- Joker is a concentrated liquid fertilizer based on natural organic acids (humic and fulvic acids) with potassium and chelated iron EDTA, designed to improve soil fertility and increase nutrient absorption. It revitalizes the soil, improves its chemical and biological structure, and helps plants maximize the utilization of available nutrients, especially in poor or saline/alkaline soils.
- Joker is used with irrigation water to improve root performance, reduce nutrient loss through leaching, and increase the overall efficiency of fertilization programs.
Product Features
- It contains 12% humic acid to improve soil structure and increase cation exchange capacity (CEC).
- It contains 3% fulvic acid to increase the speed and efficiency of nutrient absorption.
- Provides potassium (K₂O 5%) to support vital processes within the plant.
- Contains 0.5% chelated iron EDTA to help prevent symptoms of iron deficiency.
- Washing reduces nutrient loss
- It improves the biological activity and microorganisms in the soil.
- Suitable for all irrigation systems (drip - sprinkler - flood)
- Liquid fertilizer that is easy to mix and dissolve
