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

The inhibiting action of the heavy metal ions on the summer barley sowing qualities is established. The availability of the sodium humate in the soil as the detoxicant of cadmium and lead promotes the increase of the grain germination energy and laboratory viability, the detoxicant concentration of 0,30 g/kg of the soil appeared to be more effective.
