Resumen :
This study aims to assess the amount of
organic carbon stored in soils, as it is an intention of
knowing the sustainable soil management, by using
two common methods for determining soil organic
matter (SOM), namely oxidation with acidified wet
dichromate (Walkley–Black method-WB) and loss on
ignition (LOI). The study was carried with soil samples
collected from a depth of 0 to 30 cm in the Saharan
arid region of Ghardaïa (Algeria), with different
land uses: agricultural, forest and pastoral. The results
obtained from the LOI and WB methods were subjected
to statistical analysis, and the relations between
both methods were tested to investigate their relationship.
The mean percentage of SOM values were 1.86,
2.42, 1.54 by using LOI, but, lower values of 0.34,
0.33, 0.36 were determined by using WB method,
for agricultural, forest and pastoral soils respectively.
A weak linear relationship between the two analytical
procedures was obtained (
R2 of 0.19 and 0.13 for
agricultural and forest soils), while a medium relationship
(
R2 = 0.65) was found for pastoral soils
when using linear adjustment. However, the opposite
behaviour was found when we use the logarithmic
adjustment. The study outcomes indicated discrepancies
in the measurements of SOM values between
the two methods, been higher those estimated with
LOI. Finally, in order to identify the best methodology
to measure soil organic matter in arid soils, more
research is required in these extreme arid regions as
they are a gap in world soil organic matter maps.
