ABSTRACT

Nutrient stock is the accumulation of nutrients via soil particles, sediments and atmospheric deposits. The study was carried out at university of Benin located in Ovia North East local government Area of Edo state. Soil samples were collected from each sport complex, project farm, Faculty of Agriculture arboretum and AGR305 farm in the University of Benin. The samples were prepared and analyzed for some soil physical and chemical properties using standard methods. Nutrient stock was determined by evaluating N,P,S content in the soil and the data obtained were fitted to modified nutrient stock formula of FAO. The results showed that the soils are predominantly sandy and acidic, with highest acidity obtained for arable land use, the nutrient stock capacity of the different land uses varies, with arable land use exhibiting highest nitrogen stock capacity of 2360 mg N/ha at 0-30 cm soil depth why highest P and S stock capacity was obtained in plantain field with mean values of 2354 mg P/ha and 164 mg S/ha respectively. At 30-60 cm soil depth highest N, P, S stock of 3890 mg N/ha, 971mg P/ha, and 433 mg S/ha was obtained for sport land, plantain field and forested land respectively. It could be concluded that at 0-30 cm soil depth arable land has the highest N stock while plantain field has the highest P and S stock capacity.
