Common inorganic fertilizers for Coconut Palms include those with balanced NPK ratios (Nitrogen, Phosphorus, Potassium) supplemented with micronutrients like magnesium, calcium, and sulfur. These fertilizers are often formulated as granules or soluble powders for easy application.

Application of Fertilizers

For Coconut Palms, fertilizer application is crucial to support growth and ensure better yields. Here’s a general guideline for fertilizing Coconut Palms per year:

Young Coconut Palms (1-3 years old):
- First Year: Apply a balanced fertilizer with a ratio of 8-3-9 NPK (Nitrogen-Phosphorus-Potassium) during the first year. Apply 100 grams per palm, four times a year (every three months).
- Second Year: Increase the fertilizer application to 200 grams per palm, four times a year. Adjust the NPK ratio based on soil and leaf nutrient analysis.
- Third Year: Continue with 300 grams per palm, four times a year. Monitor growth and adjust fertilization based on palm health and soil fertility.
Mature Coconut Palms (4 years and older):
- Annually: Apply approximately 500 grams of balanced fertilizer per palm per year. Adjust the timing of application based on regional climate and growing conditions.
- Nutrient Requirements: Ensure the fertilizer provides adequate nitrogen for leaf and stem growth, phosphorus for root development and fruit production, and potassium for overall palm vigor and disease resistance.

Best Practices for Fertilizer Application

Timing: Apply fertilizers during the rainy season or when irrigation is provided to ensure nutrients are readily available to the palms.
Placement: Spread fertilizers evenly around the base of the palm, avoiding direct contact with the trunk to prevent burning.
