Productivity of agrocenoses of oat in conditions pollution of heavy metals of gray forest soil

Abstract

Object. To set possibility of the use of sowing of oats the shelled and naked for phytoremediation of soils contaminated with zinc, lead and cadmium in condition of right-bank Forest-Steppe. Methods. Field trials, laboratory testing, mathematical-statistical methods. Results. Conducted experiments affirm that the cultivation of different varieties of oats artificially contaminated with heavy metals ecotopes gray forest soils has led to changes in their quantitative, qualitative, toxicological characteristics of harvest, and also determination of the possibility of using grain. Conclusions. It is established that in condition of right-bank Forest-Steppe on territory with content in the grey forest soil of lead up to 1,000 mg, zinc up to 500 and cadmium up to 20 mg per kg sowings of oats shelled (variety Neptune) and oats naked (variety Solomon) show high tolerance to pollution, so it is possible to conduct a phytoremediation with their use, however the change for the worse of toxicological grain characteristics of these crops makes impossible its use in food and feed purposes.
