Location map of the study area. To estimate carbon (C) sequestration, a subbasin covering a total area of 1,414.7 km², including 14,758 ha of wheat lands, was defined. Landsat-8 Operational Land Imager (OLI) bands 4, 5, and 6 were used for the calculation of NDVI through random forest (RF) supervised classification processes to obtain detailed information on wheat-based cropping systems. The map was created in ArcGIS Pro using the SSURGO dataset as the primary source for identifying the dominant soil types.
