Sažetak
The need to reduce the environmental impact of agricultural activities and to control soil structure degradation is one of the main aims of conservation land management. We show here the experiments and measurements we conduct within the SEDCRO project to help the scientists, farmers and policy makers in the understanding of the soil and hydrologic processes. The main factors that determine soil losses and runoff was assessed: slope, soil management, vegetation cover, organic matter, infiltration, soil moisture, soil water repellency, and structural stability. Project outcome reveal that several strategies should have to been developed to reduce the most important degradation problem - soil erosion: 1) terracing on steep slopes, 2) use of cover crops, 3) mulching and 4) no-tillage. Inappropriate practices (wheeling, agrochemicals, tillage) accelerates soil compaction, runoff and soil erosion in Croatian pedosphere. This also increase risk of surface water pollution. Complex of agricultural, social, economic and environmental reasons are generally the driving force for unsustainable soil management practices in Croatian agricultural land. SEDCRO project fill the gaps in several missing things: 1) a lack of research of proportion of soil erosion in Croatia ; 2) lack of knowledge of driving forces of erosion - like aggregate stability, effect of slope, and physical and chemical properties which control the aggregate breakdown ; in contrast to: a) different soil types b) land use, c) topography and d) rainfall intensity. The mechanisms, processes, rates and control of soil erosion have been scientifically studied for more than four years to convey new findings and discuss new challenges. In Croatia, such research trough SEDRCO project provides more than 19 scientific papers, 1 book and 1 book chapter, while from 3 PhD candidates that work on project one become doctor and other two will be in 2023. Outcome of the SEDCRO project will help to improve management of agricultural soils under more pronounced every-day climatic extremes in Croatian environment. Research of soil erosion and degradation on Croatian provide deep insight for understanding the processes of soil degradation and extent of degradation damage for future change of legal policy. Present subject of research helps to discover most endanger soils and unsustainable land use practices, which help to conserve soil and water for future generations.
