The impacts of surface mulch-cover and soil preserving tillage on the renewal of the top layer

Global climate change, in particular, draws attention to the state and quality of agricultural soils. The relationship between soil quality factors that can be affected by tillage and climate effects have been studied in parallel in Croatia and in Hungary in long term tillage experiments and by field monitoring. The scientists focused on factors such as the looseness of the soil, the optimum depth of the loosened layer, the depth at which a compact layer is formed in the soil and the extent of the compact layer, aggregation, soil moisture, surface cover, organic materials and carbon balance as well as earthworm activity. Findings of the research point to a relationship between soil quality improvement and climate stress mitigation. Changing tillage practices – adopting shallow stubble tillage leaving mulch on the soil surface, minimising ploughing or carrying out preparation promptly at ploughing in the summer, increasingly extensive application of loosening techniques and tillage with cultivators, secondary tillage after ploughing in the autumn and radical reduction of disturbing the soil as well as minimising traffic-induced soil damage in the spring – is growing increasingly important in the Pannonian region.
