Resumo:
The aim of the study is to contribute to the knowledge and the identification of the main physical and chemical characteristics of the soil that affect the structural stability of soil types forming the soil cover of the plain of Sidi Bel Abbes region for agricultural use by excellence. Structural stability is an indicator of the cohesion of soil aggregates. This is a parameter that expresses the ability of soil aggregates to resist degradation in general the impact of rain or excess water. Measuring the structural stability makes it possible to evaluate the sensitivity a soil crusting and erosion. The results showed that soils subject of our study are stable and very stable with a slight difference. We have a statistical study made it possible to establish a correlation between the structural stability and other physical and chemical soil parameters measured )fersiallitic red soil and brown calcareous soil( such as organic matter content, the rate of total limestone and soil texture, to better explain the stability or instability of the soil structure and to establish a relationship between these parameters and the structural stability. // Keywords: Sidi Bel Abbes, chemical characteristics, physical, structural stability, soil, plain, fersiallitic red soil, brown calcareous soil
