Vegetation and soil properties of a sandy desert affected by shrub (Haloxylon aphyllum) plantation and oil mulching
Planting shrub seedlings under oil mulches has frequently been used for stabilizing mobile sands in Iran for during the last three decades. Sandy desert of Samad Abad, Sarakhs, northeast Iran, has been fixed by cultivating seedling of Haloxylon aphyllum under the oil mulches. Therefore this study wa...

| description | Planting shrub seedlings under oil mulches has frequently been used for stabilizing mobile sands in Iran for during the last three decades. Sandy desert of Samad Abad, Sarakhs, northeast Iran, has been fixed by cultivating seedling of Haloxylon aphyllum under the oil mulches. Therefore this study was designed to investigate the effects of the sand fixation project on soil and vegetation properties. Vegetation samples were taken in a randomized-systematic method from representative areas of the rehabilitated and control sites. At each site, nine transects, 50 meters length, were established. Canopy cover and density of two dominant shrub species (Astragalus squarrosus and Convolvolus hamadae) as well as the total canopy cover of their understory plants were measured, along the line transects. In each area, 220 individuals of each shrub (above mentioned) were selected and their total and living aerial foliage volumes were measured. Moreover, in each area, four soil samples were taken from 0-20 and 20-80 cm depths. The percentage of organic matter were measured in soil samples. Data analysis was done using independent T-test. According to the results of this research, application of oil mulched and Haloxylon plantation caused a significant reduction in the percentage of total canopy cover of A. squarrosus and density of A. squarrosus and C. hamadae but it increased the living aerial foliage volume of A. squarrosus and C. hamadae. |
