Özet
Conversion of a native ecosystem can impact the nature and dynamics of organic carbon (C) fractions. The goal of this study was to determine the effects of cultivation and monoculture wheat production on soil organic C and biological C fractions compared to a previously flooded native pasture in northern Turkey. Soil samples were collected from four randomly selected locations of each management system. Some soil chemical [pH, calcium carbonate (CaCO3), total nitrogen (N), and organic C], physical (sand, clay, and silt), and biological properties [microbial biomass carbon (MBC), mineralizable C, and mineralizable N] were measured. Conversion of pasture to cultivated land slightly increased soil pH, but CaCO3, total organic C (TOC), and N contents were significantly (P < 0.05) decreased with cultivation. Total organic C and N contents were more than three times less in cultivated soils compared to pasture. Microbial biomass C was significantly decreased (P < 0.05) with long-term cultivation, and the greater seasonal fluctuations were measured at the surface of both ecosystems. The greatest level of potentially mineralizable C was observed in the pasture rather than the cultivated soil, but the proportional distribution of mineralized C to TOC was greater in the cultivated soil. These results suggested that the long-term cultivation (15 years) of previously flooded native ecosystems increased C mineralization and resulted in 72% C loss at the surface soil. Cultivated soils have a greater potential to restore atmospheric carbon dioxide (CO2) if proper cultivation and management systems are used. © Taylor & Francis Group, LLC.
