dc.description.abstract This paper focusedon the particular interestregarding the influence degree ofwastewater from pig breeding farms, applied systematically, during 15-20 years, on the degree of soil supply with nutrients and production increase of the crops cultivated on thistype of land. During long-lasting experiences, it was practiced the direct effect and systematic use of wastewater in a dose of 2400 m3 /ha. The data from systematic soil fertilization (1977-1992) allowedfindingout that thehumus content in the layer of 0-100 cmincreasedon average by 0.93%, the nitrate reached the values of 4-7 mg/100 g soil, which is 2-3 times higher than the maximum admissible concentration.Also,there were excessivelyincreasedmobile forms of phosphorus(8.4 mg/100 g soil) and potassium (181 mg/100 g soil) content, which exceedsthe optimal norm by 2 and 6 times accordingly. The extremely high K2O content of sodium enrichment led to moderate arable layer and low profile of the entire investigation. 15 years later, after the fertilization with wastewater (2007 year) finished, there remained a high content of humus,mobile phosphorus and potassiumwhich positivelyinfluenced soilfertility.Also, K2O content decreased by2.5 times and moderate solonetz soil became weak solonetz or non-solonetz arable and deep layer. en_US
