Leonardite occurs in deep layers of clay, which prevent other minerals and impurities from leeching into the Leonardite, resulting in a product that is purer. Leonardite adds organic matter to marginal soils improving texture, moisture-holding capacity, and pH stability. As a fertilizer enhancement, Leonardite improves a crop’s ability to absorb nutrients, resulting in faster growth, healthier and higher yields. Leonardite Products are environmentally stable and will not cause harmful effects to soil or groundwater.
