Soil factors affecting the distribution of four salt tolerant range plants in eastern Azarbaijane province (Gharakhlar)
Correct management of a range land is on the basis of ecological principals.Understanding the ecological processes is the main term of management Mesdaghi (2002).Environmental variables consist of complex reactions between environmental variables and plants (canopy cover and density) Jangman (et al, 1987).Various plant types have correlation with soil types.Zahran (et al,1992) said that in saline areas salt, soil texture and organic carbon are the most important factors in distribution of plant communities.The results showed that index plants were the presidents of ecological soil factors.Layon and Sagers (2003) in misiyory of United states, by using ordination method (CCA, DCA), came to the conclusion that there is a little correlation between plant vegetation.The goal of this research is determination of relationship between four saline range plants parameters (canopy cover and density) and physico‐chemical soil factors to develop range lands, managing the vegetation and conserving the soil and water.
