NPK 5-20-30 — Mature Plantation PK Maintenance
Mature perennial plantations with established canopies need minimal nitrogen but continued P and K replenishment. NPK 5-20-30 at 55% total nutrients delivers 20% P2O5 and 30% K2O with just 5% N — preventing rank vegetative growth while maintaining production levels in tea, coffee and mature citrus. From 1,000 MT.

Perennial Maintenance
Tea gardens apply 5-20-30 at 100–150 kg/ha after each flush harvest to replenish P and K without stimulating excessive leaf growth that dilutes quality. Coffee plantations use 150–200 kg/ha post-harvest in biannual application cycles.
FAQ
Why only 5% N in a plantation fertilizer?
Mature trees and bushes recycle internal N and fix soil N through organic matter decomposition. Excess N reduces crop quality — lighter tea shoots, delayed coffee cherry ripening — while P and K remain the limiting nutrients.
Can 5-20-30 be used on young plantings?
No. Young plants in establishment phase need 12–15% N for canopy development. Transition to 5-20-30 after full canopy establishment, typically year 3–4 for tea and year 4–5 for coffee.
Does 5-20-30 improve tea quality?
By limiting N while supplying K, 5-20-30 promotes smaller, denser shoots with higher polyphenol content — preferred for premium orthodox tea production.
