High-Organic-Matter Humic Acid Soil Amendment Granules 25kg Bag Rubber Tree Crops
Huayuan high-organic-matter humic acid granules contain a guaranteed minimum of 85% organic matter on a dry basis, making them one of the most concentrated organic soil amendments available for rubber tree plantations and tropical cash crops in Thailand and Southeast Asia. Sourced from premium Xinjiang and Shanxi weathered coal, the product rebuilds soil organic carbon and restores fertility to degraded lateritic and sandy plantation soils.
Key Features
Min 85% Organic Matter: an exceptionally high organic content rebuilds soil structure, improves aeration and provides a stable carbon reserve for long-term fertility.
Rubber Tree Optimised: improves the heavy, compacted and acidified soils typical of rubber estates, supporting healthier root systems and more consistent latex yield.
Slow-Release Carbon Source: the unactivated form releases organic matter gradually, feeding soil microbes and sustaining fertility across the entire tapping cycle.
Improves Soil Structure: humic acid binds soil particles into stable aggregates, increasing porosity, water infiltration and root penetration.
Reduces Fertiliser Leaching: higher CEC retains applied NPK nutrients in the root zone, cutting input costs and environmental loss on sloping plantation land.

Applications
Apply 750-1500 kg per hectare for mature rubber trees using furrow or hole application along the canopy drip line, then cover with soil. For young rubber and nursery stock, mix with organic fertiliser at 450-900 kg per hectare. Suitable for broadcast, banding or mechanical incorporation into the planting rows.
Packaging & Quality Assurance
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.
