Water Soluble Potassium Humate Granule is a water-soluble organic potassium fertilizer produced by reacting mineral-derived humic acid (mainly from weathered coal and lignite) with potassium hydroxide. It combines the biological activity of humic acid with the nutrient supply function of potassium.
Features of Water Soluble Potassium Humate Granule:
1. High water solubility: Solid granules of Water Soluble Potassium Humate Granule are easily soluble in water, with a solubility ≥90%, suitable for various application methods such as fertigation, drip irrigation, and foliar spraying.
2. High potassium content: Water Soluble Potassium Humate Granule typically contains ≥10% potassium oxide (K₂O), serving as a potassium supplement for crops.
3. Rich in humic acid: Total humic acid content ≥60% (dry basis), with some products containing 2%~5% fulvic acid, resulting in even stronger activity.
4. Alkaline pH value: The pH value of Water Soluble Potassium Humate Granule is generally 8–10, helping to adjust acidic soils.
5. Multifunctional Compound:
– Improves soil structure and enhances water and fertilizer retention capacity;
– Activates fixed phosphorus and potassium in the soil, reducing nutrient loss;
– Chelates micronutrients (such as iron, zinc, and manganese), increasing their availability;
– Stimulates root development, enhancing drought, cold, and disease resistance.
6. Wide Range of Applications: Water Soluble Potassium Humate Granule is suitable for vegetables, fruit trees, field crops, cash crops, and medicinal herbs.
Uses of Water Soluble Potassium Humate Granule:
1. Soil Improvement
– Increases soil organic matter and improves the structure of compacted and saline-alkali land;
– Increases cation exchange capacity (CEC), enhancing soil buffering capacity.
2. Use as Potassium Fertilizer
– Water Soluble Potassium Humate Granule supplements crops with the potassium they need, especially suitable for chlorine-sensitive crops (such as tobacco, grapes, and potatoes).
3. Improve Fertilizer Utilization
– Water Soluble Potassium Humate Granule, when combined with nitrogen, phosphorus, potassium, and micronutrients, can reduce fertilizer usage by 20%–30% while simultaneously improving nutrient absorption efficiency.
4. Enhance Crop Stress Resistance
– Reduces stomatal opening, decreases water transpiration, and enhances drought resistance;
– Thickens cell walls, improving cold resistance, disease resistance, and lodging resistance.
5. Improve Agricultural Product Quality
– Promotes flower bud differentiation and increases fruit set rate;
– Increases fruit sugar content, color, and commercial value.
6. Flexible application methods:
– Base fertilizer/topdressing: 10–30 kg/mu, applied by broadcasting, hole application, or furrow application;
– Fertigation/drip irrigation: Dilute 300–500 times, 10–20 kg/mu (or adjust according to crop type, such as 3 kg/mu for leafy vegetables, 10 kg/mu for fruit trees);
– Foliar spray: Dilute 500–1000 times, mainly used during flowering and fruit expansion stages.
