The paper emphasizes the ecological restoration (renaturation) of the natural conditions of a saline soil, which was previously under long term melioration. The soil is a Salinic Pelic Alluvic Sodosol with relict gleization, covering an Alkali soil (according to SRTS-2012). The site is located in Moldova Tableland, where Tma is 584.6?C and Pma is 9.5 mm. The depth of the groundwater table is about 1.80 m, with frequent seasonal fluctuations and weak-moderate mineralization. The soil had a polyphasic evolution, bot...

The paper emphasizes the deep influence of soil biota on pedobioplasma illuviation and on the evolution of illuvial coatings formed in soils with Fe-humic-clayey pedobioplasma. In the studied soils, two main types of pedofeatures were noticed, which pointed out that soil biota initiated and controlled the important pedogenetic processes: coprolites (pedofeatures generated by biological activity), as well as illuvial coating (textural pedofeatures generated by illuviation). Two types of coprolites were dominant: a)...
