        abstract = {Common humus balance methods give distinct inexact results (KOLBE & PRUTZER 2004) and do not meet nowadays requirements (KOLBE 2006b). Outgoing from the method of K?RSCHENS et al. (2004) an improved, site adjusted, semi-quantitative method was developed for manual use in agricultural practice and consultation. }
