Dr. El Gharous received a Horticultural Engineer degree (B.Sc.) in 1980 from the Agronomy and Veterinary Hassan II Institute in Rabat, Morroco. He was hired by INRA in Morocco in 1980. Mohamed subsequently received his M.Sc. (Agronomy) in 1987 and his Ph D. (Soil Science) in 1994 — both from Oklahoma State University in Stillwater, USA. Dr. El Gharous’s research career began by examining soil fertility for cereals in arid and semi-arid regions. Selected research highlights include following the evolution of P and K in soils under wheat-fallow rotation and quantifying their residual effects; improving fertilizer recommendation techniques in calcareous soils of Morocco; exploring composting and compost effects on soil quality and plant nutrition; defining fertilizer formulas adapted to Moroccan soil and climatic conditions and crops; and adaptation and improvement of soil and plant analyses methods.
