Abstract

The studies were conducted at two sites (a replantation and a virgin soil site). The following two combinations were used for each of the sites: control with no treatments applied and with the application of a mycorrhizal vaccine on the root balls of the plants at the time of planting. The four-year research showed that the way of soil usage had an influence on its biochemical properties, which were evaluated on the basis of enzymatic activity, which, except for the dehydrogenases, was at a lower lever in the replanted soil site. The use of a mycorrhizal vaccine did not increase the enzymatic activity in the replanted soil site, sometimes even lowered it. The content of organic matter defined as the total content of carbon and dissolvable carbon in the soil was higher at the replanted site than at the virgin soil one. The use of the mycorrhizal vaccine contributed to the increase of the content of the organic matter but only in the virgin soil site. The soil from the plantation growing on the virgin soil was characterized by the highest content of proteolytic bacteria and the highest respiratory activity.

Key words: enzymatic activity, indole-3-acetic acid, mycorrhiza, Vacccinium corymbosum.
