Table 4. A comparison of equivalent calcium carbonate determination by two methods in soil samples of Kurdistan Region
governorate, data represented as (mean ± SE).
Governorate Calcimetric Method Titrimetric Method Differences
Erbil 169.62 ± 14.78 169.47 ± 14.61 0.15
Sulaimaniya and Kirkuk 139.90 ± 18.22 140.40 ± 18.15 –0.50
Duhok 239.33 ± 14.61 237.79 ± 14.60 1.54
have the same scientific base. The differences shown in
(Table 4) between mean values of E-CaCO3 content of
soil samples measured by the two mentioned methods are
non significance. A little difference observed between
two methods for soil samples of Erbil, Sulaimaniya-
Kirkuk governorates that reached to 0.15 and −0.5 re-
spectively. While the differences was 1.54 unit for Du-
hok soil samples. Generally, soil samples for E-CaCO3
content were increased gradually from Sulaimaniya-
Kirkuk, to Erbil toward Duhok governorate.
