TL;DR: Drought and plant species composition were responsible for more than 90% of the variation of enzyme activities and decomposition of plant residues and soil organic matter will be slower under drought when plants are grown in mixture compared to monocultures.

TL;DR: In this paper, the response of soil micro-thropods to single and combined effects of ambient and elevated atmospheric CO2, ambient, elevated temperatures and changes in precipitation in constructed old-fields in Tennessee, USA was studied using open-top chambers.

TL;DR: In this article, an agricultural site with consistent long term (+20 years) treatments and a non-agricultural site (grassland) were investigated to determine land-use effects on soil microbial community structure and function.

TL;DR: The bio-organic fertiliser fortified with a mixed inoculation of QL-5 andQL-18 effectively decreased R. solanacearum disease incidence in both greenhouse and field conditions, but the suppressive efficacy in the field depended on the season.

TL;DR: In this article, the authors compared the differences between summertime and growing season N availability and microbial processing of N in Mediterranean-type grassland ecosystems where plant productivity is controlled by rainfall, and suggest a greater level of complexity in the mechanisms behind N cycling dynamics in California grasslands than previously thought.

TL;DR: In this paper, the effects of organic inputs (maize stover or manure) and inorganic fertilizers on soil macrofauna abundance, biomass and taxonomic diversity, water stable aggregation, whole soil and aggregate-associated organic C and N, as well as the relations between these variables were investigated.

TL;DR: In this article, it was shown that applying to the soil anaerobically digested instead of fresh manure might control the release of pathogens but increase that of inorganic nitrates.

TL;DR: The most effective treatment was double application of BIOII, which minimized the incidence of wilt disease, maximized biomass production, and altered microbial community structure.

TL;DR: In this paper, the effects of plant residue decomposition and biological aggregating agents (microbial extracellular polysaccharides and fungal hyphae) on soil aggregate stability and determined the microbial population at different stages of soil aggregate stabilization.

TL;DR: In this paper, the authors assess whether a long period of severe drought can affect the growth and activity of the microbiota of a semiarid soil, as well as the effect of organic amendments on soil resistance and resilience to this severe drought.

TL;DR: The results of the experiment clearly indicated the compatibility and synergy between G. mosseae and B. subtilis and suggested the use of this microbial consortium in A. annua for enhancing growth, biomass yield, and the content and yield of artemisinin.

TL;DR: In this paper, the authors investigated the fungal metabolic pathway of 4-HBA using high performance liquid chromatography-mass spectrometry (HPLC-MS) and gas chromatography mass spectrometer (GC-MS), which indicated the bioremediation potential of this endophytic fungus to degrade accumulated phenolic acid allelochemicals.

TL;DR: In this article, the authors applied composted beef manure to mine wastes at two sites at 45 and 269 Mg-ha −1 with and without lime and bentonite, respectively, to improve soil properties conducive to plant growth and may be necessary to stabilize lead and zinc mine wastes.

TL;DR: Differences among the assessed soil parameters indicate a trend of soil quality deterioration under the high-input management regime, which was recorded among farms with different soil types.

TL;DR: The role of earthworms in succession is understood to improve their role in soil restoration and soil management, and limiting environmental factors seem to play a more important role than inherent ecological characteristics like r/K selection.

TL;DR: The results show that total flavones, total phenolics, and total saponins released from S. canadensis accumulate in soil, and the concentrations of these secondary metabolites negatively correlated with disease severity of tomato, suggesting thatThese secondary metabolites contribute to the allelopathic effects of S.Canadensis on the soilborne pathogen P. ultimum.

TL;DR: In this paper, the authors used a litter decomposition experiment using natural litter mixtures with reciprocal transfers among three forest successional stages that differed in their tree species composition and general litter quality, and investigated the role of soil macro- and meso-invertebrates for HFA and their relative importance along a successional gradient.

TL;DR: In this article, the long-term effects of organic viticulture on soil quality were evaluated in a commercial vineyard where plots which had been organically managed for 7, 11 and 17 years (Organic17) were compared to conventionally managed plots (Conventional).

TL;DR: In this article, a long-term no-till subtropical rice soil ecosystem was studied to determine how tillage shifts microbial community structure and to detect the spatial scale at which microorganisms are the most sensitive to disturbance.

TL;DR: In this article, the authors examined the activities of fluorescein diacetate (FDA) hydrolase, dehydrogenase, β-glucosidase, de-hydrogenase and β-Glucosaminidase enzymes, the percentage of water stable aggregates (WSA) and soil organic carbon and nitrogen as soil quality parameters for grazed pasture and row-crop systems.

TL;DR: Evaluated interactions between four arbuscular mycorrhizal fungi and the beneficial fungus Trichoderma harzianum, inoculated in a greenhouse nursery, with regard to their effects on melon crop growth under conventional and integrated-system field conditions, and the biocontrol effect against Fusarium wilt found the AMF-inoculated plants were effective in controlling Fusaria wilt.

TL;DR: In this paper, a transect-based sampling of soil macrofauna using the standard Tropical Soil Biology and Fertility Institute (TSBF) method was employed in both the dry season and wet season.

TL;DR: A relevant role of Glomeromycotan fungal populations isolated from Cu-polluted environments in the alleviation of Cu toxicity that could allow their use in remediation programs for Cu- polluted soils is suggested.

TL;DR: Whether winter vegetation increases predation of Diabrotica virgifera, a key subterranean pest of maize, is evaluated and it is concluded that employing diverse methods provides the best insight into trophic relationships within subterranean systems.

TL;DR: In this article, the effects of forest vegetation type on labile soil organic matter (SOM) were studied in four subtropical forests in China, and the results indicated that hot-water-soluble method could be a suitable measure for labile SOM in sub-tropical forest soils.

TL;DR: It is found that severe, small-scale disturbances could be repaired quite rapidly and important functions, like soil stability and erosion protection, were functional after only eight months or one rainy season and full recovery from long-term disturbance seems to take longer.

TL;DR: In this paper, a study was done on soils of the Loess Plateau of China that had moss-dominated soil crusts propagated on different slopes, and the results showed that the artificially propagated moss crusts significantly increase infiltration consequently decreasing overland flow and this increase in infiltration is positively correlated to the soil coverage extent.

TL;DR: In this paper, a field study was conducted at a dryland agricultural farm during paddy crop season to assess the effect of fly ash (FA) and farmyard manure (FYM) amendments on the dynamics of inorganic-N (NH4+ and NO3−), N-mineralization and nitrification rates and paddy yields.
