Studying The Effect Of Adding Biochar On Some Physical And Chemical Properties Of Sandy Soil

Abstract

Sandy soils are abundant and widely used for agricultural practices; however, they are infertile and lack soil structure. Thus, sandy soils cannot retain nutrients and water. For the present research, an attempt has been made to examine the effect of biochar on physical dan chemical properties of sandy soil. Dua, empat, dan enam persen lahan ditambah dengan biochar dalam kondisi kontrol. Physical properties include bulk density, porosity, dan water retention, while chemical properties include pH, organic carbon, dan nutrient content (nitrogen, phosphorus, and potassium). The result of the experiment revealed that the application of biochar significantly decreased bulk density tanah, while at the same time increasing porosity and water retention. Moreover, biochar application resulted in improved soil chemical properties including increased soil pH value towards neutralization, soil organic carbon, and soil nutrients content. The observed effects were dose-dependent since the improvements increased with the rate of biochar application. Statistical analysis demonstrated that the differences between various rates of biochar application were significant. It is clear that incorporating biochar into sandy soil could be an ideal soil amendment.
