A Pilot Scale Manufacture of Chemical Fertilizer Using Locally Sourced Materials in Benin-city, Edo State
2013Co-Authors: A C Igboanugo, J A IkimiAbstract:Some concerns have been expressed in the past regarding the appropriate technology for small scale blending of inorganic fertilizers in Nigeria. This paper reports on the progress made in this regard. Some samples of basic and raw materials were subjected to proximate analysis. Then, a sample of NPK (Nitrogen, Phosphorus and Potassium – 15:15:15) fertilizer which was produced with the materials on a pilot pan granulator proved to be potent on maize plant and compares favorably with the performance of commercial fertilizers. Whereas the median growth features obtained from the commercial NPK fertilizer were 29.3cm, 14.3cm and 14, representing features for height, stem size, and number of leaves respectively. The attributes of the correlates from homemade NPK fertilizer were 16.4cm, 2.2cm and 8cm respectively. The marked differences arise from the fact that the homemade fertilizer is less hygroscopic and as such takes some time to dissolve in the soil for the plant to take up, hence the perceived faltering or halting growth rate. However, towards the maturing age of the plants, observed readings noted were 162.0cm, 14.3cm and 14 respectively for commercial, and 154.0cm, 13.0cm and 14 respectively for the homemade NPK fertilizer, which are adjudged to be up to par. Remarkably, the Null Hypothesis Claim of no difference in median growth rate due to different fertilizers was accepted at a p-value of 0.05, implying that the potency of homemade NPK fertilizer is at par with that of the commercial.
