VARIATION OF DEHIDROGENASE ENZYME ACTIVITY AND DIFFERENT PEDOGENETIC DEVELOPMENT ON WEATHERED BASALTIC TOPOSEQUENCES
Journal Title: Black Sea Journal of Agriculture - Year 2018, Vol 1, Issue 4
Abstract
The aim of this study is to examine the changes in dehydrogenase enzyme activity in different pedological development soils formed on the same parent material, but with different slopes, land cover and land use under semihumid climatic conditions. It was carried out on the soil formed on the basaltic parent material in different topographical positions within the Dağköy area of Engiz district, which is located at the south of the Samsun-Bafra Highway. In this study, dehydrogenase enzyme activity was assessed in order to reveal the biological properties of the soil of the study area and it was investigated the dehydrogenase enzyme activity in terms of soil biological property. For this aim, six soil profiles formed on weathered basaltic parent material and located on toposequence of north-south transect were described according to genetic horizon and classified as Lithic Ustorthent, Vertic Haplustept, Typic Haplustept and Typic Haplustert. It was determined that the dehydrogenase changed between 0.073-1.170 µg TPF in soils taken from each profile. In addition, when the statistical relationship between dehydrogenase enzyme activity and different profiles, land use, and elevation along the north-south transect was investigated different profiles and different elevation were found to be important at % 1 level of effect on dehydrogenase enzyme activity in the soil. Also the effect of different land use patterns were found to be important at % 5 level on the activity of dehydrogenase enzyme in the soil.
