Urban sprawl and land abandonment are the major threats to agricultural areas, as highlighted the European Environment Agency. Bucharest metropolitan area is a proposed metropolitan area project, aiming to reach 2700 km2 in an intermediate stage. This area would include Bucharest City and other 62 surrounding LAUs from Ilfov, C?l?ra?i and Giurgiu Counties. The paper aims to assess the dynamics of soil sealing and soil landscape patterns and to evaluate soil productivity lost due to the urban sprawl within the Buch...

Soil organic matter is fundamental for the long-term sustainability of agro-ecosystems. An experiment was conducted on the experimental plot aiming to determine if organic matter represented by mulches with wool wastes and wood chips could induce changes in soil microbial community composition and activity and effects on improvement of soil suppressiveness to plant pathogens from the genus Fusarium. The soil was Technosol and the organic culture of edible roses was planted in 2015. In the summer of 2016 the soil w...

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 ...
