Granular Humic Acid 3mm Organic Soil Amendment for Coconut Banana Pepper Plantations

Perennial plantations are applied by hand, plant by plant, and a 3 mm granule is the size that a worker can dose accurately with a scoop without the material running off the ring. This grade is made for coconut, banana, black pepper, areca and coffee grown on acid upland soils in the Philippines, Vietnam and southern Thailand, where the topsoil is thin and organic matter is below two percent after years of continuous cropping.

The agronomic case is simple. These crops are fed two or three times a year with compound fertiliser, and without exchange capacity a large share of the potassium and magnesium leaves the root zone with the first heavy rain. Humic granules hold those cations near the feeding roots, improve water holding in the ring, and support the fine root mass that black pepper in particular needs to survive a wet season without vine decline.

• Accurate hand dosing: Uniform 3 mm granules let workers dose by scoop without runoff from the plant ring.
• Perennial root support: Improves fine root mass and water holding in the ring, which matters for black pepper vine survival.
• Cation retention: Holds potassium and magnesium against heavy tropical rainfall leaching on acid upland soils.
• Low fines: Screened with under 5% fines and tested for hardness, so the product arrives as granules not dust.
• Crop specific guidance: Dosing tables for coconut, banana, pepper and coffee printed on the bag in local languages.
• Blend compatible: Can enter an organic NPK blend at up to 10% without affecting granule strength.

Coconut and areca: 100 to 150 g per palm per application, three times a year, broadcast in the basin at 1 to 1.5 m from the trunk. Banana: 80 to 120 g per mat, at planting and every three months. Black pepper: 100 to 150 g per vine per year, split into two rounds and placed in the ring under the canopy, not against the stem. Coffee and cocoa: 80 to 120 g per tree per round. Apply when soil is moist and cover lightly with mulch or soil to slow drying.

Plantation buyers usually order by the container and split the bags between estates, so we print the dosing table for each crop on the bag in English, Bahasa or Vietnamese. A 20ft container carries 25 tons in 25 kg bags. For buyers who also run a blending line, this grade can go into an organic NPK blend at up to 10 percent. Shipment to Manila, Ho Chi Minh, Bangkok and Port Klang takes 12 to 20 days from Tianjin.

Packing is 25 kg PP woven bag with PE liner, 1 ton jumbo bag, or 5 kg estate pack. Granules are screened to a 3 mm nominal size with less than 5 percent fines, and hardness is tested on each batch so the product survives a rough truck ride to the estate. Batch COA covers humic acid, moisture, pH, granule size and hardness. Production is under ISO 9001.
