Abstract

The properties of soils affected by salinity and processes involving degradation of soil structure have been partly recognized. However, the effects of saline and sodic condition on physical and mechanical properties of soils, have been studied to a lesser extent. In this research, the effects of electrical conductivity (EC) and sodium adsorption ratio (SAR) on soils possessing various amounts of ORGANIC MATTER were assessed under laboratory conditions. The soils were collected from the Dasht -e-Naz of sari region in the north of IRAN, contained a uniform clay type, predominantly Illite. The major difference of the soils was their amount of ORGANIC MATTER content. The treatments consisted of solutions with given EC and SAR (two levels of ES;0.5and 4 dS/m and three levels of SAR; 0 , 5 and 15 ) with increase of SAR, the wet aggregate stability (WAS) decreased and the amount of dispersible clay (DC) increased .In similar SAR, treatments with higher EC exhibited lower DC. The order of average aggregate stability of soils were; virgin soils > soils under continuous cultivation of Festuca >soils under intensive cultivation with regular crop rotation>soils under continuous cultivation of Agropyron. The variance analysis of data showed significant differences (at 1%) between soil types, sampling depth, and SAR.
