“…In any case, our tests suggest that T. melanosporum mycorrhization can limit in some cases, certain potassium and magnesium quantities. On the other hand, in limy soils, it has been suggested that certain ectomycorrhizal fungi play an adaptation role by restricting plant calcium uptake (Lapeyrie, 1990); nevertheless, in our experiment, calcium uptake rates were not influenced by inoculation. If Q. ilex and Q. faginea nitrogen and phosphorus uptake averages are considered from the moment of analysis in the nursery (Domínguez et al, 2000), we found that T. melanosporum inoculation was especially important to increase seedling phosphorus uptake.…”

“…In natural ecosystems, plant species can be categorized according to their ability to grow in calcareous soils: calcicole plants are found in calcareous soils and the calcifuge plants are unable to tolerate calcareous soils (Lapeyrie 1990). The difference in the ability of plants to grow on calcareous soils could be explained by the physiology of their roots in the acquisition of nutrients (Gutschick 1993).…”

Role of arbuscular mycorrhizal symbiosis in root mineral uptake under CaCO3 stress

This study investigated the effects of increasing CaCO(3) concentrations (0, 5, 10, 20 mM) on arbuscular mycorrhizal (AM) symbiosis establishment as well as on chicory root growth and mineral nutrient uptake in a monoxenic system. Although CaCO(3) treatments significantly decreased root growth and altered the symbiosis-related development steps of the AM fungus Rhizophagus irregularis (germination, germination hypha elongation, root colonization rate, extraradical hyphal development, sporulation), the fungus was able to completely fulfill its life cycle. Even when root growth decreased more drastically in mycorrhizal roots than in non-mycorrhizal ones in the presence of high CaCO(3) levels, the AM symbiosis was found to be beneficial for root mineral uptake. Significant increases in P, N, Fe, Zn and Cu concentrations were recorded in the mycorrhizal roots. Whereas acid and alkaline phosphatase enzymatic activities remained constant in mycorrhizal roots, they were affected in non-mycorrhizal roots grown in the presence of CaCO(3) when compared with the control.

“…At the same time, the high activity of acid phosphatase, which is especially pronounced in the lower horizons, can be associated with the active secretion of this enzyme by the root systems of woody plants, and associated mycorrhizal fungi. This situation is common in conditions of available phosphorus deficiency due to high content of carbonates (Lapeyrie, 1990). A high level of absolute values of enzyme activity and its gradual decrease with depth is characteristic of all natural soils with an undisturbed profile and even Technosol, in which the upper horizon is represented by a replanted introduced RAT‐horizon.…”

Enzyme activity of soils in urban landscapes of the lower Don area, Southern Russia

Soils are the main component of the urban ecosystem and they perform environment‐forming and protective functions. The dynamics of the organic matter and enzymatic activity is an early diagnostic indicator of negative changes in urban pedogenesis. However, the features of the enzymatic activity of urban soils of the Chernozem zone are poorly studied, and the available research focuses on the upper humus‐accumulative horizons or the urbic horizons. The study aimed to reveal the regularities of the enzymatic activity distribution through 200 cm in the profile of urban soils and to show their relationship with the content of the main soil components. Urbic Technosols Molic, Ekranic Technosols, Urbic Technosols, Technic Chernozems (caChernozems of fallow and virgin areas of the Rostov Agglomeration were studied. Soil samples were taken down to a depth of 200 cm. The activity of extracellular enzymes was determined by the fluorescence method. Soil organic matter content was determined by the high‐temperature combustion method on a TOC analyzer. А number of patterns in the distribution of the enzymatic activity have been identified. Most of the Urbic Technosols were characterized by a low enzymatic activity. Factor analysis showed a negative correlation of oxidative and hydrolytic enzymes in natural soil. A positive correlation of oxidases with hydrolases was shown in urbanized horizons. We found that the longer the time of sealing, the stronger the inhibition of enzymatic activity. We conclude that enzymatic activity can be used as an indicator in biodiagnostics, biomonitoring, and bioindication of the urban soils.
