Humic Acid is a natural dark-brown to black organic substance formed over thousands to millions of years from the decomposition of plants and animals in soil, with the highest concentration found in leonardite ore. When applied to soil or sprayed on plants, humic acid loosens compacted soil, improves water and nutrient retention, powerfully stimulates white root growth, and greatly enhances the plant’s ability to absorb nutrients while building strong resistance to drought, salinity, heat, and cold.
As a result, plants stay dark green longer, suffer fewer pests and diseases, produce bigger, sweeter, better-colored fruits with higher yields, and farmers can safely reduce chemical fertilizers by 20–30 %.
