Huma OM 1–3mm Humic & Fulvic Acid Granules | OMRI Listed

The Organic Solution for Stimulating Soil & Crops

Huma OM 1–3mm is a natural humic and fulvic acid product processed from naturally occurring, oxidized humic substances. With a 70% humic/fulvic acid concentration, it delivers a potent, concentrated source of organic matter and is a supplemental source of trace elements driving measurable improvements in soil biology, nutrient availability, and crop performance.

OMRI Listed®: Certified for use in organic production, giving growers confidence that this input meets rigorous organic standards.

Benefits of Use

• Even Coverage & Distribution: Uniform 1–3mm granular size promotes consistent spread of humic/fulvic acid for sustainable carbon benefit.
• Long-Term Soil Organic Matter Building: Continuously builds soil carbon and organic matter with each application.
• Increased Water Penetration: Improves soil porosity and water infiltration for better moisture distribution.
• Increased Flocculation of Clays: Aggregates clay particles to improve soil structure, aeration, and drainage.
• Promotes Fertilizer Conversion: Helps convert applied fertilizer into plant-available food, improving input efficiency.
• Increases Soil Nutrient Mineralization: Accelerates the release of bound nutrients into plant-available forms.
• Sustainable Soil Microbial Activation: Feeds and activates beneficial soil microorganisms for lasting fertility gains.
• Improves Root Development: Promotes stronger root mass and growth for better nutrient and water uptake.
• Increases Crop Quality & Yield: Supports higher-quality harvests and improved overall productivity.

Product Features

• Uniform 1–3mm Granule: Ground and screened to a consistent crumble with less than 3% dust, ideal for blending with other dry inputs that are not hygroscopic.
• Broad Soil & Crop Compatibility: Can be applied to all soils and all crops.
• No Incorporation Required: Effective when surface-applied; incorporation is not necessary.
• Supplemental Trace Elements: Provides a natural supplemental source of trace elements alongside humic and fulvic acids.
