Slow-Release Humic Acid Granule with 85% Organic Matter and 2-4mm Particle Size for Soil Conditioning

Huayuan slow-release humic acid granules are manufactured from carefully selected weathered coal extracted from our own mines in Xinjiang and Shanxi, China. The raw coal is directly crushed, disc-granulated, dried and cooled without any chemical activation, so the active functional groups remain fully intact. This unactivated form delivers organic matter into the soil gradually, providing a steady, long-lasting supply of nutrients that is ideal for large-scale palm oil plantations across Indonesia and the wider Southeast Asian region.

Apply as a base fertiliser before planting or during replanting of oil palm. For mature plantations, broadcast 300-600 kg per hectare and incorporate into the topsoil along the frond stacking rows. For nursery and immature palms, mix with compound NPK fertiliser to improve nutrient uptake and reduce chemical input. The granules may be applied by tractor spreader, drone, or manual broadcasting, and are fully compatible with standard plantation maintenance schedules.

Supplied in 25 kg woven polypropylene bags, 1 ton jumbo bags, or customer-designated packaging. Every production batch is ISO 9001 certified and shipped with a certificate of analysis. We maintain a supply capacity of 50 tons per day and accept flexible L/C or T/T payment terms to support B2B importers, distributors and plantation buyers across Southeast Asia and the Middle East.
