Therefore, there is bound to be a steady utilisation of nutrients by the tree and consequent depletion of the same in the soil. The average annual loss of the important nutrient elements has been estimated to be 56.2 kg. nitrogen, 13.0 kg. phosphorus 70.9 kg. potassium, 34.3 kg. calcium and 12.6 kg. magnesium from a hectare of land carrying 175 coconut palms. This data clearly indicate that there is large depletion of potassium and nitrogen and lesser depletion of calcium, magnesium and phosphorus from coconut gardens-When soil is depleted of the essential nutrient elements, naturally, coconut palms growing on such soils tend to show signs of hunger, which are manifested in different ways.encoconutAIDS diagnosisnutrient deficiencyArticle
