Dark Humic Acid Powder 60% Soluble Organic Biostimulant for Turf Nursery Seedling Media

Turf managers and nursery growers buy humic acid for a different reason than row crop farmers: they need a product that will not stain paved surfaces badly, will not leave visible residue on leaf blades, and will mix evenly into a peat or peat based growing medium. This 60 percent powder is milled to 100 mesh and screened for solubility, so it disperses into a dark solution that can be injected through a golf course irrigation system without settling in the tank.

On turf, the effect buyers care about is root density in the top 50 mm and recovery after coring or heavy play. On seedlings, the effect is uniform emergence and a stronger stem before transplanting. We supply the grade to nursery media producers who mix it into the substrate at 3 to 5 percent by volume, and to turf contractors who spray it at 2 to 5 g per square metre every three to four weeks during the growing season.

• Clean dispersion: 100 mesh grind dissolves to a dark solution that passes irrigation filters without tank sediment.
• Turf root density: Improves root mass in the top 50 mm and speeds recovery after coring and heavy play.
• Uniform emergence: Used in seedling media at 3-5% by volume for even germination and stronger stems.
• Media compatible: Blends dry into peat peat and bark mixes without clumping or changing the mix structure.
• Low staining: Formulated for turf and ornamental use, with a lower staining tendency than crude leonardite slurry.
• Rate card included: Metric and imperial dosing charts supplied with each order for contractors and landscapers.

Turf: 2 to 5 g per square metre in 5 to 10 litres of water per 100 square metres, every 3 to 4 weeks, or 20 to 30 kg per hectare through fertigation. Sports turf renovation: 5 g per square metre after coring, watered in immediately. Nursery media: 3 to 5 percent by volume in peat, peat or bark mix, blended dry before filling. Seedling drench: 1:800 every 10 days after emergence. Ornamental pots and interior landscaping: 1 to 2 g per litre of substrate.

Our turf and nursery buyers in Thailand, the Philippines and Vietnam usually order 25 kg bags and repack into 1 kg and 2 kg pouches for garden centres. A 20ft container loads 24 tons in 25 kg bags. We supply a mixing rate card in both metric and imperial units, which saves the buyer explaining conversions to landscape contractors. For golf course distributors we can quote a 10 kg bag with a dosing chart printed on the back panel.

Packing is 25 kg PP woven bag with PE liner, 10 kg bag, or 1 kg and 2 kg retail pouches to artwork. Each batch is tested for humic acid, solubility, moisture, pH and mesh size, with a retained sample kept for 24 months. Production follows ISO 9001 procedures and shipments include COA and MSDS as standard.
