Concentrated Liquid Humic Acid 12% Foliar Spray Root Drench Biostimulant for Tropical Crops

Not every farm has a mixing tank or the labour to dissolve powder. This suspension concentrate puts 12 percent humic acid in a stable liquid form that pours straight into a sprayer or a drip line, and stays in suspension for 24 months without hard sediment in the drum. The carrier is potassium based, so the product also contributes a small amount of soluble potash, which is useful in foliar programs where the grower does not want to add another salt.

We recommend it for three situations that come up constantly in Southeast Asian production: recovery after flooding or waterlogging, transplant shock on vegetables and tobacco, and heat stress during the dry season on fruit trees. Foliar uptake of the low molecular fraction is fast, and growers typically report visible leaf colour change within five to seven days, followed by new flush. For root drench it works through the soil solution rather than through the leaf.

• Ready to use: Pours directly into sprayer or fertigation tank, no dissolving step and no blocked filters.
• Stable suspension: No hard sediment over 24 months, so the last litre in the drum matches the first.
• Fast foliar response: Low molecular humic fraction is taken up through the leaf, with colour change usually visible in five to seven days.
• Stress recovery: Widely used after flooding, transplanting and heat stress on vegetables, tobacco and fruit trees.
• Potassium carrier: Contributes soluble potash, reducing the number of salts added to a foliar programme.
• Freight efficient: Concentrated 12% formulation keeps shipping cost per hectare low compared with dilute liquids.

Foliar: dilute 1:500, i.e. 200 ml per 100 litres of water, and spray to run off at early morning or after 4 pm. Root drench: 1:200, or 5 to 10 litres per hectare through drip, every 2 to 3 weeks. Seedling dip: 1:300 for 30 seconds before transplanting. Do not mix with strongly acidic products, and never tank mix with copper based fungicides at high concentration because the humate will flocculate the copper. In hard water areas above 400 ppm calcium, dilute in two stages and keep the final concentration at or below 1:500.

Liquid volume is expensive to ship, so most importers order 200 litre drums or 1000 litre IBC totes and repack locally. A 20ft container takes 80 drums of 200 litres, about 18 tons net. For Vietnam, Thailand and the Philippines we quote CIF to Ho Chi Minh, Laem Chabang and Manila, and we can supply the repacking pump and hose kit for buyers running a local filling line. Cold chain is not needed; the product is stable from 5 to 40 C.

Available in 1 litre and 5 litre bottles, 20 litre jerry can, 200 litre drum and 1000 litre IBC, all with tamper evident seals and a batch label. Viscosity, pH, density and humic acid content are tested on every batch, and a 500 ml retention sample is kept for 24 months. The plant operates under ISO 9001 and dangerous goods classification documents are supplied for sea freight.
