Yakovishina T. Detoxication of the common black earth of northern Ukrainian Steppe contaminated by the heavy metals.

The reaction-response of the plants on the Cd, Pb and Zn toxic effect has been studied. The toleration line of the agricultural culture (millet>winter crops>peas>spring crops) has been determined. The possibility of the applica- tion K2CO3 and K2S has been proved on the common black earth with the tradition meliorant (chalk, biohumus, organo- mineral fertilizers). The complex method of the detoxication of the soil contamination by the heavy metals by means of combination of the fitostabilization and chemical binding. The recommendations have been worked out the detoxica- tion of the soil contamination by Cd, Pb, Zn by means of combination of the water solution K2CO3 application and growing of the fitostabilizator – millet (sort Mironovskoe 51).
