Root Biomass Characteristics of Paronychia Kurdica Boiss for Using in Soil Protection in Shanjan Rangelands, East Azerbaijan, Iran

Roots of plants stable soils on slope and provide resistance against the forces that improve slope instability. In NW of Iran (East Azerbaijan Province), rangelands was Utilized with animal grazing and changed to agricultural land use; this vegetation is unsuitable vegetation on slope to stable them. We studied Paronychia kurdica Boiss to determine its root biomass characteristics. Data were collected with accidental sampling method (1*1 m) with 10-cm-diameter core in this aria. Minimum, maximum and mean root biomass of this plant is 9.37, 15.70 and 13 gr, respectively.
