Fertilization
NPK Fertilization Plan
Balanced macronutrient program based on soil test results.
A fertilization plan should follow a soil test, not guesswork — applying nutrients a field already has wastes money and can worsen imbalances like locked-up micronutrients from over-fertilized phosphorus.
Step-by-step protocol
- Take a composite soil sample at 0–20 cm; test N, P, K, pH and organic matter.
- Apply base dressing of 20-10-10 at 300 kg/ha at planting.
- Side-dress with urea at 100 kg/ha at 30 and 60 days after emergence.
- Add potassium sulfate at 80 kg/ha before flowering for fruit crops.
Frequently asked questions
How often should I re-test soil?
Annually for actively farmed fields is standard, since nutrient levels shift with each season's crop, fertilization and rainfall.
What if I can't get a soil test done in time?
Visual deficiency symptoms — like uniform yellowing on older leaves for nitrogen — can guide an interim fertilization decision, but should be confirmed with a soil test as soon as possible.
