WebRoot turnover, in units of yr-1, is the ratio of Annual Belowground Production to Maximum Belowground Standing Crop. This approach is a modification of the model initially proposed by Dahlman and Kucera (1965).

WebNov 18, 2016 · Coarse root biomass (CRB) is commonly estimated by using destructive techniques, including high-pressure air spading, soil excavation, and coring [Butnor et al., 2003]. These methods allow direct observation of root networks but are time-consuming, labor-intensive, and yield tree or plot specific data.
