2-4mm Slow Release Humic Acid Granule with 65% Humic Acid for Greenhouse Soil Amendment

Protected vegetable production is expanding rapidly across Saudi Arabia, where growers rely on soil beds and substrate systems under high heat and heavy irrigation. This granular amendment improves the root environment in intensive greenhouse systems and helps crops use water and nutrients more efficiently.

The uniform 2 to 4 mm granule is designed for measured application in beds, pots and troughs, releasing humic substances gradually so the soil keeps working between irrigation cycles. It suits tomato, cucumber, pepper and leafy crops grown for domestic markets and export.

• Greenhouse Ready Granule: Uniform 2 to 4 mm size is easy to meter into beds, pots and troughs in protected systems.
• Slow Release Action: Humic substances are released gradually, keeping soil condition stable between irrigations.
• Improves Water Use: Better aggregation and water holding help crops in high temperature greenhouse conditions.
• High Humic Content: A 65% minimum humic acid content supports strong root and soil biological activity.
• Low Dust Granule: Screened granules produce minimal dust, important in enclosed greenhouse environments.
• Export Documentation: ISO 9001:2015 production supporting COA, MSDS and full export paperwork.

For greenhouse tomato, cucumber and pepper: Incorporate 200 to 300 kg per hectare into the beds before planting, or sidress 10 to 20 g per plant every four weeks.

For leafy crops: Apply 150 to 250 kg per hectare at bed preparation.

The granule mixes with compost, organic manure and soluble NPK programmes, letting Saudi growers build a complete soil and fertigation plan for high value protected crops.

Packaging: Supplied in 25 kg PP bags with PE liner and 1,000 kg jumbo bags, with moisture resistant packaging suited to desert storage.

Documentation: Each shipment includes a certificate of analysis, material safety data sheet and application guide, with technical support for greenhouse nutrition planning.

Shipping: A 20-foot container loads about 25 metric tons, supporting efficient landed cost for Saudi importers and distributors.
