- Core Mechanisms
- Soil conditioning: Fulvic acid bonds soil particles via carboxyl & phenolic hydroxyl groups to form aggregates, boosting porosity by 15%-30% and water/nutrient retention; saline-alkali soil permeability rises 40%.
- Nutrient activation: Chelates fixed P & K to raise release efficiency by 50%; cuts nitrogen volatilization 30%-50% when mixed with chemical fertilizers (45% less ammonia loss for urea + potassium fulvate).
- Stress resistance: Stimulates crops to generate proline and SOD enzymes; leaf water retention +20% under drought, root vigor +35% under salt stress.
- Application Plans
Cash Crops
- Fruit trees: 5kg mineral potassium fulvate/mu fertigated at fruit swelling; apple sugar up 2-3 °Brix, fruit cracking down 50%.
- Vegetables: 800* foliar spray; cucumber VC +18%, nitrate -25%.
Field Crops- Rice: 10kg bio-fermented potassium fulvate/mu base fertilizer at tillering; effective tillers +15%, 1000-grain weight +5%.
- Wheat: Mixed with topdressing at jointing; 8-10 more grains per ear, Fusarium head blight rate -30%.
- Notes
- Avoid mixing with strong alkaline pesticides (Bordeaux mixture, lime sulfur). Keep a ≥7-day interval.
- Saline-alkali land limit: Max 500g mineral potassium fulvate per mu to stop extra salt release from over-complexation
- Water Quality Optimization: Adsorbs ammonia nitrogen and nitrite with 60%-70% binding rate; stabilizes water pH at 7.5-8.5 to lower fish ammonia poisoning risks.
- Algae Balance: Supplies carbon source with 10:1 C/N ratio, raises diatom proportion from 30% to 60% and restricts cyanobacteria below 10%.
- Sediment Improvement: Degrades hydrogen sulfide in pond mud with ≥50% removal rate, multiplies beneficial benthic bacillus by 3-5 times.
