Abstract

BIOLOGICAL SOIL CRUSTS occur as assemblage of lichens, mosses, liverworts, and cyanobacteria. Lichens and mosses are the two important components of BIOLOGICAL SOIL CRUSTS, especially in arid and semiarid RANGELAND environments, where vascular plants vegetation is poor. Available information indicates that BIOLOGICAL SOIL CRUSTS contribute to a variety of ecological functions such as soil stabilization and vascular plants establishment, but their role in INFILTRATION is not well understood and results of reported researches have been conflicting.Current study was conducted to show possible effects of biological crusts on soil infiltaration rate and moisture condition on QARA QIR RANGELANDs, with an area of 8560 ha, in Turkmen steppe. For this, double ring, core and tensionmeter were used to determine INFILTRATION rate, moisture condition (weight and volume percentage) and matric potential, respectively. Since research was performed at one site with the same climate, topography, vascular plants, and soil texture, the difference of the study points in soil – hydrologic properties, was related to the absence or presence of cryptogamic crust. Comparing means using t- test showed a significant difference between above-mentioned factors in crusted and uncrusted soils. Crusted soil had better condition in view point of INFILTRATION and moisture. Therefore, one can conclude that presence of lichens and mosses in QARA QIR RANGELANDs is important for soil-water relations.
