Product Overview

Balanced Soluble Fertilizer (20-20-20 + TE) is the industry-standard all-purpose water-soluble NPK for fertigation and foliar applications. With 100% solubility, EDTA-chelated trace elements, and a perfectly balanced macro ratio, this product serves as the foundation of any precision fertigation program. It’s the go-to choice for mixed cropping systems, general-purpose greenhouse cultivation, and any situation where balanced nutrition is needed without specialised ratios. Over 10,000 tonnes shipped annually by Dongkwang Poland to greenhouse operations, nurseries, and high-tech farms across Europe, the Middle East, and Asia.

How Balanced Soluble Fertilizer Works

The 20-20-20 ratio delivers exactly equal proportions of N, P₂O₅, and K₂O — maintaining nutritional balance at any application rate. This makes it impossible to inadvertently over-supply one macronutrient relative to others. The EDTA-chelated micronutrients (Fe, Zn, Mn, Cu, B, Mo) are stable across pH 4-9, ensuring availability even in alkaline irrigation water. The EC contribution of 1.2 mS/cm per g/L allows precise salinity management through concentration control — critical for salt-sensitive crops and substrate cultivation.

Application Guide

Fertigation: dissolve 1-3 g/L depending on crop stage and EC target. Typical ranges: seedlings 0.5-1 g/L, vegetative 1-2 g/L, fruiting 2-3 g/L. Foliar: dissolve 3-5 g/L, apply every 7-14 days. Hydroponic: use as base nutrient at 1-2 g/L, supplement with calcium nitrate separately. Frequency: every irrigation cycle for continuous feeding or weekly for supplemental nutrition. Monitor runoff EC and adjust concentration accordingly.
