Structure degradation is a process of the greatest practical interest, closely associated with the effects of agriculture in general, and intensive agriculture. In this context structural degradation occurs immediately after soil cultivation, the structure is subjected to the opposite processes: formation of blocks and dispersion. Another direct cause of structure degradation is soil compaction as a result of excessive traffi c, especially on wet soil. Structure degradation in the morphological aspect leads to processes of forming of structural elements of different shapes and sizes but without agronomic value, with insuffi cient porosity and poor hidrostability.
