Its addition to soil can increase soil carbon, nutrient content, water retention, water-soluble nutrients, and beneficial microbial life. It is naturally derived from various plant materials such as hardwoods, grasses, and agricultural and forest residues decomposed at high temperatures. Harris biochar is made with 100% pure biochar with no fillers, additives, or colors whatsoever.
