Product Overview

Functional Soluble Fertilizer (19-19-19 + TE + biostimulants) is a multi-functional water-soluble product that combines balanced NPK nutrition, EDTA-chelated trace elements, and integrated bio-stimulants (seaweed extract + humic acid) in a single, 100% soluble formula. This product represents the next generation of fertigation technology — delivering not just nutrients but biological growth enhancement through every irrigation cycle. Designed for the most demanding protected cultivation and high-value crop applications where maximum return per square metre justifies premium inputs.

How Functional Soluble Fertilizer Works

The 19-19-19 balanced macro ratio ensures complete nutrition at any growth stage, while EDTA-chelated micronutrients (Fe, Zn, Mn, Cu, B, Mo) remain plant-available across a wide pH range (4-9). The integrated seaweed extract provides natural cytokinins for cell division and stress tolerance, while humic acid components improve nutrient chelation and root zone biology. This synergistic combination delivers 15-25% higher yield response compared to straight NPK soluble at the same nutrient rate — the bio-stimulant components amplify the efficiency of every nutrient gram applied.

Application Guide

Fertigation: dissolve 1-3 g/L in irrigation water, apply continuously or with each irrigation cycle. Foliar spray: dissolve 3-5 g/L, apply every 7-14 days. Hydroponics: use at 0.5-1.5 g/L as part of nutrient solution. Greenhouse vegetables: 3-5 kg/1000m²/week. Cut flowers: 2-3 kg/1000m²/week. Adjust concentration based on crop stage: lower during vegetative, higher during fruiting/flowering.

Ideal For

Greenhouse vegetablesCut flowers & ornamentalsHydroponic systemsHigh-tunnel productionNursery propagationDrip-irrigated horticulturePremium berry productionMedicinal herb cultivation

Storage & Handling

Store in sealed bags in cool, dry conditions. Highly hygroscopic — reseal immediately after opening. Shelf life: 18 months. Dissolve in clean water with gentle agitation. Use within 24 hours of preparing stock solution.

Why Choose Dongkwang Poland?

Our Functional Soluble uniquely integrates seaweed extract and humic acid directly into the NPK granule — not as a separate tank-mix additive. This ensures every drop of irrigation solution delivers both nutrients and bio-stimulants uniformly. The integrated approach eliminates mixing complexity and ensures consistent biological enhancement.
