摘要：

This study deals with the influence of biochar use on sugarcane growth and nitrate-nitrogen percolation losses, as well as chemical and physical properties of Shimajiri maji soil. Two varieties of biochars, biosolids and bagasse (residues of sugarcane stalks after juice extraction), were mixed with Shimajiri maji soil. Changes in nitrate-nitrogen concentration in percolating water, specific gravity, and available soil moisture before sugarcane planting and after harvest were investigated. Indices of sugarcane growth (stem diameter and length), Brix, and yield of estimated available sugar in each plot were estimated. Results indicated that bagasse charcoal reduced soil dry density and increased available moisture of Shimajiri maji soil. Maintaining suitable soil water content increased yields and sugar content of sugarcane, while nitrate-nitrogen concentration in percolating water also decreased. Hence, bagasse charcoal use may reduce nitrogen loads in Shimajiri maji soil.
