Benefits

  1. Potassium Fulvate dissolves instantly and completely in water, forming a crystal-clear solution that never clogs nozzles or drip lines.
  2. It delivers extremely high fulvic acid content directly into plant cells within hours, providing the fastest biostimulant response available.
  3. It supplies readily available potassium (≥ 12 % K₂O) together with powerful chelating fulvic acid for immediate plant use.
  4. It dramatically boosts nutrient uptake efficiency of N, P, K, Ca, Mg and all micronutrients by 100 – 300 %.
  5. It rapidly increases root mass, fine root hairs, and overall root surface area by 40 – 80 %.
  6. It strongly enhances photosynthesis, chlorophyll synthesis, and carbohydrate accumulation in fruits and grains.
  7. It provides outstanding protection against drought, salinity, heat, cold, and disease stress.
  8. It corrects micronutrient deficiencies (especially Fe, Zn, Mn) with visible results within 2–4 days.
  9. It improves fruit size, color, sugar content, flavor, and significantly extends post-harvest shelf life.

Usage

  1. Foliar spraying (most effective method)
  2. Fertigation & drip irrigation systems
  3. Seed treatment & root dipping
  4. Hydroponics, NFT, and substrate culture
  5. Soil drench for orchards and field crops
  6. Tank-mix with liquid fertilizers, pesticides, and fungicides
  7. Biostimulant programs for high-value crops

Typical Application Rate

  • Foliar: 150 – 400 g/ha (0.01 – 0.05 % solution)
  • Fertigation: 2 – 5 kg/ha per cycle
  • Seed treatment: 300 – 600 g per 100 kg seed

Packaging

  1. 25 kg kraft paper bag with double PE + aluminum liner
  2. 20 kg kraft bag (export standard)
  3. 1 kg / 5 kg / 10 kg high-barrier aluminum foil bag
  4. 500 – 1000 kg big bag (FIBC)
