چکیده
Soil salinity is one of the problems threatening agricultural lands. Parts of this phenomenon are related to geologic formations and saltpans, while some major factors are resulted from irrelevant agricultural activities, issue of irrigation, and improper cultivation systems which lead to increase in soil salinity. To avoid such consequences that would end up with ecosystem degradation, suitable management of these lands is indispensable. A research was conducted in agricultural lands as well as in rangelands of Kermanshah province (in split plots with three replications) to analyze EC and SAR in the different layers of soil. The results indicated that there are significant differences among the treatments. Duncan analysis showed that the highest EC and SAR are related to deeper layers of soils in steep slope rainfed lands of Paveh, not suitably treated, while from more the top soils of gentle slope rainfed lands of Kermanshah benefit suitable treatment and management.
