Raw Humates (predominantly Lignite) are a slow-release, insoluble source of humic and fulvic acids in their unextracted, natural form. Sourced from Australia's premium humate depos its — regarded as the best globally — this is the raw ore that purified humic and fulvic acid products are chemically extracted from, offering far greater long-term availability of these crucial organic acids at constant background levels. Unlike soluble humic acid extractions, which require regular reapplication and carry residual potassium hydroxide from the extraction process, raw humates are insoluble and lock their benefits into the soil for extended release. They're also naturally acidic rather than alkaline, making them ideal for balancing the pH of alkaline fungal-dominant composts without harshly affecting soil biology. The bulk carbon content feeds long-term soil structure and microbial activity — benefits that soluble extracts simply can't replicate. Show more
