تأثير التعرية الريحية في تغاير عمق التربة و بعض خصائصها الكيميائية في منطقة شرق الرزازة

الملخص EN

The study aims to study the effect of wind erosion and wind speed in changing the depth and some of the Chemical properties in the East of Razazah.

A strip transeet of 40km long and 3km wide was selected.

Three modelling sites were set on dimension 10, 25 and 40 along the transset points1, 2 and3 Respectively.

The result showed an increase in the depth of the soil at site 3by 7.7% compared to site 1and that the values of the reaction levels for the chain of the studies series were distributed within the range (7.3-7.5).

The electrical conductivity values ranged from (2.45-3.43).

The values of the exchange capacity of the cations were between (5.2-15.9 cent.

Mol, Kg-1).

The gypsum content is distributed in the area's soil with a range of (159.1-227.1gm kg-1).

The carbonate equivalent showed a difference in the horizontal and vertical distribution in studies breeding isolates and the soil content of the component was distributed with range of (87.0-143.0 gm kg-1).
