Down to Earth Granular Humic Acids | 50lb - OMRI Listed

OMRI Listed Granular Humic Acids from Oxidized Lignite for Nutrient Uptake (50lb)

Down to Earth Granular Humic Acids is an OMRI Listed, highly concentrated source of humic acids derived from the ancient remains of decomposed organic plant materials — naturally occurring, unaltered oxidized lignite. Containing 70% total humic and fulvic acids, it is crushed, screened, and graded to a uniform particle size of 1–3 mm. Humic acids enhance nutrient uptake and stimulate soil microbial life, making it suited for fields, turf, and vegetable gardens.

The 50lb size is suited for larger fields, market gardens, and turf managers who apply granular humic acids across broad areas as a regular soil biology and fertility amendment.

Key Features & Benefits

• 70% Total Humic and Fulvic Acids — Highly concentrated source from naturally occurring, unaltered oxidized lignite.
• OMRI Listed — Approved for certified organic production.
• Enhances Nutrient Uptake — Humic acids improve the availability and uptake of nutrients by plant roots.
• Stimulates Soil Microbial Life — Supports beneficial soil microbial populations through humic acid activity.
• Uniform 1-3 mm Granules — Crushed, screened, and graded to 1-3 mm for consistent particle size and application.

Who Should Use Down to Earth Granular Humic Acids

Granular Humic Acids suits organic farmers, market gardeners, turf managers, and home gardeners who want to improve soil biology, nutrient uptake efficiency, and overall soil health. Particularly useful for those who want a concentrated humic acid source for fields, vegetable gardens, and turfgrass areas.

Humic Acids and Soil Biology

Humic acids are complex organic compounds that form during the long-term decomposition of organic plant materials. In soil, humic acids interact with minerals and nutrients to improve nutrient availability and uptake by plant roots. They also support beneficial soil microorganism populations that contribute to nutrient cycling and soil structure. Granular Humic Acids is derived from oxidized lignite — an ancient organic material containing a concentrated reservoir of humic and fulvic acids in a stable, granular form.

Frequently Asked Questions

What are humic acids and why are they beneficial?

Humic acids are complex organic compounds formed from decomposed plant materials. In soil, they improve nutrient availability, enhance root uptake of nutrients, and support beneficial soil microorganism populations.

Is Down to Earth Granular Humic Acids OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

What is oxidized lignite?

Oxidized lignite is a naturally occurring ancient organic material derived from the long-term decomposition and geological transformation of plant materials. It is a concentrated source of humic and fulvic acids in a stable, unaltered form.

What is the particle size of Granular Humic Acids?

It is crushed, screened, and graded to a uniform particle size of 1–3 mm, providing consistent granules suited for broadcast applications on fields, turf, and gardens.

Can Granular Humic Acids be used on turf?

Yes. It is suited for fields, turf, and vegetable gardens. For turfgrass, it can be applied to improve soil biology and nutrient uptake. Follow current label directions for application rates by use type.
