Huma OM 1–3mm Humic & Fulvic Acid Granules | Bulk | 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.
