Overview

About this product

Hakaphos Violeta 13-40-13 — water-soluble complex fertilizer with a high phosphorus content: 40% P2O5, all of it water-soluble, 13% nitrogen (8.6% ammonium, 4.4% nitrate) and 13% K2O. The formula is recommended for crops during periods of marked phosphorus deficiency.

The fertilizer contains boron, copper, iron, manganese, molybdenum and zinc (the maker states chelated micronutrients) and is suitable for agricultural and horticultural crops. It dissolves quickly and completely, so it does not clog drippers and nozzles, but precipitation may occur with some water types.

The chloride content is low. 25 kg bag.
