Concentrated Humic Acid Powder 85% Organic Matter Rubber Tree Soil Conditioner
Huayuan concentrated humic acid powder contains a guaranteed minimum of 85% organic matter on a dry basis, offering plantation buyers a highly concentrated soil conditioner that delivers results at low application rates. Sourced from premium Ningxia weathered coal, the powder is ideal for rubber tree estates in Thailand and neighboring tropical markets, where compacted, acidified and nutrient-depleted soils limit root development and latex production.
Key Features
- Concentrated Formula: Minimum 85% organic matter means smaller application rates and lower freight cost per hectare compared with low-grade amendments.
- Rubber Tree Optimized: Improves the heavy, compacted lateritic soils typical of rubber estates, supporting healthier root systems and steadier latex yield.
- Soil Structure Builder: Binds soil particles into stable aggregates, increasing porosity, water infiltration and root penetration.
- Slow Carbon Release: The natural powder form feeds soil microbes gradually, sustaining fertility through the entire tapping cycle.
- Reduces Fertilizer Leaching: Higher CEC keeps applied NPK nutrients in the root zone, lowering input costs on sloping plantation land.
