- Joker is a concentrated liquid fertilizer based on natural organic acids (humic and fulvic acids) with potassium and Fe-EDTA chelated iron, designed to improve soil fertility and nutrient uptake. It revitalizes the soil, improves its chemical and biological structure, and helps plants make full use of available nutrients, especially in poor, saline or alkaline soils.
- Joker is applied with irrigation water to improve root performance, reduce nutrient leaching and raise the overall efficiency of fertilization programs.
Key Features
- Contains 12% humic acid to improve soil structure and increase cation exchange capacity (CEC).
- Contains 3% fulvic acid for faster, more efficient nutrient uptake.
- Supplies potassium (K₂O 5%) to support vital plant processes.
- Contains 0.5% Fe-EDTA chelated iron to help prevent iron-deficiency symptoms.
- Reduces nutrient leaching.
- Boosts biological activity and beneficial microorganisms in the soil.
- Suitable for all irrigation systems (drip, sprinkler, flood).
- Easy-to-mix, readily soluble liquid.
