Investigation of phenological stages and pollutants’ type on the efficiency of vegetative buffer strips
Non-point source pollution is considered as a serious issue especially in the field of eutrophication for surface waters. Vegetative buffer strips include a specific plant being passed by flow before entering the waterways, so it causes to reduce runoff volume, deposited pesticides and other pollutants of the flow through infiltration, absorption and sediment deposition. The present study has b...
متن کاملDissolved Phosphorus Retention in Buffer Strips: Influence of Slope and Soil Type.
Phosphorus (P) contributes to eutrophication of surface waters and buffer strips may be implemented to reduce its transfer from agricultural sources to watercourses. This study was conducted to test the hypothesis that soil type and slope influence the retention of dissolved organic P and inorganic orthophosphate in agricultural runoff in 2-m-wide buffer strip soils. A solution, comprised of di...
متن کاملGeological controlling soil organic carbon and nitrogen density in a hillslope landscape, semiarid area of Golestan province, Iran
The effects of geological conditionwere assessed on density of Soil Organic Carbon (SOC) and Nitrogen (N)in a sequence of hillslope landscape, derived from different lithology i.e. loess deposit, reworked loess, marl with mixed siltstone and shale, reddish brown clay deposits and older loess in the semiarid area of northern Iran. However, other factors can influence SOC and N density such as la...
متن کاملFilter Strip Performance and Processes for Different Vegetation , Widths , and Contaminants
Filter strips are widely prescribed to reduce contaminants in surface runoff from agricultural fields. This study compared performance of different filter strip designs on several contaminants and evaluated the contributing processes. Different vegetation types and widths were investigated using simulated runoff event on large plots (3 m × 7.5 or 15 m) having fine-textured soil and a 6 to 7% sl...
متن کاملThe Effect of Zahab Plain Floodwater Spreading on Soil Organic Carbon Stock
Floodwater spreading (FWS) has an important role in floodwater control, groundwater recharge, restoration and enhancement of vegetation and desertification control. Since the flood causes the transporting of soil particles including organic materials, the floodwater spreading project can be a suitable place to sequestration of organic carbon in sediment yielded by flood. The knowledge of soil o...
