Organic Grade Potassium Humic Acid Powder 60% for Agricultural Use

Product Introduction

1) It improves soil physical properties by optimizing aggregate structure, lowering soil density, and creating a looser, healthier soil environment.

2) It increases soil cation exchange capacity and nutrient-holding ability, helping to adsorb and exchange plant nutrients, extend fertilizer release, and enhance both nutrient and moisture retention.

3)It supports and stimulates the activity and reproduction of beneficial soil microorganisms.

4) It promotes the breakdown and detoxification of synthetic substances (such as pesticides) and naturally occurring harmful compounds in the soil.

5) It improves the soil’s buffering capacity and helps regulate and stabilize soil pH levels.

6) Its dark color enhances heat absorption, allowing earlier soil warming and earlier spring planting.

7) It directly influences cellular metabolism, boosts crop respiration and photosynthesis, and improves resistance to stress conditions such as drought, cold, and disease.

8) It gradually releases essential nutrients required for plant growth during decomposition.

9) It promotes root development, increases yields, improves crop quality, and enhances the sweetness of fruits and melons.

The use of potassium humate:

1)It can be applied as a base fertilizer or top dressing, using strip application, broadcasting, or hole application methods.

2) It is suitable for soil application or foliar spraying.

3)It is widely used for fruit trees, tea plants, citrus, grapes, strawberries, forestry plants, ornamental trees, melons, vegetables, rice, and many other crops.

4) Apply as a water-soluble solution for root irrigation, or spray the solution evenly on leaves and keep them moist.

Main Applications

1)The active functional groups present in potassium humate are capable of binding and retaining potassium ions, effectively reducing potassium leaching in sandy or highly permeable soils while also limiting potassium fixation in clay-rich soils. By stabilizing potassium in different soil types, potassium humate helps maintain potassium availability and improves overall nutrient efficiency.

2) Certain components of potassium humate consist of low-molecular-weight humic substances, such as fulvic acid, which can help dissolve potassium-bearing minerals including silicate minerals and potassium feldspar. Through gradual decomposition, these substances promote the release of potassium and increase the level of available potassium in the soil. Compared with conventional potassium fertilizers, potassium humate achieves a potassium utilization rate that is approximately 87%–95% higher, effectively enhancing fertilizer performance, improving crop yields, and contributing to better crop quality.

3)It integrates soil utilization with long-term soil maintenance, achieving a balance between rapid nutrient availability and sustained effectiveness. This product delivers outstanding water and nutrient retention performance while combining the benefits of both inorganic fertilizers and traditional organic manure, with overall performance superior to either. It offers excellent control over nutrient release, functioning as a highly efficient controlled-release fertilizer that prevents excessive nutrient supply at the early stage and nutrient deficiency at later stages, maintaining a stable nutrient release curve. In addition, the release behavior can be further adjusted through physical, chemical, and biological techniques, enabling both accelerated and prolonged nutrient release. As a result, fertilizer nutrient availability is closely aligned with crop nutrient requirements, ensuring a dynamic and balanced supply throughout the growing cycle.

4)Conventional chemical fertilizers often contribute to soil hardening as well as water and air pollution, whereas potassium humate can effectively avoid or greatly reduce these negative effects. It plays a significant role in increasing crop yields, enhancing product quality, improving nutritional value, lowering nitrate accumulation, and delivering better color, flavor, taste, and storage performance. As an environmentally friendly input, potassium humate serves as a fundamental material for clean agricultural production and green food systems. With low nutrient loss and high utilization efficiency, potassium humate is steadily absorbed by plants, resulting in simultaneous improvements in yield and quality. It is recognized as a “green” potassium fertilizer for agricultural use and a practical alternative to traditional potassium chloride and potassium sulfate. Potassium humate is suitable for all types of crops and can be applied either alone or in combination with conventional chemical fertilizers.
