Potassium Humate 98% humic acid flake is a dark black humate derived from leonardite with a high content of humic acid. When applied to soils, it helps break compacted soils, allowing for improved water penetration. For sandy soils, our humic acid adds essential organic material necessary for water retention and enhances the sandy soil's ability to retain vital plant nutrients without leaching.
