Coconut fiber biochar alters physical and chemical properties in sandy soils

This work aimed to characterize the biochar produced from residues of coconut fruit and evaluate how it might beneficially alter retention capacity water nutrients in soils with a sandy texture. The was retort furnace later analyzed determine its chemical physical characteristics. Experiments analyze potential for were performed PVC columns filled 400 mm depth, upper 300 receiving treatments that consisted 0, 1, 2, 3, 4, 5% (p p-1) mixed soil. For nutrient experiment, addition concentrations, received same NPK fertilization. experiments completely randomized design four replications. mm, as well pH, effective cation exchange (ECEC) substrate, base saturation, concentrations P K, increased increasing concentration. Coconut demonstrated improving soils.
