Sodium Humate Granules 60% Humic Acid Coarse Grade for Saline-Alkali Land Reclamation

Sodium humate granules in this coarse grade are manufactured for one job: bringing salt-affected and alkali land back into production. The granules are screened to 1.5-2.5 mm, air dried rather than kiln dried, and carry a minimum 60% total humic acid on a dry basis. We ship them from our own weathered coal base in Ningxia, where the raw material is leached with sodium hydroxide, settled in two stages over 48 hours, then concentrated and turned on the drying floor until the moisture drops below 15%.

Buyers in Saudi Arabia, Pakistan and the Gulf often ask us why granule size matters for reclamation work. Fine powder blows away during field application and clogs the spreader at the hopper throat; 1.5-2.5 mm granules flow evenly at 8-15 kg per minute through a standard twin-disc spreader, which is what makes hectare-scale reclamation practical. The granules also dissolve progressively, so the humate reaches the root zone over two to three irrigation cycles instead of being flushed straight past it.

This product is supplied with a batch certificate of analysis, a Chinese customs commodity inspection record where required, and a shipping document set that matches the HS code 38249999. If your soil report shows an exchangeable sodium percentage above 15%, our technical team will help you set a leaching rate before you commit to a container.

• Coarse 1.5-2.5 mm granule: screened for uniform spreader flow, low dust in the warehouse, and less product loss on windy ground.
• 60% minimum humic acid: total humic acid ≥60% and total organic matter ≥80% on a dry basis, verified batch by batch in our own laboratory.
• Air-dried process: no high-temperature treatment, so the active humic fraction and microbial compatibility stay intact.
• Alkali buffer effect: the sodium humate fraction neutralises free carbonate and bicarbonate, and the calcium bridging action rebuilds aggregate structure in sodic soils.
• Heavy metal passivation: humic and fulvic fractions adsorb free aluminium, manganese and cadmium ions, reducing their availability to young roots.
• Export packaging discipline: 25 kg woven bags on 1.25 tonne pallets or 1 tonne jumbo bags, with liner protection against monsoon humidity.

For acidic or degraded upland soil, apply 1,500-3,000 kg per hectare and incorporate to 15 cm about ten days before sowing, so the granules have time to react with the topsoil before the seedbed is prepared. For light to moderate saline-alkali land, 750-2,250 kg per hectare combined with gypsum works better than either material alone, and should be followed by a leaching irrigation of 600-900 m3 per hectare to push sodium ions below the root zone.

On established plantations, a band application of 400-600 g per palm or per mature tree at the drip line, twice per season, keeps the soil exchange complex in better condition without disturbing the feeder roots. For row crops, 150-600 kg per hectare as a top dressing works well when it is watered in immediately; do not leave granules on the surface under strong sun for more than a day.

Standard packing is 25 kg PP woven bags with an inner PE liner, 40 bags per 1,000 kg pallet, or 1,000 kg jumbo bags with discharge spout. Private label printing is available from 500 bags per size, and we can print your own NPK analysis block, lot number and market-specific warning statements. Container loading is 25 tonnes per 20GP with pallets or 27 tonnes floor loaded.

Every shipment leaves with a COA for the actual production lot, an MSDS in English, and a packing list that reconciles bags, pallets and container seal number. Our ISO 9001:2015 system covers incoming weathered coal, reaction control, screening and final release testing, and third-party inspection through SGS or BV can be arranged at your cost before loading. If a lot fails your incoming specification, we replace it against the retained sample, which we keep for twelve months.
