Food insecurity, waste disposal, soil degradation and low agricultural productivity remain major challenges in Nigeria. This work was carried out to evaluate the characteristics of fermented Rice Hull-Bokashi (RH-B) and its effects on soil and pepper (Capsicum spp.) performance. The fermentation pro...
