Unlock Soil Potential with OMRI Listed Soluble Humic Acid

Ferti-Organic Soluble Humic Acid is a premium potassium humate (0-0-7) derived from leonardite — one of nature’s richest sources of humic substances. With a minimum 75% humic content (including fulvic acids) and less than 1% insoluble matter, this dark black powder dissolves rapidly and gets to work immediately, improving soil structure, nutrient availability, and biological activity from the first application.

OMRI Listed for certified organic production. Trusted by professional growers in greenhouse, field crop, and hydroponic operations.

Key Benefits

• Breaks up compacted and clay soils: Anti-compaction agents improve water penetration and root zone access.
• Improves sandy soils: Adds essential organic matter to boost water retention and prevent nutrient leaching.
• Natural chelator: Bonds with calcium and frees up other nutrients, making them more plant-available.
• Stimulates microbial activity: High biological activity increases beneficial soil microorganism populations.
• Enhances nutrient uptake: Penetrates cell membranes to improve absorption of macro and micronutrients.
• Increases chlorophyll synthesis: Supports greener, healthier plant tissue and improved photosynthesis.
• Resistant to high-ion water: Performs reliably even in challenging water quality conditions.

Typical Applications

• Fertigation and drip irrigation programs
• Foliar spray for rapid soil and plant response
• Soil drench for compaction relief and structure improvement
• Organic hydroponic and soilless systems
• Blending into custom organic nutrient programs

Guaranteed Analysis

• Humic Content: >60%
