   Abstract : To evaluate the effects of long-term application of organic and mineral fertilizers on maize yield and soil properties and further to investigate differences in soil fertility gradients, the Tropical Soil Biology and Fertility Institute of the International Centre for Tropical Agriculture (TSBF-CIAT) conducted an 8- year experiment on 12 farms in the districts Nyalgunga, Nyabeda and Vihiga in the Western Province of Kenya.
