Abstract:

The enrichment of organic carbon in the soil is an effective strategy in the fight against climate change by reducing the concentration of C in the atmosphere. The aim of this study is to identify and map the carbon storage potential of the soil under different land uses in the Upper Dicle Pool. The work area, which covers an area of approximately 8700 km2, is divided into 5 km x 5 km grids, and a total of 210 damaged and undestroyed surface (0-20 cm) of the corner point of each grid is taken. In order to determine the variability of land characteristics at a distance of less than 5 km, 42 land samples were taken from a distance of 250 m, 750 m and 1750 m between the corners of the two follow-up square grid. The organic carbon and volume weights of the soil samples are determined and the map of the soil organic carbon stock (TOKS) of the work area is prepared by calculating the carbon stock for each point. It has been determined that the use of land has a statistically significant impact on TOKS. The amount of TOKS in the study area ranges from 8.06 to 66.68 Mg ha-1 and the average amount of TOKS is 30.33 Mg ha-1. The highest amount of TOCS among different land uses was 44.33 Mg ha-1 in forest areas, while the lowest amount of TOCS was 28.91 Mg ha-1 in land plants. In particular, overwhelming fertilization and traditional soil processing and harvest waste burning in rural areas have been determined to have a negative impact on TOKS in the Upper Dicle Pool.
