Saisonale Dynamik von Ct und Nt im Boden unter Winterweizen mit nachfolgender Zwischenfrucht

Summary in the original language of the document

The aim of this work was to study seasonal changes of topsoil Ct and Nt contents in
comparison with Ct and Nt mass changes. The survey was carried out under winter rye
with succeeding catch crop. A special experimental design was chosen to minimize
space/time interactions and prevent disturbance of sampling points at the same time.
The observation of mass changes instead of content changes substantially improved
the analytical quality of results in this study, which was in line with findings from the
literature. It is concluded that considering bulk density should therefore be
recommended as a standard procedure in surveys of soil Ct and Nt dynamics.
