The main objective of this research was to investigate the effect of the treated and composed solid sludge from waste water treatment stations on the yield and quality of tobacco. Quality characteristics of the sludge were analyzed, as well as its impact on improving the soil properties as unrivaled environment in agricultural production. Field experiments were set for three consecutive years (2011-2013), in two locations with four variants as follows: variant without fertilization (control), fertilized variants with 10 t/ha, 20 t/ha and 30 t/ha. According to analysis of the sludge it was found that it contains a high percentage of organic matter (>20%) as a good basis for improving lean and poor in organic matter agricultural soils. After three years of the field experiment it can be concluded that sludge has a positive impact on soil quality characteristics. It slightly increases the content of humus and pH of soil, and maintains the content of available phosphorus and potassium. The yield of tobacco was increased so thus
the average price and the revenue from the unit area. Usage of the sludge does not deteriorate the quality properties of the produced raw tobacco.
