To achieve high productivity in growing crops, it is required not only to feed them in time with fertilizers, but also to provide for the reliable protection against weeds. In the large household scale, it is practically impossible to do it manually. Therefore, chemical protection agents - herbicides come to the aid of the agrarians.
To ensure the healthy growth and high productivity, corn, in addition to the main macroelements, requires a number of other minerals. Small amounts of them are required, but this in no way diminishes their importance for crop development and productivity formation.
