Abstract

The effect of land use type on soil functioning within an ecosystem can be assessed and monitored using SOIL QUALITY attributes. Such studies, which are carried out to create a balance between the biological production and the maintenance and improvement of land resource quality, provide a framework for land degradation control and also for identification of sustainable management. The objective of this paper was to investigate the effect of conventional management systems on SOIL QUALITY indices in Boroojen area in order to identify the most sustainable practices. Five management systems including a protected rangeland, an overgrazed rangeland, an abandoned dry land farm, an irrigated wheat farm and an alfalfa farm were selected. Organic matter (OM), phosphates activity (PA), microbial respiration (MR), total nitrogen (TN), saturated hydraulic conductivity (Ks), bulk density (Db), texture, carbonates and pH were measured in the surface soil samples of each site. PA and OM were maximum in alfalfa farm and minimum in both abandoned dry land farm and overgrazed rangeland. The highest rate of MR and TN content were obtained for alfalfa and wheat farms. The lowest potential of MR was measured in protected and also overgrazed rangeland, while the lowest amount of TN was determined in overgrazed rangeland and abandoned dry land farm. The hydraulic conductivity (Ks) was found to be more sensitive to land degradation, as compared to Db. It was highest in alfalfa farm and lowest in overgrazed rangeland. The findings of this study indicate that continuous wheat cultivation, as the most prevalent management system, decreases SOIL QUALITY. This study also shows that abandoned dry land farming is ecologically the least sustainable land use in the area. Besides, soil phosphates activity, organic matter content and hydraulic conductivity seem to be the most reliable SOIL QUALITY indices for the area
