Mineralize C and N contents and organic matter quality can be influenced by soil management, and vary by the slope of sampling location. Soil organic matter quality can impact mineralization of organic matter and eventually C sequestration. The objective of this study was to determine the effects of land management and different slopes on mineralizable C and N contents at high elevated location. The study was conducted on three different adjacent land uses (agricultural, grassland and forest) at 1500 m elevation in Tokat, Çamlıbel province. Soil samples were taken from 0-10, 10-20, and 20-40 cm depths and also soil samples were taken through slope in agricultural field. The greatest mineralizable C was measured in forest and followed by grassland and agricultural field. The mineralizable N content was similar in the three land uses. Mineralizable C content increased from upland to lowland. However, mineralizable N content was similar through the slope.
