Humic Fulvic Acid Powder 70/10 Water Soluble Biostimulant for High Value Horticulture

A single molecule cannot do both jobs well. Humic acid is a large, high molecular weight structure that works in the soil, building aggregates and holding cations. Fulvic acid is small, oxygen rich and mobile, and it moves into the leaf and through the phloem in hours. This 70/10 powder delivers both in one bag, which is the combination that vegetable and fruit exporters in the Philippines and Vietnam keep asking for when they run a single drench and foliar programme.

The product is extracted in two stages from the same leonardite feedstock, then recombined and spray dried, so the ratio is controlled rather than approximated by blending two powders. Solubility is above 99 percent, which matters on high value crops because a residue in the spray tank blocks nozzles and burns leaf margins in the heat. In practice the fulvic fraction carries micronutrients into the leaf faster, while the humic fraction keeps working in the root zone for weeks.

• Dual fraction: 70% humic for soil structure plus 10% fulvic for rapid leaf and phloem mobility in one product.
• Controlled ratio: Two stage extraction from the same feedstock, not a blend of two purchased powders.
• High solubility: Over 99% soluble, leaving no tank residue and no nozzle blockage in high temperature spraying.
• Visible leaf response: Fulvic fraction drives nutrient translocation, with leaf colour change typically seen within seven days.
• Micronutrient carrier: Chelates iron, zinc and manganese, improving uptake on calcareous and high pH soils.
• Retail packaging: Foil lined pouches and moisture barrier bags suited to humid tropical storage and repacking.

Drench and drip: 3 to 6 kg per hectare every 10 to 14 days during vegetative and flowering stages. Foliar: 25 to 40 g per 100 litres, three applications at 10 day intervals around flowering and fruit set. For leafy vegetables, apply from the fourth leaf stage; for fruit crops, at flowering and again at fruit enlargement. On tissue culture banana, strawberry and cut flower production, the fulvic fraction is usually the reason growers choose this grade over straight humic acid, because leaf response is visible inside a week.

High value horticulture buyers in the Philippines, Vietnam and Thailand normally take 25 kg bags and repack into 500 g and 1 kg foil pouches for retail and e-commerce, so we supply moisture barrier liners to protect the powder in humid storage. A 20ft container loads 22 tons in 25 kg bags. We can supply a micronutrient compatibility chart for the buyer's local NPK and calcium products, which reduces the number of after sales technical questions a distributor has to answer.

Packing is 25 kg PP woven bag with foil barrier liner, 10 kg carton, or 500 g and 1 kg retail pouches to artwork. Each batch is tested for humic acid, fulvic acid, solubility, moisture and pH, and a retained sample is held for 24 months. Production is under ISO 9001 with third party heavy metal testing every six months.
