Different soil samples from five tilled areas of Jibou (Salaj County, Romania) have been physico-chemically and enzymologically studied. Several physico-chemical parameters of tilled soil from these sulphurous areas were determined: pH, conductivity, humus and different mineral ion contents. Also, in the soil samples, the following enzymatic activities have been quantitatively determined: actual and potential dehydrogenase, phosphatase and catalase activities. In all soil samples all enzymatic activities have a uniform behavior, without big differences between the five sampling zones. Also, the physico-chemical parameters were very uniform, as compared to the other sampling sites. The enzymatic potential was appreciate by the enzymatic indicator of soil quality (EISQ), calculated on the base of these enzymatic activities. The EISQ values were good, between EISQ = 0.574 and 0.635. The granulometric analysis of the five soil samples classified them as loamy-clayey soils.
