamy textured at the surface and loam to sand and clay textured at the subsurface. Major limitations observed at Kabba are high gravel percentage, (r+) and anaerobic condition (g+) while low nutrient capital K was observed at Ado-Ekiti. Low buffering capacity (e) and ustic moisture regime are limitations common to both locations. Management practices suggested include the utilization of wetland areas for rice production, application of fertilizer in split doses and adoption of legumes into crop production.
