| Abstract | This study investigated the chemical properties of durian shell biochar which is used as a soil amendment. It can act as a carbon sink and as a means to improve crop yield. Plant nutrient elements in this biochar are in crystalline minerals located within the complex pore structure therefore biochar production from wastes could be a very good way to reduce demand for fertilizers. XRD and SEM-EDS results demonstrate that the numerous minerals in biochar are highly soluble, such as archerite (KH2PO4), chlorocalcite (KCaCl3 ), kalicinite (KHCO3), and sylvite (KCl) with small amounts of poorly soluble minerals (calcite CaCO3 and struvite KMgPO4.6H2O). When biochar is applied to soils at the recommended rates of tons per hectare, it will be a significant source of potassium, phosphorus and other nutrient elements. The availability of nutrients to plants will depend on properties of the biochar and the adjacent soil. |
