    In recent times the use of biochar as soil amendment has been proposed as one of the ways to retain cations and anions in soils. Sawdust and rice husk pyrolysed at 400°C, were used as amendments to investigate their retention capacities for NO₃⁻ and NH₄⁺ and subsequent enhancement of nitrogen (N) uptake in two sandy soils, Keta series (Quartz Psamment) and Nyankpala series (Plinthic Acrisol). The soils were amended with each biochar at 0, 20 and 40 t/ha and fertilized with cow dung and ammonium sulphate at 265 N kg/ha and maize was grown for 5 weeks. During the growth period the treated soils were leached with deioni ... 전체 초록 보기
