Effect of Variety and Fertilizers on the Trace Element Composition of Radish
In studies on meadow-Chernozem soil of the Omsk region the influence of the variety and macrofertilizer on the yield of radish and concentration in the roots of copper and zinc. It is established that nitrogen fertilizers with insufficient levels of nitrate nitrogen in the soil, increases the copper content in the roots of all varieties. At the same time, the content of zinc by the action of nitrogen in the roots to Heat, Radius, Rebel, Tarzan is reduced in the roots Shcaro and Beauty varies slightly, but Dungan increases. With increasing doses of potassium from 45 to 90 kg/ha copper concentration was reduced to 1.09 at 1.58, and zinc - of 1.07-1.95 times.
