It is renowned for its capacity to enhance soil fertility and health by introducing necessary nutrients and encouraging the development of advantageous microbes. Leonardite has many beneficial uses, including enhancing soil structure, water retention, and aeration, as well as enhancing the soils ability to retain nutrients.

This product has perhaps the highest concentration of both humic and fulvic acids available on the market. Increases nutrient retention in fast draining soils. Aggregates soil particles for improved drainage and stability. Buffers sodic or saline soil conditions reducing yield drag
