An estimated 80 percent of aboveground issues in trees are caused by issues below ground, namely problems related to roots and soil. This has led to an increased interest in the care of belowground features, particularly to overcome soil compaction and fill materials lacking organic matter. Biochar is a form of charcoal added to soil to achieve a desired improvement in soil functions. (A, U, M, T, Bs, Bm)
