Phosphatase enzyme activity in different soils formed on bazaltic parent material under semi humid climate conditions
Abstract
Soil enzymes have an important role in determining the function of microorganism in soil ecosystem. In addition, the enzyme activities give much knowledge on the biochemical processes occurring in soil. Therefore, soil enzymes such as dehydrogenase, phosphatase and urease are indicators of soil biological productivity and activity. This study was carried out to determine phosphatase activity in different land use of Bafra-Engiz Basin, Samsun and to investigate the relations between soil pedogenetic processes, land use, elevation and phosphatase activities. For this purpose, soil samples taken from the four soil profiles classified as Typic Haplustert and Lithic Ustorthent. The analysis results related to phosphatase activity of soils in the study area changed between 8.1-177.3 μg p-nitrophenol. Moreover, according to statistical analysis results different profiles and different elevation were found to be important at 1% level of effect on phosphatase enzyme activity in the soils. Finally, it was also determined that the effect of different land use type on the activity of phosphatase enzyme activity in the soil was insignificant as statistically.
