PHYTOTOXICITY OF SOD-PODZOLIC SOILS IN THE ZONE OF INFLUENCE OF LIVESTOCK COMPLEXES AND POULTRY FARMS

Abstract

The article presents the data of phytotesting of sod-podzolic soils with regular application of pig manure effluents, liquid manure of cattle and litterless bird droppings using three test cultures - spring barley, winter wheat, and corn. It was established that the studied soils do not have a phytotoxic effect on the parameters of growth and development of test cultures: seed germination relative to soils without loads was at least 90 % with inhibition of sprout length not more than 11.6 %, roots 12.7 %. The total toxicity of the studied soils corresponds to the V class of toxicity (norm), i. e. the value of the test functions is at the level of soils without loads.
