The aim of this study was to investigate the effect of the application of processed slag on steel industries on reducing wind erosion, controlling sand dunes and fine dust. For this purpose, first an area of about 7 hectares was selected in one of the Segzi plain harvesting centers and the design plan was implemented in the form of completely random blocks and as a split plot in 6 treatments with 3 replications, including control and 5 soil thickness levels. After distributing and distributing different sizes of slag in the plots, at the beginning and end of each plot, sediment traps were installed at two heights of 10 and 50 cm. To increase the accuracy of each treatment, a plot was selected and at the beginning, middle and end trays for collecting creep sediments. And a rolling mill was installed and measured simultaneously with the removal of soil moisture-trapped sediment traps with a TDR machine. The results showed that slag ability to control and trap wind sediments depends on the size of the slag particles (volume) and the length of the field covered with slag because changes in grain size charts along slag-covered plots indicate that Towards the end, the amount of precipitation is reduced and the granulation of the sediments is directed to the larger particles. The presence of porosity in the larger particles of slag justifies the possibility of retaining moisture in it. Restoration of lost vegetation can be characteristic of changes in the area covered with soil, which can be due to the presence of moisture as needed by the plant or increased fertility or both causes at the same time. Based on the results, it can be concluded that slag in large sizes can be an effective soil cover in controlling wind erosion. Economically, compared to oil mulch, although the initial costs of slag are higher, but due to higher durability (at least 10 years), no pollution in the environment, maintaining and in some cases increasing soil permeability, no degradation and easy regeneration are still affordable. It is economical and recommended. |
