Sodium Humate Granules Granular Root Booster Lowland Rice Paddy Fields 60% Humic Acid

Lowland rice is grown in a soil that spends most of the season under water, and that changes what a humate product has to do. In a flooded paddy the granule must disperse into the reduced soil layer where new roots form, without floating to the surface and washing out with the overflow. This grade is screened to 0.5-1.5 mm and wetted fast enough to sink and dissolve within hours of the field being flooded.

Vietnamese and Thai growers in the Mekong and Chao Phraya deltas use it in two places: as a nursery treatment before transplanting, and as a base application worked into the puddled soil. Both are about root establishment. A rice plant that establishes three or four more crown roots per hill in the first three weeks tillers earlier, and that difference carries into panicle number more reliably than a late-season rescue application.

The granules are also used at seedling soaking. A 0.05-0.5% solution for 12-24 hours before sowing improves water uptake in the seed, and in our experience the effect is more consistent when the solution is made with clean water and used the same day rather than stored in an open tank.

• Paddy-tuned granule: 0.5-1.5 mm cut sinks and disperses into the reduced layer instead of floating on the floodwater.
• Root establishment focus: supports crown root initiation in the first three weeks after transplanting, when tiller number is set.
• Seed soaking grade: dissolves cleanly at 0.05-0.5% for seed treatment without leaving grit on the seed coat.
• Ammonium retention: the humate fraction holds ammonium against loss in flooded, low-oxygen soils where nitrification is slow.
• Works with urea and NPK: can be blended into the basal application or applied separately without harming the blend.
• Delta logistics experience: we ship regularly to Ho Chi Minh City and Laem Chabang with export documentation prepared for agricultural inputs.

Nursery and seedbed: mix 1-2 kg of granules per 100 square metres into the bed soil about a week before sowing, or soak seed in a 0.05-0.2% solution for 12 hours and dry it in shade before broadcasting. Basal application: 300-500 kg per hectare broadcast onto the puddled soil and incorporated before transplanting, or applied to the furrow and closed with mud.

Top dressing: 150-300 kg per hectare at tillering, applied when the field has a shallow water layer of 3-5 cm so the granules disperse. Foliar use at 0.05-0.1% is possible at panicle initiation but the soil route is more economical for paddy. On acid sulphate soils in the delta, do not apply more than 500 kg per hectare in one season without checking the soil sodium level, and never apply on the same day as a lime treatment.

Packing is 25 kg PP woven bags with PE liner, 40 bags per pallet, or 1,000 kg jumbo bags for cooperative and dealer orders. Bags can carry application instructions in English and Vietnamese. A 20GP loads 27 tonnes floor loaded or 25 tonnes on pallets.

Every lot ships with COA, MSDS and a certificate of origin for preferential tariff treatment where applicable. We hold a retained sample for twelve months and can supply a small trial quantity of 500 kg to 1 tonne so a cooperative can run a field comparison before committing to a full container. Factory audits and third-party inspection are welcome.
