Changes in Soil Microbial Biomass and Activity under Different Land-Use Types in Bartın, Northwestern Türkiye
Abstract
The aim of this study was to examine microbiological soil properties under three different land-use types within the borders of the Ulus Forestry Operations Directorate in the Bartın Stream Basin of Northwestern Türkiye. Samples of topsoil were taken to determine soil microbial biomass carbon (Cmic) and basal respiration (microbial respiration). Cmic contents of the topsoils belonging to the different land-use types ranged between 219.87 and 777.09 µg g–1. The highest average Cmic, basal respiration, and metabolic coefficient (qCO2) values of the soils were noted in the black pine forest site, whereas the average Cmic/Corg percentage was the highest in the agricultural site. Moreover, these characteristics were found to be statistically different (p < 0.05) among the black pine, rangeland, and agricultural site topsoils. This demonstrated that microbial properties, in particular, are potential biological indicators for assessing ecological changes brought about by management practices and usage of the land.
期刊介绍：
Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
