Humic Acid (soluble powder)

  • 100% ORGANIC

Humics are the most natural and organic way to provide plants and soil with a concentrated dose of essential nutrients, vitamins and trace elements. They are complex molecules that exist naturally in soils, peats, oceans and fresh waters. The best and most concentrated sources of humic acids are derived from a compressed organic compound known as Leonardite derived from fresh water deposits. Leonardite is the completely decomposed remnants of living organisms derived from 70 million years of humification. Like manures and other organic compounds are used to build richly fertile compost, so too Leonardite is the end result of nature’s own composting derived at a time when the earth had minimal pollutants. As a comparison, Peat is derived from only a few thousand years of decomposed organic matter. Plant Dr Humic will help you grow plants like never before.
