20.500.12556/RUL-135954 The effects of temporary occupation of agricultural land by gravel deposits and construction on selected soil properties Vpliv začasne zasedbe kmetijskih zemljišč z deponijo gramoza ob gradbenih posegih na lastnosti tal We addressed the condition of restored soil on alluvial plain in the south-eastern Slovenia after they have been given for the gravel deposit easement during construction. According to pre-investigation using soil probes, two soil profile pits were dug: Profile 1 on the area where excavated soils were deposited over original soils; and Profile 2 on the area where topsoil had been removed before gravel deposition and reapplied after the easement. Undisturbed and disturbed soil samples were collected and analyzed for physical and chemical properties. The results show that chemical properties were generally not the limiting factor for soil fertility. Compaction of the soil reduced hydraulic conductivity and resulted in water stagnation. The bulk density on the area where the material was deposited directly on the soil surface ranged from 1.41 to 1.77 g cm-3. The hydraulic conductivity of the saturated soil was practically impermeable at depths of 10, 20, and 30 cm, indicating compaction due to high mechanical load. At the area where topsoil was removed before deposition and restored after easement the hydraulic conductivity of the saturated soil was low to moderate. Removal of the topsoil before construction began was an appropriate action, but reclamation measures are also required. fluvisols soil degradation soil restoration soil physical properties soil chemical properties fluvisol degradacija tal obnova tal fizikalne lastnosti tal kemične lastnosti tal true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-04 15:34:32 2022-04-04 15:34:33 2026-07-29 12:25:53 0000-00-00 00:00:00 2022 0 0 9 str. no. 1 Vol. 118 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2022-01-22 0000-00-00 631.4 1854-1941 10.14720/aas.2022.118.1.2415 103353603 RAZ_Zupan_Marko_2022.pdf RAZ_Zupan_Marko_2022.pdf 1 4F5FD1F922B792E3A17F90715670EE61 fb2f358e8ac6bdf9ddaeae19ecdfce47b1818ea63636adc8ce0ed8848cd2d237 afaca53a-b41c-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155287 http://ojs.aas.bf.uni-lj.si/index.php/AAS/article/view/2415/582 1 eef68423-b41b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155286 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
