Main Functions
- Super Potassium Humate dissolves instantly and completely, forming a perfectly clear dark solution that never blocks nozzles or drip lines.
- It provides the highest water-soluble humic acid (≥ 98 %) combined with ≥ 15 % natural fulvic acid for maximum biostimulant activity.
- It supplies high-analysis organic potassium (≥ 12 % K₂O) in immediately plant-available form without salinity risk.
- It dramatically increases nutrient absorption of N, P, K, Ca, Mg and all trace elements by 100 – 300 %.
- It rapidly stimulates root and shoot growth, resulting in 30 – 60 % larger root systems within weeks.
- It strongly boosts photosynthesis, chlorophyll content, and carbohydrate translocation to fruits and grains.
- It offers superior protection against drought, salinity, heat, cold, and disease pressure.
- It corrects micronutrient deficiencies within days and prevents blossom-end rot and bitter pit.
- It significantly improves fruit size, color, sugar content, flavor, and storage life of harvested produce.
Usage
- Foliar spraying (most popular & fastest response)
- Fertigation & drip irrigation
- Seed treatment & seedling root dipping
- Hydroponics & soilless cultivation
- Soil drench for orchards, vegetables, and field crops
- Tank-mix with liquid NPK, pesticides, and growth regulators
- High-end biostimulant programs worldwide
Typical Application Rate
- Foliar: 200 – 500 g/ha (0.02 – 0.05 % solution)
- Fertigation: 3 – 8 kg/ha per cycle
- Seed treatment: 400 – 800 g per 100 kg seed
