Abstrakt
Since 1997 the exact field experiment with crop rotation under conventional and protection soil tillage ploughless from 1995 has been conducted at Prague-Ruzyně site, where soil microbial activity was tested in both variants of soil tillage. The soil samples were taken in autumn from three depths of soil. The results show the positive influence of protection tillage, especially in variants where soil was supplied with organic matter, on the revival of upper layer of topsoil by microorganisms.
