Potassium Humate Granular appears as black crystalline granules. The raw material is derived from naturally weathered lignite, soluble in water, and weakly alkaline. Through different proportions, humic acid and nutrients can be effectively combined to improve the utilization rate of fertilizer. It is a very ideal organic chelator, biological stimulator, and soil conditioner.
For Plant
• Effectively accelerate crop growth and development.
• Improve the nutrient uptake efficiency of crops through the leaf surface.
• Accelerate the synthesis of photosynthetic pigments and increase the photosynthetic rate.
• Increase crop yield and improve the quality of agricultural products.
• Activate the enzyme system of crops, accelerate the enzymatic reaction, promote
metabolism, and improve biological activity.
• Improve cytoplasmic concentration, affect the stomatal opening, and reduce respiration
and transpiration.
For Soil
• Enhance cation exchange capacity and improve soil water and fertilizer retention capacity.
• Enhance soil resistance, especially reduce the high salt content in alkaline soil.
• Promote nutrient absorption and increase soil humus content.
• Prevent soil from being polluted by heavy metal ions and other harmful substances.
• Improve fertilizer efficiency and enhance the utilization rate of nitrogen and phosphorus.
