Studies carried out in the Transcarpathian region of Ukraine with the application of sewage sludge as fertilizer for Silphia prinosanolista showed that the use of 20-40 t/ha of fresh SS and composts based on it with cereal straw creates a different agrochemical background of alluvium, compared to the application of an equivalent norm of mineral fertilizers, and causes a change in the content of bioavailable forms of the main nutrients - nitrogen, phosphorus, and potassium in the soil layer 0-80 cm.
Significant differences in the content of mineral and alkaline hydrolyzed nitrogen compounds in the upper layer of 0-40 cm of alluvium were established. Application of increasing (20-40 t/ha) rates of sewage sludge, as well as their composts with straw and a compensatory amount of mineral fertilizers, contributes to a reliable increase in the content of ammonium compared to the option without the application of fertilizers and the option with an equivalent dose of mineral fertilizers.
