Members of the “Ecosystems” team published in the journal “Land” the results of research on the processes of plant succession taking place on sands and their interpretation in terms of biomass growth. The study documented changes in aboveground and underground phytomass of plants and their impact on soil properties. Strict relations were also determined between the degree of stabilization of the sandy substrate and the encroachment of vegetation. Moreover, it was observed that in the initial stages of succession, terrestrial soil algae and bryophytes play an important role, as they initiate the formation of the humus level, giving rise to pedogenesis. As the plant succession progressed, changes in biomass increment and soil characteristics were found. The close relation between increased biomass and soil was confirmed in morphology and soil properties, especially in Corg, Nt, and Paval.
