Abstract: Biochars (BCs) suitability as a soil amendment depends strongly on its cation exchange capacity (CEC), which governs nutrient retention in acidic, weathered tropical soils. This study evaluated and compared the CEC and associated chemical properties (pH, organic matter, total N, P, and K) of biochar produced from ten locally available feedstocks: Rice Hull (BC1), Oil Palm Empty Fruit Bunch (BC2), Coconut Shell (BC3)
