Slow Release Humic Acid Granule Soil Conditioner with 65% Humic Acid Content for Improved Soil Structure

Oil palm estates across Sumatra and Kalimantan work soils that lose organic carbon quickly under heavy rainfall and continuous harvesting. Slow Release Humic Acid Granule Soil Conditioner is a 2 to 4 mm granule made from weathered leonardite, designed to release humic substances gradually through the root zone instead of washing away after the first monsoon.

The material comes from a specialist humic acid manufacturer with more than fifteen years of continuous production experience and an in-house soil science team. Every formulation is reviewed with plantation agronomists and trialled on oil palm, rice and cocoa before it is offered to the market, so buyers receive a product supported by documented field experience rather than marketing claims.

Supplied in 25 kg PP woven bags with PE liner and 1,000 kg jumbo bags. Private label and bilingual printing are available, and every bag carries a traceable batch number.

Quality is documented rather than claimed. Each shipment includes a certificate of analysis, a material safety data sheet and an application guide, and our technical team provides agronomic support for distributors and estates.

A 20-foot container loads about 25 metric tons of 25 kg bags, which supports a competitive landed cost for Indonesian importers and distributors.
