This study evaluates the effect of polluted irrigation water on the count of ammonifiers and the proteinase activity of soil under red clover. The experiment was conducted in the greenhouse of the Faculty Agronomy in Čačak in pots containing two soil types (alluvium and vertisol) in five replications. One treatment involved irrigation with water collected 200 m downstream of the main industrial and municipal wastewater collector in the City of Čačak, and the other treatment was irrigated with clean tap water. Their effect on the above soil biological parameters was determined three times during the red clover growing season. The obtained results suggest a depressive effect of polluted irrigation water on ammonifier counts and proteinase activity of the soil. The decline in ammonifier counts was higher in vertisol, whereas proteinase activity was ore pronounced in alluvium.
