Vegetable cultivation is an example of intensive agricultural production. It is contributing to changes of physico-chemical properties and the biological productivity of the soil. The aim of our examinations was to determine the influence of vegetable cultivation and the intensive fertilizing and soil nurturing associated with it on selected soil physico-chemical properties and the activity of urease and invertase. Findings of conducted examinations indicated the very diversified but always inhibited influence of intensive cultivation of the examined soils on the activity of urease and invertase. Invertase and urease activities strongly positively depended above all on the content of organic substance. Urease activity was the lowest in the soil under foil tunnels, and invertase activity in soils, on which they were growing vegetables in ground, after dismantling foil tunnels.
