Potassium Humate Fertilizer for Agriculture

Potassium humate is a high molecular weight, heterogeneous aromatic hydroxy carboxylate that appears as black granules or powdery solids. Extracted from lignite after fine selection and reaction with KOH solution, it is soluble in water and has an alkaline nature. This compound contains active functional groups such as carboxyl and phenolic hydroxyl groups.

As an efficient organic potassium fertilizer, potassium humate acts as a bioactive agent that increases the available potassium content in the soil. It helps reduce potassium loss and enhances the absorption and utilization of potassium by crops. The benefits include soil improvement, promotion of crop growth, and improved resistance to stress, ultimately enhancing crop quality. Additionally, it plays a role in protecting the agricultural ecological environment.

When mixed with urea, phosphate fertilizers, potassium fertilizers, and trace elements, potassium humate can create high-efficiency multifunctional compound organic fertilizers. Furthermore, it serves as a treatment agent for petroleum drilling fluids, primarily preventing wellbore collapse.

Features of Potassium Humate

1. Potassium humate can improve the physical characteristics of soil. It enhances soil aggregate structure and reduces soil compaction, achieving a good condition.

2. It increases the soil’s cation exchange capacity and nutrient retention ability. This helps in adsorbing and exchanging plant nutrients. It also enhances the slow-release effect of fertilizers and increases the soil’s ability to retain nutrients and moisture.

3. It provides activity for beneficial microorganisms in the soil.

4. It promotes the decomposition of synthetic substances (such as pesticides) or natural toxic materials and their effects.

5. It increases the buffering capacity of the soil and neutralizes soil pH.

6. Its black color helps absorb heat and allows for earlier spring planting.

7. It directly affects cellular metabolic processes. It enhances crop respiration and photosynthesis and strengthens the crops’ resilience to stress, such as drought, cold, and disease.

8. It releases essential nutrient elements for plants after decomposition.

9. It strengthens roots, increases yield, improves crop quality, and enhances the sweetness of fruits and vegetables.
