In the conditions of a vegetation experiment with rape the author ascertained that an increase of the dose of ammonium nitrate is accompanied by an increase in copper content in the tops of rape. The highest count of copper featured the plants fertilized with ammonium nitrate, a lower one - with sodium nitrate, and the lowest one - with ammonium sulphate. Liming lowered the content of copper in leaves of rape fertilized with sodium nitrate
