Factory Direct Supply FA-3 Biochemical potassium fulvate Powder for Global Fertilizer Manufacturers

FA-3 Biochemical potassium fulvate Powder adopts modern biotechnology. Using sugarcane, beet and molasses as raw materials, it undergoes deep biological fermentation to produce high-activity biochemical humic acid substances with properties similar to coal-based humic acid.

This product features full water solubility, strong acid & alkali resistance, and tolerance to divalent metal ions. It can be compounded with various macro and trace elements without flocculation or precipitation.

It can be applied directly to farmland, and also serves as the core raw material or additive for foliar fertilizers, water-soluble flush fertilizers, organic fertilizers, pesticide compound fertilizers, trace element fertilizers, aquaculture fertilizers, liquid mulch films, and humic acid water-retaining agents. Additionally, it works as the slow-release coating stock solution for tower granulation of organic-inorganic compound fertilizers.

We take molasses as the carbon source for yeast fermentation. After yeast centrifugation, the yeast metabolites are concentrated via six-effect evaporation, then spray-dried into finished powder — Biochemical potassium fulvate Powder FA-3.

This product is made of 100% pure organic ingredients with zero inorganic chemical additives. Its color ranges from brown to tan powder. Slight color differences between batches or production lines are normal and will not affect the product’s intrinsic composition and efficacy.

It is rich in secondary & trace elements including sulfur, calcium, magnesium, zinc, iron, molybdenum and boron. It also contains abundant B vitamins, vitamin C, inositol, polysaccharides, bacterial protein, nucleic acid, surfactants and natural plant growth-promoting bioactive factors.

• Activate compacted soil, optimize crop physiological metabolism, boost root development and lush foliage for fruits, vegetables and field crops.
• Available for base application, flushing and topdressing. 20–30 kg per mu for flushing/topdressing can cut general fertilizer usage, advance crop maturity by around 10 days, and raise yield by over 20%. It extends picking & fresh-keeping period, prevents flower & fruit drop, raises fruit sugar content and improves fruit quality.

• Improve soil crumb structure, loosen hardened soil, strengthen water & fertilizer retention capacity, adjust soil pH, reduce heavy metal content and relieve salt damage to seeds and seedlings.
• Fix nitrogen, release phosphorus and activate potassium; delivers outstanding potassium synergistic effect, strengthens roots & seedlings, alleviates continuous cropping obstacles, enhances disease resistance and upgrades crop quality.
• Boost root adhesion and nutrient absorption efficiency; effectively relieve physiological diseases caused by trace element deficiency.

• Fertilize water body, prevent aquatic diseases and accelerate growth; eliminate toxic ammonia nitrogen and nitrite. When matched with biological water purifiers, it purifies water, alleviates eutrophication and builds balanced ecological aquaculture environment.
• Chelate with specific chemicals to form eco-friendly reagents, safely remove parasites and excess harmful algae without damaging aquatic ecosystem balance.
• Feed manufacturers can directly add it into aquatic feed to produce antibiotic-free green feed; farmers can also sprinkle the powder into ponds during breeding.

• Supplies calcium, amino acids especially lysine and bioactive protein for piglets and young poultry; significantly boosts milk yield of dairy cows and sows. It carries natural yeast aroma and molasses sweetness with strong feeding attraction for all livestock.
• Stimulate biological activity to prevent diseases and speed up growth: multiple active groups and unknown growth factors activate animal enzymes, boost metabolism and immunity, effectively treat intestinal diseases and white scour in livestock.
• Boost nutrient absorption and feed utilization: acidic functional groups chelate trace elements (Fe, Cu, Zn, Mn) into absorbable organic minerals. Its mild acidity adjusts gastrointestinal pH to improve nutrient conversion, cut fish meal and whey powder consumption and raise feed efficiency.

1. Wide universal compatibility: Used as main material or carrier for foliar fertilizer, trace element fertilizer, flushing fertilizer, root irrigation fertilizer, compound fertilizer, bio-bacterial fertilizer, hydroponic nutrient solution, seed coating agent, seed mixing agent, root dipping powder. It also improves soil, regulates pH and alleviates saline-alkali soil, and acts as pesticide carrier & synergist for pesticide-fertilizer integrated products.
2. Base fertilizer / hole application / flushing: 50 kg per mu
3. Foliar spraying & drip irrigation: 10 kg per mu
4. Powdered liquid mulch: Spread evenly on soil surface; forms film within 10 minutes and degrades into fertilizer naturally after seedling emergence, saving labor and mulch costs.
