Why phosphorus and organic matter matter
Rubber is a long-lived plantation crop. Phosphorus supports root development in young plants, and organic matter helps soil hold moisture and nutrients through the dry months.
Published recommendations for rubber

These are general published recommendations for the crop, quoted as the source gives them. They are not FAMCO product doses. Follow a soil test and your local agriculture or horticulture office.
