Abstract

In the investigation has been stated, that up to time of coming into ear the barley had developed at nearly the same rate on the Sphagnum bog and the fen, which are differing distinctly with respect to nitrogen mobilization. However, the period development from the coming into ear to the ripening was nine days shorter on the Sphagnum bog than on the fen site. The temperature of air as well as soil had been largely the same on both sites during the period of development, from the coming into ear to the ripening. It appears likely, therefore, that the longer duration of this period on the fen site would account for the different mobilization of nitrogen.
