Journal Title:Journal of Environmental Issues and Agriculture in Developing Countries

This study was carried out as a follow-up research from the 2015 cropping season at the Teaching and Research Farm of the University of Agriculture, Makurdi during the 2016 cropping season. The aim was to evaluate the residual effect of rice husk incorporation on the soil chemical properties. It involved the use of an experimental field previously applied with three rates of unburnt and four rates of burnt rice husk as soil amendment and the control, replicated three times in a Randomized Complete Block Design (RCBD) during the 2015 cropping season. Data was obtained on selected soil chemical and biological properties. They were analysed using standard laboratory procedures. Results indicated that the residual effect of rice husk improved soil chemical and biological properties in the succeeding growing season. It is recommended that burnt rice husk at 2.5 t/ha or 4 t/ha of unburnt rice husk could be applied to improve the soil chemical and organic matter content respectively for increased soil fertility in the study area.
