Defining sustainable agricultural practices requires an understanding of both aboveand below-ground consequences to management strategies. While alternatives to biocides are sought for the control of weeds, insects and pathogens, biocide use will continue with the goal of reducing quantities used in an integrated approach. The impact of three fungicides on plant growth, seed yield, seed nutrien...

conclusions this study showed that the collected soil from studied areas was rich of keratinophilic fungi and actinomycetes, therefore hygiene protocol should be taken to prevent the spread of pathogenic and saprophytes fungi in the environment of susceptible person. background keratinophilic fungi are a group of fungi that colonize in various keratinous substrates and degrade them to the compo...

Sewage sludge is widely used as an organic soil amendment to improve soil fertility. We investigated the effects of sewage sludge (SS) application on certain biological parameters of Eucalyptus globulus Labill. The plant was either uninoculated or inoculated with saprobe fungi (Coriolopsis rigida and Trichoderma harzianum) or arbuscular mycorrhizal (AM) fungi (Glomus deserticola and Gigaspora r...

Robinia pseudoacacia L. (black locust) is a widely planted tree species on Loess Plateau for revegetation. Due to its symbiosis forming capability with arbuscular mycorrhizal (AM) fungi, we explored the influence of arbuscular mycorrhizal fungi on plant biomass, root morphology, root tensile strength and soil aggregate stability in a pot experiment. We inoculated R. pseudoacacia with/without AM...

One of the main European agricultural problems is the decline in soil fertility due to the reduction of the natural soil harmony. When natural soil composition is altered, few cultivated plants replace spontaneous populations of numerous species. Man becomes the only regulator of a new fragile equilibrium between the simplified biocenosis elements. Agronomic techniques (fertilisation, irrigatio...

Communities of plants, biological soil crusts (BSCs), and arbuscular mycorrhizal (AM) fungi are known to influence soil stability individually, but their relative contributions, interactions, and combined effects are not well understood, particularly in arid and semiarid ecosystems. In a landscape-scale field study we quantified plant, BSC, and AM fungal communities at 216 locations along a gra...

BACKGROUND The importance of soil biota in the composition of mature plant communities is commonly acknowledged. In contrast, the role of soil biota in the early establishment of new plant communities and their relative importance for soil abiotic conditions are still poorly understood. AIMS AND METHODS The aim of this study was to understand the effects of soil origin and soil fungal communi...

In the present study, the occurrence and species diversity of insect-associated fungi in soil collected mainly from forest habitats in different regions of China were compared by using the ‘Galleria biat method’. Insect-associated fungi were defined to include known insect pathogenic fungi, opportunistic pathogens and secondary colonizers isolated from the Galleria mellonella bait insect expose...

Soil is a source of primary inoculum for Aspergillus flavus and A. parasiticus, fungi that produce highly carcinogenic aflatoxins in peanuts. Aflatoxigenic fungi commonly invade peanut seeds during maturation, and the highest concentrations of aflatoxins are found in damaged seeds. A laboratory procedure was developed in which viable peanut seeds were wounded and inoculated with field soil cont...

Soils in terrestrial ecosystems store more carbon (C) than plants and the atmosphere combined, and ecosystems’ C dynamics are strongly dependent of nitrogen (N) availability. Moreover, plant production in boreal ecosystems is often limited by low N availability, and N retention in soils is a major constraint on N recirculation to plants. Soil fungi strongly influence C and N interactions in bor...
