TL;DR: The EcoFINDERS (FP7) project sampled 76 sites across 11 European countries, covering five biogeographical zones (Alpine, Atlantic, Boreal, Continental and Mediterranean) and three land-uses (arable, grass, forestry) to assess the range in biodiversity and ecosystem function across the sites, fourteen biological methods were applied as proxy indicators for these functions.

TL;DR: Results indicate that inorganic fertilizer plus manure increased microbial size and diversity and changed microbial composition in black soil in northeast China.

TL;DR: This review provides information about the traits and mechanisms possessed by certain Cd resistant rhizobacteria that ameliorate Cd stress to plants, and provides several examples of their use in Cd polluted agricultural soils.

TL;DR: In this paper, community-level physiological profiles (CLPP) were analyzed with ECO-plates in Dutch and European soil samples and the results showed consistent patterns in CLPP and soil habitat characteristics, as brought about by environmental disturbances, land management and soil texture.

TL;DR: Soil from the reconstructed sites showed a significantly lower microbial diversity and biomass, and lower activity of the dehydrogenase and β-glucosidase enzymes when compared to undisturbed soils.

TL;DR: In this paper, the effects of increasing N fertilization on soil CO 2 emissions and microbial biomass in a wheat rhizosphere were investigated in a 56-day incubation experiment.

TL;DR: Both B. mycoides B38 V and B. cepacia 89 showed remarkable antifungal activity in addition to other PGP characteristics, representing potential inoculants and biocontrol agents.

TL;DR: In this paper, the authors collected, harmonized, collated, modelled, and depicted on a soil biodiversity map using multiple regressions relating relatively low density earthworm community data to soil characteristics, land use, vegetation and climate factors with a greater spatial resolution.

TL;DR: In this article, a 5-year field experiment was conducted in Northern France using a combination of three factors: i) no-till (NT) vs. conventional tillage (CT); ii) with or without winter cover crops (bare fallow; cover crops with a low prevalence of legumes; cover crop with a high prevalence of legsumes); and iii) without N fertilization.

TL;DR: In this article, the effect of biochar on soil and substrate physicochemical properties, plant growth, disease susceptibility and rhizosphere microbiology in two contrasting cropping systems, i.e., lettuce grown in field soil and strawberry grown in white peat, was studied.

TL;DR: In this article, a field manipulation experiment was established to investigate the responses of soil nematode communities to water and nitrogen (N) additions in an old-field grassland ecosystem.

TL;DR: In this article, the authors examined soil chemical and biological properties to assess the short-term impacts of wildfire and prescribed fires on soil functioning in semi-arid regions of Texas.

TL;DR: Avocado trees and their rhizosphere soils harbor halotolerant IAA- and ACCD-producing bacteria with the potential to mitigate the salt stress effects on plants, and further studies are necessary to validate the effects of selected bacterial consortia on avocado growth and yields under saline conditions.

TL;DR: In this article, the authors evaluated the effect of the addition of poultry litter and biochar obtained from this material in doses of 2.25 and 5.00 t, respectively, on soil enzymatic activity, soil ecotoxicity and grass crop yield.

TL;DR: Wang et al. as discussed by the authors examined the effects of different thinning intensities (low-intensity thinning treatment with 30% of the trees removed; high-intensity thinnings treatment with 70% of trees removed, and control treatment without tree removal).

TL;DR: A European "transect" was established to assess soil microbial activity, using the MicroResp™ method, as part of a larger project looking at soil biodiversity and function across Europe as mentioned in this paper.

TL;DR: How both initial soil conditions (pH) and litter composition (C/N ratio) independently affects fungal and bacterial growth during decomposition is highlighted.

TL;DR: In this paper, the effects of N addition on soil microbial communities were investigated in an alpine meadow ecosystem near the timberline zone in the eastern region of the Qinghai-Tibet Plateau.

TL;DR: Inoculation of PGP microbes along with metabolites is showing great promise, proving to be more effective with multiple roles and hence showing the way for the development of future bioformulations as discussed by the authors.

TL;DR: In this paper, a greenhouse study on intensive agricultural soils of Southern Italy was done, where the following amendments, as soil treatment, were used: a municipal compost (MC), with C:N 133, and an on-farm compost (OF), with c:N 171, applied at the rate of 85 and 60 Mg DM−ha−1, respectively.

TL;DR: In this paper, the authors integrate metabarcoding of bacteria and fungi and soil physical measurements at 60 locations on a 15 × 15 m grid in an agricultural field to characterize the spatial variation of microbial richness and diversity, and identify the soil physical parameters that are most strongly correlated with them.

TL;DR: In this article, the differences of collembolan taxonomic and functional diversity across an European transect with sites comprising different land use types (forests, grasslands and arable lands) and characteristics in terms of habitat conditions and soil properties.
