FAQs

The Organic Solution for Stimulating Soil & Crops 

Huma’s OM 6 mm(-) is a natural humic and fulvic acid product processed from naturally occurring, oxidized lignite. It provides a concentrated source of humic and fulvic acids and is a supplemental source of trace elements. Humic and fulvic acids add organic matter to soils—which stimulates soil microbial life and soil fertility, enhances plant nutrient availability and uptake, improves root development and root mass and growth, and increases crop quality and yield. 

OMRI-Listed® OM 6 mm(-) is ground and screened to a particle size of 6 mm (¼ inches) or smaller (contains less than 40% dust) and is ideal for spreading on and incorporating into soil. This product is a 70% humic/fulvic acid that can be applied to all soils—broadcast in fall, post-harvest, or early spring—either pre-plant or with seed. Incorporation is not required. It can be applied in bands, either with seed, fertilizer, or after planting.

50 lb. Paper Kraft Bags – Our fifty-pound bags are “blow-in” type bags with 2 paper layers and an inner layer of impermeable plastic. Air holes in the bags allow the product to be blown in through an opening in the top of the bag. This opening is self-closing when the bag is filled to capacity. Fifty-pound bags are stacked on 40×48″ pallets for shipping, with 45 bags to the pallet (2,250 pounds of product per pallet. The pallets themselves weigh 50 pounds). Shrink wrapping of palleted bags is available upon request. The bags are a plain brown paper with no printing. Pre-printed customer bags can be filled upon request.

1Ton Mini Tote Bags – The most popular method for shipping our products is in mini-bulk bags, each of which holds approximately 1 ton of product. These bags are made of a synthetic material and are resistant to moisture. The bags are “duffel top”, meaning they can be tied closed at the top. A spout on the bottom of the mini-bulk bags is tied closed for filling and can be opened to allow dumping of the product into a hopper or mixer. Straps at the four top corners of the bags allow easy handling with a forklift. We can ship mini-bulk bags on pallets (36×26″) upon request.

Bulk – Granular humate products can be shipped in larger bulk storage containers such as grain trucks (hoppers), belt trailers, etc. Please inquire if you are interested in bulk shipments.

75-150 lbs. per acre, broadcast in fall, post-harvest or early spring, either pre-plant or with seed. Incorporation not required. Banding: either with seed or after planting, reduce application rates proportionally. Can be applied to all crops.
