The effect of different land uses on soil respiration was investigated in winter 2009 in black locust, grassland, apple orchard (apple trees and grass) and walnut areas in Seyitler Village, Artvin, Turkey. Soil respiration was measured in December by the soda-lime (NaOH, KOH) technique. Mean daily soil respiration ranged from 0.29 to 1.26 g C m-2 d-1. Mean daily soil respiration in black locust was greater than the other areas. Soil respiration was different in the investigated four vegetation types. Established difference was non significant and correlations were negative among soil respiration, soil moisture and soil temperature. These results show that black locust has higher soil biological activity compared to the other areas in this season.
