Evaluation of NPK-organo-zeolite as controlled release fertilizer for the growth of clinacanthus nutans
Sustainable environment can be achieved by controlling the release of fertilizer’s major nutrients (Nitrogen (N), phosphate (P) and potassium (K)) for the plants uptake since the leaching of these nutrients to the environment contributes to the soil and water pollutions. Therefore, this paper descri...
