| Popis: | Effects of de-icing salt on dehydrogenase, urease, alkalihephosphatase and arylsulfatase activity ofOL andAh-horizons of a moder and a mull soil were investigated using a field experiment. Additions of 2.5 kg m−2 and 5.0 kg m−2 of de-icing salt reduced activities of most enzymes within four weeks. Eleven months after salt addition there was nearly no reduction of enzyme activity to be measured on salt treated soils. The percentage of reduced enzyme activity was generally higher in the moder soil. It was concluded that reductions of enzyme activity were due to decreases of microbial activity and not to inactivation of enzymes. |
