Study on litter quality two rangeland Species Artemisia sieberi and Salsola dendroides and its effects on soils properties in Til-Abad (Golestan province)

Litter of plant is the best factor in soil stability and conservation and as a result of its decomposition the soil organic matter increases and amends the chemical properties، increasing plant production. The aim of this research was to study litter quality and feet soil’s Artemisia sieberi and Salsola dendroides species on carbon، nitrogen، phosphorous، potassium and respect carbon/nitrogen of in region Til-Abad of Golestan province. After identifying habitat of these two species in Til-Abad، at the end of growing season، litter and soil in mentioned species were collected in this site، sampling was conducted randomly – systematic. Then along each transect sampling litter and soil from a depth of 0-30 cm from each species site and sampling was done in control site too. Then the properties of nitrogen، phosphorus and potassium in the soil were measured. Analysis was performed using T-test. Results showed the amount of P and C/N in the feet soil and C، K، C/N in the litter of Salsola dendroides were the highest but Ar. sieberi species is the best species in soil productivity of this region.
