Sažetak
Tillage-induced soil compaction has often occurred in the Pannonian region. This form of compaction occurs on arable lands both in Hungary (1.82 million ha) and in Croatia (0.97 million ha) having negative impacts on crop production. In this study the tillage-induced compaction is discussed as an indicator of climate stress on arable fields. The research is based on soil condition monitoring and measuring that was started 32 years ago and on short and long-term experiments assessing the compaction impacts on the crops. The survey comprised 1870 monitoring places and 38 experimental plots. The following points were chosen for monitoring: 1. Root zone state (to a depth of 0-50 cm). 2. Occurrence of compacted layer (indicating the risk). 3. Extension of the compacted layer (indicating the degree of damage). 4. Long term effects of tillage (deterioration or improvement). 5. Tillage-induced drought and water-logging damage impacts on yield loss. The formation and location of compaction provided information concerning the depth, the method and the type of tillage applied, along with the expected risk for crop production under extreme climate conditions. The main objectives of the study are: 1. Occurrence and the extent of tillage-pan compaction in soils. 2. Consequences on water management in each of the years covered by the experiments. 3. Soil quality consequences. 4. Alleviation of pan-compaction by mechanical and biological methods. Long-term assessing has convincingly proven a correlation between tillage-pan compaction and the degree of climate stress. In view of the findings trends in soil tillage can be grouped into the following categories: climate damage mitigating and climate-stress increasing ones.
