Influence of organic fertilization and liming on tilling of plants stretches was studied in several subsequent years. The experiment was set at rout E-30 on the ground of the Experimental Station in Zawody on the soil polluted by cadmium and lead. The source of pollution in car traffic of large investigation. The experiment investigated the influence sequent fertilizations with farmyard manure, with straw rye and with green manures in form of winter inter crops (winter rye, winter vetch) and of liming soils on content of available cadmium and lead content in beetroot variety Red Sphere. Beets were tilled in the second year after organic fertilization and liming. Organic fertilization essentially lowered the content of available cadmium and lead in soil and roots of granary red beets. The lowest content of cadmium was found in soil and beets brought with straw in quantity 4 t/ha, and the lowest content of lead after fertilization with winter second crops: with vetch winter and with rye. Soil and comparison to that found in soil and beetroot tilled without liming
