Abstract
Studies of the chemical composition of processed waste water mud were carried out. It was concluded that it fully complies with the properties of wastewater mud and is suitable for biological reclamation. Wastewater use as a soil fertility enhancer and crop yields improver was shown. Presentation of the field studies results on the cultivation of safflower, as well as those of monitoring of soil samples for the content of macroelements, organic matter and heavy metals associated with the introduction of sediment as an enhancer. It was proved that after the first year of sludge application, the content of humus and macroelements in soils increases during next three years, as well as the yield of safflower increases.
