Why OMRI Certified Organic?

By prioritizing the longterm health, longevity, and sustainability of the soil integral to their business and bottom line, organic farms have an inherently thoughtful and longterm approach. Prioritizing quality over quantity and committing to sustainable practices, organic producers understand that serving the earth first results in nutrientdense and healthy crops for consumption by humans and animals alike.

What Your Organic Soil Needs

Natural Minerals = Healthy Ecosystem

Organic producers are faced with daily challenges. Without replenishing the soil with natural minerals, soil structures are often impeded and unable to process and preserve water as it moves from the environment to the field to the plant. Common agripractices can often detract from sustainability and the destruction of the soil tilth. Organic producers understand leveraging the symbiotic relationship of mineral inputs, biology, and soil structure to promote soil fertility and health. Nutrient density, yield, and sustainability are complementary principles of organic producers and GLC Mineral products bolster each of those principles.

See the OMRI Certified Organic Difference

Organic producers understand that all farming begins with the soil. Replenishing the soil with natural carbonates and gypsum rejuvenates the complex soil ecosystem. Adding mineral soil nutrition spurs mineral release and transfer from the soil to the crop. When brought back into balance and sustained, the soil will naturally reduce its reliance of chemical inputs as its health increases.

for organic production. GLC Minerals recognizes OMRI as a national leader in organic certification.

As a national leader in organic certification, OMRI is routinely recognized for its independent evaluation
