Influence of Sodicity and Salinity on the Mechanical Properties of two Italian Soils

The results have shown that different soils may have a very different response to the treatment with brackish water. The soil sensitive to the saline action greatly reduced its plastic limit and consequently its workability. This is also shown by the significant increase in shear resistance. In addition, the slope of the line used for liquid limit (LL) determination, expressing the sensitivity of the soil to the moisture content, can effectively be used as an index of sensitivity to sodic soils.
