BOONE — The Appalachian State Nexus Project experiments continue to advance agricultural innovations with biochar to help local farmers. Biochar is a charcoal-like material produced from plant material such as grass, agricultural and forest residues that  produce carbon-rich material used for agriculture and horticulture purposes. 

Adding biochar to soil increases surface area, pH, plant nutrient availability, and enhances water-holding capacity, according to Appalachian State researchers. It also can sequester carbon in the ground for extended periods of time, which may otherwise find its way into the atmosphere as CO₂ or methane.

The qualities of biochar vary depending upon the material it comes from — timber slash, corn stalks or manure.
