Organic fertilizers are derived from animal matter, animal human excreta, and vegetable matter. Naturally occurring organic fertilizers include animal wastes from meat processing, manure, slurry etc. This research was carried out to study the production, bio-safety and the chemistry of organic fertilizer from neem seeds, rice husk, blood meal, bone meal, and calcium carbonate; proximate analysis was carried out using standard procedures to determine the plant’s nutritive value of the formulated organic fertilizer for the presence of nitrogen by Khadjel distillation method, phosphorus by Bray No.1 method, Elements like Potassium and Nitrogen were confirmed Organic Carbon by Wakley- Black dichromate method and other micronutrients. Phosphorus is primarily used for the growth and repair of body cells and tissues. Potassium is required by plants to maintain the turgor pressure of the cell by keeping the cell strong. The result from the analysis indicated following based on the N.P.K content in each. Formulation 1 (N=4810mg/kg, P=4.76mg/kg, K=1166.7mg/kg), Formulation 2 (N= 7140mg/kg, P=19.83mg/kg, K = 1250mg/kg, Formulation 3 (N= 4060mg/kg, P=19.39mg/kg, K=600mg/kg), Formulation 4 (N=7700mg/kg,P=19.28mg/kg, K = 650mg/kg) and Formulation 5 ( N= 148400mg/kg,P= 20.10mg/kg, K=600mg/kg). The result shows that formulation 5 had the highest nitrogen content (N=148400mg/kg) while formulation 3 had the lowest nitrogen content (N=40600mg/kg) which is due to the increase in proportion of blood meal, poultry litters and neem seeds. This suggests that organic fertilizer could be a better substitute to conventional inorganic fertilizer as a soil conditioner and good plant manure when applied based on the soil nutrient requirements.
