The influence of three machines (digger, bulldozer and cultivator) used for the windrow cultivation was monitored in relation to soil properties. The results were compared with those obtained in scarified control plots in a clear-cut area in the Krusne hory Mts., Czech Republic. Windrow cultivation led to an increase in cation exchange capacity, especially due to an increase in Ca2+ and Mg2+ concentrations. It led also to the stabilization of N-NH4 concentration. It did not optimize the C/N ratio, soil maximum capillary capacity and porosity. The mechanized windrow cultivation in the conditions of decreased air pollution load generally appears as a good technology for revitalization of degraded sites because it provides more optimal trophic conditions for the forest tree species growth than windrows or scarified sites.
