SOIL ENZYME ACTIVITY AS AN INDICATOR OF CHANGES IN FOREST SOIL

摘要

The aim of the study was to determine the activity of dehydrogenases and urease in forest soil before and after the blowdown. The research was a continuation project which was carried out in 2007-2010. The research was carried out in the Przedborz Forest Inspectorate. Statistically significant differences in enzyme activity were observed in the soil taken before and after the blowdown. The lowest differences in enzyme activity were detected on the BM22, LM 35 and BM36 plots. Our results show that trees and shrubs have an impact on the soil properties. The enzymatic activity of the soil in the humus horizons may be used in estimating change in the soil.
