Overview

About this product

Hakaphos Calcidic Plus N 19-6-6 — a water-soluble high-nitrogen compound fertilizer for fertigation. Of its 19% nitrogen, 13.5% is nitrate and 5.5% ammonium, and calcium is 14% CaO; the maker intends it for the early development stages of crops with a higher calcium need.

Phosphorus, 6% P2O5, is fully water-soluble, potassium is 6% K2O, and the maker states added chelated micronutrients. There is no sodium, chlorides are below 1%; the low pH improves the availability of phosphorus and micronutrients.

The solution does not clog drippers, but with some water types a precipitate is possible. Bag 25 kg.
