The effect of organic and inorganic sources of phosphorus (P) and P franctions and P fixation was studied on a red soil of Western Kenya. The Mexican sunflower (Tithonia diversifolia) proved to produce a high quality organic matter, capable of curbing phosphate fixation and making plant nutrients better available to the agricultural crops. It may, therefore, be considered as a promising complement to conventional mineral fertilisers.
The red soils of humid tropical Africa are notorious for fixing phosphorus, one of the key plant nutrients of agricultural crops. Farmers cannot afford full doses of expensive chemical fertilisers, therefore, they will welcome the Mexican sunflower as an important source of organic manure to meet crop nutrient requirements for sustainable agriculture.
