- Joker is a concentrated liquid organic fertilizer based on humic and fulvic acids, designed to improve soil properties and agricultural efficiency. It increases the soil's ability to hold nutrients and reduces leaching losses, so plants make better use of applied fertilizers.
- Joker contains potassium to support vital plant processes, plus chelated iron to help maintain micronutrient balance in the soil. It is used as a supporting input in fertilization programs, especially in poor soils or soils affected by salinity or environmental stress.
Key Features
- Contains 12% humic acid to improve soil structure and increase cation exchange capacity (CEC).
- Contains 3% fulvic acid to enhance nutrient uptake.
- Supplies potassium (K₂O) to support plant growth and crop quality.
- Contains chelated iron (EDTA) to help reduce iron-deficiency symptoms.
- Reduces nutrient leaching, especially in sandy soils.
- Improves the efficiency of fertilizers applied through irrigation.
- Suitable for all irrigation systems (drip, sprinkler, flood).
