Revitalize Your Soil

Long ago, before man walked the earth, a strange landscape of pre-historic plants and animals both lived and died under a primordial sun. Layer after layer, their decomposing remains re-united with the earth from which they came. These concentrations of naturally occurring acids transformed as the centuries passed into rich deposits known as “leonardite”. Growth Science® harnesses this wonderful gift of nature by providing humic acid derived from leonardite into a product we proudly call… Humic Tonic™.
