Diamond Black is derived from a new natural source of humic acid: wood! This new technology provides a clean product, free of residues.
Diamond Black is made of pure ligno-humates and contains an exceptionally high percentage of plant-active humates. These organic compounds improve nutrient absorption, stimulate microbial activity, promote soil structure, increase nutrient retention and reduce water usage in the landscape. Additionally, Diamond Black can also be utilized as an additive for making compost.
