ESTIMATION OF PHYTOTOXICITY CONTAMINATED BY DIESEL FUEL OF PEAT SOIL IN REHABILITATION BY COMPLEX MELIORANT SAPROSIL
The results of long-term field experience on the study of the effect of the complex meliorant Saprosil on the phyto- toxicity of peat soil contaminated with diesel fuel are presented in the process of its rehabilitation. It has been exper- imentally established that a complex ameliorant provides a reduction in the phytotoxicity of soil contaminated with diesel fuel. At a pollution level of 2.5%, the use of a dose of a complex meliorant of 5 tons/ha eliminates the phytotoxic effect: the difference in yields in the control and in the experimental variants is not significant. An increase in the dose of introducing a complex ameliorant into the soil increased the neutralization of the phytotoxic effect from the action of petroleum products, the best result was reached when using Saprosil at a dose of 10.0 tons/ha. The complex ame- liorant, in addition to the pronounced effect of reducing phytotoxicity, provides a fertilizing effect: when applying a dose of 10 tons per hectare, the yield increases by 1.36 times in comparison with the control.
