Abstract

Due to the modifying properties of biochar, in recent years, the use of this substance has been considered with the aim of reducing soil erosion. The purpose of this study was to investigate the effects of biochar injection in the form of suspension on the chemical and physical characteristics of two types of soil sensitive to erosion. For this purpose, first, two types of biochar were produced and characterized, and then it was added to two types of soil prone to erosion in two levels in the form of aqueous suspension. The effect of adding biochar on the chemical and physical characteristics of loam, sand, and loam was investigated. The results obtained from this study showed that the addition of biochar in the form of an aqueous suspension can, in addition to preventing erosion-sensitive soil from touching, when adding biochar to the soil, improve the water permeability coefficient, and increase organic carbon, and soil granulation. So the use of both types of biochar increased the organic carbon of the studied soils. However, wood biochar showed a greater effect in this regard due to its higher carbon content. The use of both types of biochar in soil with a coarser texture (sandy loam) and higher water permeability decreased the soil water permeability. While the biochar obtained from wood increased the permeability coefficient of loam soil. In addition, the effect of biochar on increasing soil grain stability in loam soil was significant. In general, the effect of biochar addition on soil characteristics varies depending on the type of biochar used, the level of biochar addition, and the type of soil.
