Environmental aspects of soil surface sealing and compaction

The paper presents some environmental impacts caused by two important factors of physical degradation of the soil, i.e., soil surface sealing/crusting phenomena and soil compaction. It can be concluded that despite numerous literature on the subject as well as the Authors' own data collected in model laboratory and field experiments, it is still difficult to judge to what extent the effects of those two processes are negative for both the soil environment and the plant growth.
