Wilchem’s liquid Humate 450 is an acid and alkaline soluble Humic Acid. It is based on modified potassium humate derived from lignite ore. Humate 450 provides superior solubility over the entire useful pH range and can be mixed with basic and acid liquid fertilisers. Wilchem’s liquid humate meets all the requirements of regenerative agriculture to improve plant health and soil function. “Humic Substances aren’t the only universal depot of carbon and energy but possess a big biological potential that makes them an analog of ATP for biosphere” Chuko, 2008
