Biochar is a soil amendment produced by the process called pyrolysis, which is the burning of biomass in a limited oxygen environment.Potential benefits of biochar in sandy soils include addition of organic matter, nutrient retention and recycling, enhanced microbial activity, and long-term carbon sequestration.Adoption and use of biochar by vegetable growers has been slow, because information is lacking on how biochar will affect crop production on a long-term basis.
