ABSTRACT
The activity of enzymes is necessary for the operation of all bio-transformation in the soil, and therefore the enzyme activity used as a sensitive indicator of biological activity of the soil. The quantity of factors influence the activity of soil enzymes therefore it is necessary measured values given in relation to the physical, chemical and biological characteristics of the soil. In the years 2012 - 2013 in the locality of the dry polder Besa the biological activity of soils were observed and evaluated by the selected biological and physical characteristics. Soil samples for determination the selected properties were taken from depth of 0.0 - 0.6 m at 0.2 m from four profiles. From the biological properties of the activity of urease, acid and alkaline phosphatise were investigated. Experimental data were evaluated by statistical methods. Values of activity urease ranged from 0.02 to 0.46 mg [NH4 ± N g -1 24 h-1]. Values of activity acid phosphatase from 26.32 to 115.19 [μg P g-1 3 h-1], values activity of alkaline phosphatase ranged from 10.53 to 82.27 [μg P g-1 3 h-1]. Statistical testing, we found the correlation dependence between phosphatases and physical properties and phosphatases each other, except for the content of grains I. cat., the soil urease we didn’t find a statistically significant correlation in relation to the selected parameters.
