Along the whole history, the human civilizations were depended mainly on the soil fertility and further on the ecosystem well function and its appropriate characteristics. These functions (as natural processes occurring in ecosystems) depend on its structure (on biotic and abiotic constituents respectively) and provide ecosystem services. The paper emphasized the way that one of the ecosystem services, essential to our health and well being, as the пїЅregulation of the nutrients and their uptake? arises from the i...

The objective of the paper was to emphasize the influence of the biological activity on the structural improvement of the compacted clayey pedogenetic horizons of two Chromic Luvisols, by the organic matter bioturbation. The researches were performed on two Chromic Luvisols from Romanian Plain, where the mean annual temperature is 10.5oC and the mean annual precipitation is 548 mm. The analytical data showed that clay content increased from the top layer of both soil profiles (28.9% in P1, and 29.8% in P2), to Bt ...
