Biography

Lecturer /Researcher at Adeyemi College of Education, Ondo. I lecture in the field of Soil Science and crop production such as principles of Soil Science, Soil Fertility Management and Conservation, Soil Morphology, Principles of Arable Crop Production and Horticulture . My research focus is integrated soil and plant nutrition management around the efficient use of low level of mineral fertilizers with low level of organic manures in order to reduce the problems associated with the sole use of mineral and organic fertilizers for soil health and optimum crop production. I also specialize in soil and data analyses, fertilizer formulations and recommendations.

My Ph.D. thesis centers on Soil Science titled Effect of cocoa pod ash, poultry manure NPK fertilizer and their combinations on soil chemical properties, nutrient uptake and maize yield. University of Agriculture, Abeokuta. Ogun State, Nigeria. 177pp. Ability to form and lead team in research and field crop management. At present, I am the Head of the College Farm Services of Adeyemi College of Education.
