Philippine Coconut Authority surveys indicated that there are ten distinct classes of coconut nutritional deficiency in the Philippines. Coconut areas maybe deficient in N, P, K, Cl, S and Mg but most provinces in the country fall under N-Cl deficiency.
Proper application of fertilizers increases nut and copra yield by as much as 230%. A study in Davao City
showed that with fertilizer application, a coconut farmer can realize a net income of about 180% compared to without fertilization.
