Study of Atriplex canescens effects on soil properties in different depth

In order to increasing productivity and achieving to reclamation objectives, it is necessary to recognize relationship between soil and plant. Selection of adaptable and resistant plant with arid conditions depends on distinguish of ecological needs of them. Plants have special effects on there habitat and study of these effects can be useful in planning projects.In this research, we try to identify Atriplex canescens effects on physico-chemical properties of soil in different layers in Qom. Split plot plan was used for sampling and analyzing. Cultivated and natural lands were considered as between factors and different depths [(0-10),(10-30),(30-60) cm] as within factors. Soil properties including texture, EC, acidity, nitrogen, phosphorous, potassium, organic matter, sodium, calcium, magnesium, chloride, carbonate, decarbonate were measured. Results show that Atriplex canescens increased phosphorous, potassium, acidity in surface layer more than other layers in cultivated area.
