Climate induced soil deterioration and methods for mitigation

According to prognoses milder winters with more precipitation, warmer and dry summers, and extreme fluctuations in the precipitation should be expected in the Pannonian region from the 2nd decade of the 21st century. The first aim of this study was to discuss the predicted climate phenomena endangering regional soils and deploying methods of measures in the alleviation steps. Further purposes were presenting examples of soils deterioration to be typical in seasons and to confirm that tillage should be an important tool realising soil preservation solutions in the practice. Considering the predicted climate extremes most of classical beliefs are to be supervised. The effects of the rain stress e.g. washing dust and clay colloids down, surface siltation, soil settlement, extension of the existing compact layer and deteriorating crumb fraction in regional soils are demonstrated. Negative impacts of the drought stress on soils are also presented, among others soil desiccation, unutilised water below serious pan layers, crumb reduction and increased dust and crust formation. The first evidence of the investigation is that climate will more incalculable in the next decades, and for this reason applying mitigation methods is really urgent. The second evidence refers to the soil tillage which could take part in the degree of climate induced damages through soil condition modification.
