Abstract:

The microorganisms within the soil, as they take part in the cycle of the nutrient elements necessary for the development of the plant, play an active role in the soil’s important elements of land efficiency as well as in the many chemical changes that occur in the soil. Most of the microbial activity in the soil is determined by measuring the activity of enzymes. The aim of this study is to explore the development of different soil in the same main material, different curvature and land use under semi-humid and moderate climate conditions and the change in the activity of the β-glycosidase enzyme. This study was carried out in the soil formed on basaltic main material in which different physiographic units are located within the mountainous location area located in the south of the Samsun-Bafra highway, Engiz Beldesi. The land is classified as Typic Haplustert and Lithic Ustorthent. In order to reveal the biological characteristics of the soil of the field of study, the β-glycosidase enzyme activity was evaluated and the four profiles of the soil samples were opened and taken along the Southwest-North-Eastern verified line of the β-glycosidase enzyme activity of 4.9-98.9 μg p-nitrofenol g-1 dry ball. It is determined that it changes. Furthermore, the statistical relationship between the activity of the β-glycosidase enzyme and different profiles, land use and height along the southwest-eastern line was studied and the effect of different profiles and different heights on the activity of the β-glycosidase enzyme in the soil was significant at 1 % (P=0,000<0.01), and the effect of different soil uses on the activity of the β-glycosidase enzyme in the soil was unimportant (P=0.670>0.05).
