Influence of Windbreak-trees on the Soil'sPhysical and Chemical properties, Humidity and Erosion in Arid Regions (Case Study: Semi-arid Lands of Aaran and Bidgol). E.E.R. . 2012; 2 (1) :53-62
Abstract:   (13428 Views)

When aerial parts of the plants capable of storing absorbing mineral salts in their leaves fall, these dissolved materials are transferred to the soil surface, changing its physical and chemical properties. In this study, we have investigated the influence of the Haloxylon tree on the physical and chemical properties, and also humidity of the soil using two, 300 m long transects one canopy of the trees (1.5 m distance from the tree trunk) and another one used as the reference located at a distance five times as long as the tree’s height (almost 50 m away from the tree trunk). Thirty points were selected on each transect, and samples were taken from depths of 0-10, 10-20, and 20-30 cm of the soil. Measurements were taken with respect to Ca+, Mg+, K+, Na+, pH, EC, biomass and volume humidity.
