Natural Leonardite Humic Acid Granule Soil Conditioner For Indonesia Cocoa Maize Farms

Cocoa and maize anchor the farm economy of Sulawesi and Java, but continuous cropping has left many fields with declining organic carbon and tired, compacted soil. Natural Leonardite Humic Acid Granule is a slow release ground conditioner that rebuilds organic matter and restores biological activity where it matters most—in the root zone.

The granule is manufactured from natural leonardite without harsh chemical processing, so it retains the full spectrum of humic and fulvic substances. Spread and lightly incorporated, it gradually releases these materials season after season, reducing the need for frequent light top dressings.

Key Features
  • Natural Leonardite Origin: Produced from fossil leonardite rather than synthetic sources, retaining a broad natural humic spectrum.
  • High Humic Acid Load: A 65% minimum humic acid content gives a strong response from a modest spreading rate.
  • Slow Release Granule: The 2 to 4 mm granule breaks down gradually, feeding the soil over a full cropping cycle.
  • Improves Soil Biology: Provides carbon and humic substances that stimulate beneficial microbial populations.
  • Better Nutrient Retention: Increases exchange capacity so nitrogen, potassium and magnesium stay in the root zone.
  • Easy Mechanical Spreading: Uniform granules flow through broadcasters and can be banded along planting rows.

Applications

For cocoa and maize, broadcast 300 to 500 kg per hectare at planting and incorporate into the topsoil, or band 100 to 150 g per plant along the row. A second light application can be made before the reproductive stage if soil organic matter is very low.

The granule blends well with organic manure, biochar and compound NPK, and is widely used by Indonesian distributors building complete soil health programmes for plantation crops.

Packaging & Quality Assurance

Available in 25 kg PP bags with PE liner and 1,000 kg jumbo bags. Waterproof liners protect the granule during tropical storage.

A 20-foot container loads about 25 metric tons of 25 kg bags. Private label printing and full export documentation are available.
