Soil
organic carbon plays a vital role in the arid and semiarid regions. This study
aimed to predict and map soil organic carbon content at soil depth intervals of
0-0.3 m, 0.3-0.6 m, 0.6-0.9 m, and 0.9-1.2 m in alluvium soils along Blue Nile
and River Nile, Sudan. Ordinary kriging (OK) technique was used as a
geostatistical tool and applied to model the spatial variability of soil
organic carbon in the study area. A total of 38 soil profiles were excavated in
the study area and 152 samples from the four depths intervals were collected
for determining organic carbon content. Results revealed that, the spatial
autocorrelation for the different soil layers was moderate to weak with a
nugget to sill ratios ranging from 0.21 to 0.86 suggesting their controlled by
both intrinsic and extrinsic factors. The root mean square error standardized
(RMSE) of the predictions ranging from 0.79 to 0.83 indicating that the model
which generated by ordinary kriging was correctly estimating the variability of
soil organic carbon in the study area.
