(2015) Effect of Rice Husk as an Amendment On The Physico-Chemical Properties of Sandy-Loam Soil In Lafia, Southern-Guinea Savannah, Nigeriahttps://keffi.nsuk.edu.ng/handle/20.500.14448/2972Soil physical and chemical properties are important phenomena in agriculture, hydrological, ecological and environmental processes that affect the productive capacity of the soil. This study was conducted at the Nasarawa State University, Faculty of Agriculture Demonstration Farm, Shabu-Lafia, Nasrawa State, Nigeria to determine the effect of rice husk on physiochemical properties of sandy-loam soil. Four treatments were laid out in a Randomized Complete Block Design (RCBD) with three replicates. The treatment were RH0 (Control), RH2 (2 t/ha), RH4 (4 t/ha) and RH6 (6 t/ha). Soil samples were collected from the top soil depth (0 - 30 cm) before and after treatments for the determination of selected soil physical properties (particle size, bulk density and total porosity) and chemical properties (soil pH, organic matter, total nitrogen, available phosphorus, exchangeable bases and cation exchange capacity). The results indicated that increasing rice husk from 0 to 6 t/ha significantly increased soil pH, total porosity, organic matter, exchangeable bases (Mg2+, K+ and Na+) and cation exchange capacity between treatments in both seasons while bulk density and electrical conductivity decreased between treatments. Available P and exchange base, Ca2+ were not significant in the first season, however, became significant in the second season. Total nitrogen was not significant in both seasons. All physical and chemical properties showed improvement when the second season was compared to the first season. It can therefore, be concluded that application rate of 6 t/ha performed best with the highest improvement of the physical and chemical properties of the soil.enRice Husk, Soil Amendment, Soil Physical Properties, Soil Chemical Properties.Article
