Fertilizer Program

For a 5-Year Cultivation Cycle (Pre-Inoculation Phase)

Tree AgeTime (Months)Fertilizer TypeApplication RateNotes
0–3 monthsImmediately after plantingOrganic compost/vermicast1–2 kg per seedlingMix with topsoil during transplanting
Starter NPK (e.g., 16-20-0)1 tbsp/treeRepeat every 30 days
4–12 monthsQuarterlyChicken/goat manure2–3 kg/treeApply in a ring, 30 cm from base
MonthlyNPK 20-10-102 tbsp/treeSupports vegetative growth
1–2 yearsEvery 2 monthsNPK 14-14-14 or 10-10-103 tbsp/treeBalanced growth and root development
QuarterlyDolomite/lime (if acidic soil)100 g/treeRegulates pH for better nutrient uptake
Dry seasonMulch with dry leaves/rice husksPreserves soil moisture and adds organic matter
2–3 yearsEvery 2 monthsNPK 12-12-17-2 (with Mg)3–4 tbsp/treeBoosts woody growth, trunk diameter
QuarterlyK-rich organic blend (banana peel compost, ashes)1–2 kg/treePrepares tree for stress/resin induction
3–5 yearsEvery 2 monthsNPK 10-10-20 or 8-12-244–5 tbsp/treeIncreases K for heartwood development
Every 6 monthsSeaweed extract or foliar spray (trace elements)As per labelEnhances immunity & stress tolerance
Before inoculation1–2 months beforeReduce or stop nitrogen inputsAvoids excess leafy growth; encourages tree to enter defense mode

APPLICATION TIPS:

  • Apply early morning or late afternoon, preferably before rain.
  • Rotate chemical and organic sources to avoid soil nutrient fatigue.
  • Water well after applying chemical fertilizer to help absorption.
  • Increase fertilizer quantity as the tree ages, especially for high-density plantations.

Optional Add-ons for High-Performance Orchards:
