The sodium humate influence on the test-culture morphometric indices in the conditions of soil pollution by heavy metals

It is established by the authors’ research that the nature and strength of the heavy metals influence on the plant growth are primarily determined by their concentration in the root environment. In the presence of high concentrations they inhibit the growth processes. The use of sodium humate heavy metals as detoxicant improves all the indicators of spring barley primary growth, and more effective is the humate concentration 0,30 g/kg of soil.
