Leonardite is a geological deposit of organic material, containing concentrated humic acids in the form of oxidizing lignites (humates). Mined from naturally occurring sources, TEP humates are an economical method of adding humic acid to the soil.
These humates improve the soils ability to stabilize pH and the capacity to hold moisture. Because some soils typical of Western U.S. may be deficient, TEP Leonardite as an amendment will improve a crops ability to take in nutrients, boost yields, expedite growth, and an overall healthier plant.
Applied any time of the year. (500 lbs./acre, every three years)
