Product Overview

  • Long-Lasting Soil Amendment: Slowly releases humic acid via microbial degradation (3-6 months sustained effect), boosting soil CEC (≥200 meq/100g), promoting aggregate structure, and effectively ameliorating saline-alkaline/compacted soils.
  • Mechanization-Friendly: Uniform particle size enables seamless use with fertilizer spreaders/seeding machines, slashing labor costs by 60% for large-scale fields, orchards, and plantations.
  • Eco & Low Loss: Dust-free during application (protects operator health/equipment), resistant to moisture caking, and transportation loss ≤1% (vs. 5-8% for powder), reducing logistics/packaging costs.
