Sažetak
The biggest change occurring in the area of the highway Zagreb – Split is the degradation of the natural soil, especially its physical properties. The main objectives of this study were: (1) determine the physical properties of the soil in the area impact the highway (damaged soil) and outside these area (natural soil), and (2) determine the level, type and current processes of soil degradation. The research was conducted in 2006 on the section of the highway Zagreb - Split, from Gospić to Sveti Rok. Each of the 20 representative sites is divided into two sub sites: damaged soil and origin/natural soil to determine the condition and quality of the soil before and after the highway construction. The surface layer (0-10 cm) of damaged soils generally was less porous, smaller soil capacity for water and air, higher bulk density of soil, strong compacted, with more clay and unstable to a little stable macroaggregates. Excavation of topsoil, filling, and subsequently spreading new layers of soil in the lower horizons of the damaged soil contributed to the deterioration of its water and air conditions, poor infiltration, and difficulty in growing the plants. The results of the soil analysis as well as the state determinate in the field, indicating that the degree of soil degradation in the area of highway was extremely high. It is necessary to make repairs a unfavorable soil properties by agro ameliorative measures considering the plant requirements. Also, it is important to plan the full protection of the soil.
