The present project aims at comprehensive research on the structure of grey-brown soil (Orthic Luvisol) built on silt in sunflower rhizosphere. Special soil samples were taken for the tests from the areas adjacent to plant roots. After a morphological analysis it was found out that in the 2-10 cm depth layer of the tested soil in sunflower rhizosphere a mixed structure prevailed - a large number of aggregates and biogenic hollows could be seen, few cracks and small fragments of higher density soil located far from the roots
