The intensity of accumulation of heavy metals in grain of winter wheat depending on predecessors

Abstract

The author investigates the effect of longstanding grasses: alfalfa seedlings, clover raccoon, sandstone espaces, white humpback salmon, grizzly beef, oriental goat and corn for silage as predecessors of winter wheat for the concentration of heavy metals: lead, cadmium, copper and zinc in the soil and grain of culture. The coefficient of accumulation of heavy metals in wheat grain of winter after the studied predecessors has been calculated.
