Zinc Fortified Humic Acid Granules 60% Plus 2% Zn for Saline Sandy Soils

Zinc deficiency is easy to miss until yield is already lost. On calcareous sand in Saudi Arabia and the coastal sandy soils of Ilocos and Binh Thuan, pH above 7.5 locks zinc into forms the plant cannot take, and the first visible sign is interveinal chlorosis on the younger leaves, long after the root system has already thinned. This granule puts zinc sulphate into a humate matrix so the zinc is released slowly and stays plant available instead of being fixed by carbonate.

Two percent zinc does not sound like much, but at 100 kg per hectare it delivers two kilos of Zn, which covers three to four seasons of normal crop removal on cereals and vegetables. The humic carrier also improves the distribution: zinc sulphate alone is highly soluble and moves out of sandy soil with the first irrigation, while the granule releases it across the root zone for eight to twelve weeks.

• Zinc in plant form: Granulated zinc sulphate in a humate matrix releases Zn slowly instead of being fixed by free carbonate.
• Corrects hidden hunger: Addresses interveinal chlorosis and root thinning on calcareous and sandy soils above pH 7.5.
• Seasons of cover: 2% Zn at 100 kg per hectare covers three to four seasons of normal crop removal.
• Less leaching: Slow release keeps zinc in the root zone instead of washing out with the first irrigation on sand.
• Assayed every lot: ICP zinc assay and heavy metal report supplied per batch for Gulf import requirements.
• Advice in writing: We adjust the rate against the buyer's soil analysis before the order is confirmed.

Broadcast and incorporate 50 to 100 kg per hectare for cereals, vegetables and fodder crops, 100 to 150 kg per hectare for date palm, citrus and mango in the planting basin. Apply before planting or at the start of the rainy season, and keep the granule within the root zone rather than on the surface. Do not mix with high phosphorus compound fertiliser in the same band, because zinc and phosphate compete and the zinc becomes less available.

Saudi and UAE importers usually require a heavy metal report and a zinc assay from an accredited laboratory, and we supply both per lot. For the Philippines and Vietnam, distributors repack into 5 kg bags for vegetable growers. A 20ft container carries 25 tons. If the buyer has soil analysis showing the actual Zn level, we will adjust the recommended rate in writing before the order is confirmed.

Packing is 25 kg PP woven bag with PE liner, 5 kg retail bag, or 1 ton jumbo bag. Zinc content is assayed by ICP on every batch, and heavy metals are tested every six months. Retained samples are kept for 24 months under ISO 9001 control, and the lot number on the bag links back to the assay report.
