The most part of territory of the Republic Moldova is covered by agro-ecosystems in which the algae play a fundamental role as they are considered indicators of soil quality. Soil samples were taken from different regions of the country on which are cultivated wheat, rape, potatoes and chick-pea and were analyzed within the Scientific Research Laboratory „Algaeology”, of the State University of Moldova during 2007 – 2010. All in all, in the taken samples there were found 100 species and intraspecific varieties: Cyanophyta – 82 species, Bacillariophyta – 8, Xanthophyta – 3, Euglenophyta – 2, Chlorophyta – 5. The richest diversity was found in the soils cultivated with wheat - 42 species and intra-specific varieties.

Keywords: algae flora, agro-ecosystems, cereal crops, ecological groups, eco-bimorphs.
