 en Influence of Locally Sourced Additives on Neem Plant Organic Fertilizer Quality in Samaru, Zaria, Kaduna State, Nigeria


Neem samples (Neem fruit, Neem Cake and oil) were prepared using locally sourced materials, the Neem oil was obtained during the caking, while the Neem fruit was simply air-dried. The results showed that all the Neem samples contained: Nitrogen, Phosphorous and Potassium considerable for fertilizer production but Neem fruit has the highest percentage of Nitrogen 3.3%, Phosphorous 4.1% and potassium 3.8% while the oil has the least content of 1.1% Nitrogen, 2.0% Phosphorous and 1.1% potassium. Additives were introduced in the production to enhance the quality of the fertilizer such as limestone to neutralize the soil, poultry liter as supplement of the nitrogen, phosphorous and potassium content of the fertilizer, Rock phosphate to standardize the phosphorous content of the soil and to retain the soil texture and composition.
