Abstract
Plant litter is an important factor inimproving soil quality and plant biomass production in rangeland ecosystem. The aim of this study was to measure and compare the litter quality in three range plant species i.e. Artemisia aucheri, Centaureavirgata and Scariolaorientalis and its relationship with soil physical and chemical properties in Haj Beygi rangeland, Torbat-e Heydarieh. Systematicrandomized sampling method was used with three transectsandone square meter quadrat. In each quadrat, litter was sampledforeach species separatelyand soil was also sample in0-15 and 15-30 cm depths exactly under individual plant canopy. Litter quality was determined by measuring nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), phenol and lignin using standard methods. Soil properties including texture, lime percent, electrical conductivity (EC), bulk density, pH, nitrogen (N), phosphorus (P), potassium (K) and organic carbon (OC) were also measured by standard methods.One way ANOVA was used to compare the species in terms of litter quality and Duncan test was used to separate the means with significant difference. The relationship between litter quality and soil properties was finally determined with Pearson correlation. The highest amount of P and N were found in Centaureavirgate and the highest amount of Kwas observedin Artemisia aucheri. In addition, the highest amount of lignin was observed in Scariolaorientalis. The highest amount of P, lime, silt, clay, clay, pH, organic carbon and bulk density was in the soils (0-15cm) of Artemisia aucheri habitat.Furthermore,the highest nitrogen valuewas found in the soils of Centaureavirgata habitat. The highest amount of potassium and sand was in Scariolaorientalis habitat. At 15-30 soil depths, the highest amounts of potassium, phosphorus, clay, silt, silt clay, and pH were in Artemisia aucherihabiat`s soils.The highest carbon content, bulk density, EC were in Centaureavirgata and the highest amount of lime, gravel, and nitrogen were in the Scariolaorientalis habitat`s soils. The results showed Centaureavirgata was a species with the best litter quality, and Artemisia aucheri had the most positive impact on soil and litter quality characteristics of the studied species had good corrcration with soil chemical properties
