Abstract

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.
