Product Information

Potassium Humate is the potassium salt of humic acid, a high-efficiency organic potassium fertilizer and soil conditioner extracted from natural lignite, leonardite, or peat. It appears as black or jet-black shiny granules or powder, is soluble in water, and its solution is alkaline. It combines the multiple biological activities of humic acid with the nutritional function of potassium. It not only serves as a high-quality potassium source but also stimulates plant growth, improves soil structure, enhances fertilizer use efficiency, and increases crop stress resistance, making it a versatile green agricultural input.

Product Nature


  1. Physical Properties:
    · Appearance: Black or jet-black shiny granules, flakes, or powder
    · Solubility: Soluble in water, forming a soy-sauce-colored solution
    · Hygroscopicity: Highly hygroscopic

  2. Chemical & Biological Properties:
    · High Bioactivity: Contains various active functional groups (e.g., phenolic hydroxyl, carboxyl) that stimulate plant enzyme activity, promoting root development and seed germination.
    · Ion Exchange & Adsorption: Possesses a large specific surface area and high Cation Exchange Capacity (CEC), enabling it to adsorb nutrients and reduce leaching.
    · Chelation: Can form soluble chelates with trace elements (e.g., Fe, Zn, Mn) in the soil, enhancing their availability.
    · pH Buffering: Exhibits a certain buffering capacity towards soil pH.

Product Usage


  1. High-Efficiency Potassium Fertilizer: Serves as an organic potassium source, providing readily available potassium nutrition, especially suitable for chlorine-sensitive crops and during fruit enlargement/coloring stages.

  2. Growth Stimulant: Used for seed soaking, root dipping, irrigation, or foliar spraying to stimulate root growth and enhance the plant's ability to absorb water and nutrients.

  3. Soil Conditioner: When applied to soil, it promotes aggregate formation, alleviates compaction, improves saline-alkali land, and enhances soil nutrient and water retention.

  4. Fertilizer Synergist: When mixed or applied in combination with chemical fertilizers (especially urea and phosphate fertilizers), it reduces nitrogen volatilization and phosphorus fixation, thereby improving fertilizer use efficiency.

  5. Stress Resistance Enhancer: Improves crop resistance to abiotic stresses like drought, low temperature, and biotic stresses like pests and diseases.

Safety Matters


  1. Health Hazards:
    · Low toxicity, basically harmless to humans.
    · Dust may cause mild respiratory irritation.

  2. Handling Protection:
    · Wear a dust mask during handling to avoid significant dust inhalation.
    · Wash hands thoroughly after handling.

  3. Storage & Transportation:
    · Store in a cool, dry, well-ventilated warehouse. Strictly protect from moisture. Ensure the inner liner is tightly sealed due to its high hygroscopicity.
    · Store separately from food and feed.

  4. Application Technique:
    · Can be used as base fertilizer, top-dressing, for seed soaking, or foliar spray. Incorporate into soil when used as base fertilizer.
    · For foliar spray, use at the recommended concentration and avoid application under strong sunlight.
    · If tank-mixing with acidic pesticides, conduct a small-scale jar test first for compatibility.

  5. Environmental Safety:
    · An environmentally friendly product. Proper use poses no harm to soil or water bodies.
