An organic liquid humic concentrate, derived from the finest, richest, and purest source of humic acid in North America and arguably the World. This humic acid source is a weathered type of oxidized sub-bituminous coal rich in humic substances. The Humic source is similar to the commonly found Leonardite (lignite coal), BUT contains a higher concentration of Humic substances and significantly lower levels of ash and heavy metals, such as lead, arsenic, and mercury. Diamond Grow Humic[K] helps improve soil structure (whether sand or clay based), stimulate the activity of soil biology, make nutrients more available and aid in the formation of more stable humus.

OTHER HUMATE PRODUCTS: Diamond Grow Humi[K] water soluble powder (WSP) and water soluble granule (WGS).
