TL;DR: An R code is developed to perform quantitative analyses of nematode assemblages using spreadsheet software and requires only an input table with taxonomic inventory data and provides output within a few seconds.

TL;DR: In this paper, the effects of wood-derived biochar on soil microbial community were investigated in a wheat crop in Tuscany (Italy), where soil samples were collected 3 and 14 months after treatments over two successive growing seasons, and analyzed for pH, total organic C (C org ), extractable C(C ext ), microbial biomass-C (C mic ), 25 specific microbial activities, mean substrate-induced respiration (mSIR) for 25 substrates, functional microbial diversity and bacterial genetic diversity.

TL;DR: In this paper, the effects of organic and mineral fertilization on soil organic carbon (SOC), total nitrogen (TN) and enzyme activities in bulk soil and particle-size fractions were investigated under a winter wheat/maize cropping system in the North China Plain.

TL;DR: In this paper, six biochars were tested on two soil-dwelling invertebrates in short-term bioassays to determine effects on survival and reproduction of collembolan adults.

TL;DR: In this paper, the authors investigated the microbial community composition and functional patterns along an elevational gradient (3100-4600m above sea level) on Mount Segrila using phospholipid fatty acids (PLFAs) and community level physiological profiles (CLPP).

TL;DR: In this article, a field experiment was carried out to investigate the effects of biochar amendment on NGHGE and GHGI emissions in a subtropical double rice cropping system managed with intermittent flooding during two rice growing seasons and drainage during a fallow season from April 2012 to April 2013.

TL;DR: Only SBER3 isolate was able to metabolize wide range of polyaromatic hydrocarbons (PAH) and other hydrocarbon used in the study i.e. anthracene, naphthalene, benzene, toluene and xylene on minimal salt basal medium (MSB) as sole source of carbon and energy.

TL;DR: An Indigenous symbiotic N2-fixing bacteria, Rhizobium leguminosarum BHURC04 (Cicer sp.) was found significantly better for nodulation, plant growth and yield of chickpea over control in a field trial and could be more effective for higher grain yield of chickspea as compare to individual or co-inoculations of R. leguminOSarum alone.

TL;DR: It was observed that native Rhizobium–Pseudomonas co-inoculation as compared to single RhizOBium inoculation increased the nodulation, growth parameters and yield of the different genotypes.

TL;DR: In this paper, the impacts of long-term application of inorganic and organic fertilizers on the activity, community composition, and abundance of denitrifying bacteria in an aquic soil of Northeast China were analyzed.

TL;DR: In this paper, the soil quality index (SQI) was evaluated with a cluster analysis and a principal components analysis to compare soil quality classes among the vegetation types, and the results indicated that soil organic matter, the MBC/TOC ratio and soil basal respiration were the most important factors reflecting the general chemical and biological properties of the soil.

TL;DR: It is shown that in these soils, high pH, salinity and nutrient conditions all had affected soil microbial activity and community structure, and although the high pH favoured bacteria, this was, however, not found for high salinity soils.

TL;DR: Application of both the bacterial strains as bio-inoculants showed significant effect on maize and wheat grain yield and on soil fertility at all different agroclimatic regions.

TL;DR: The results demonstrate that encapsulated K. oxytoca Rs-5 has more potential positive effects on cotton seedlings than free cell under salt stress and encapsulated bacterial treatment is better than free bacterial treatment in improving the cell colonization characteristics.

TL;DR: It is demonstrated that low soil P availability increases both PMB density in the rhizosphere compared to the bulk soil and the activities of PMB populations through different growth patterns.

TL;DR: Higher potential nitrification rates (PNR) were found in the combined N and P addition treatment groups than that in the other treatment groups, and the lowest PNR and pH levels were observed in the treatment with long-term application of NH4Cl plus KCl.

TL;DR: The results revealed that soil microbial communities changed during continuous cropping of cucumber, which may be both a cause and a reflection of the poor plant growth performance.

TL;DR: In this paper, the effect of the number of drying and rewetting (DRW) cycles on the distribution of respiration and how the length of the moist period influences respiration in residue-amended soil was assessed.

TL;DR: Li et al. as mentioned in this paper investigated the effects of temperature and moisture on net nitrification and N mineralization rates in BSC-dominated desert soils, and highlighted the regulatory role of BSC on N availability in the Tengger Desert, China.

TL;DR: In this paper, the effects of ammonium nitrate (AN), urea (U), and litter amendment on activities of soil microbial extracellular enzyme, soil microbial biomass C (MBC), dissolved organic C (DOC), and C mineralization in freshwater marsh were examined.

TL;DR: Based on comparative sequence analysis of almost full length 16S-rRNA coding gene fragments, Cellulosimicrobium sp.

TL;DR: It is indicated that legume species even with small differences in C-to-N ratio and lignin and cellulose contents could have varied effects on soil microbial properties and processes.

TL;DR: Interestingly, the bacterial community associated with soybean roots after glyphosate application not only demonstrated effective resilience after the disturbance but in addition, T-RF diversity also increased in comparison to the untreated control samples, suggesting that bacterial diversity was even stimulated in the rhizosphere after glyphosateApplication.

TL;DR: Data suggest that the B. megaterium M3, A. brasilense sp245, and R. terrigena TFi08 strains have the potential to be used as organic fertilizers to facilitate plant growth in sustainable and organic farming.

TL;DR: The immune response, indicated by phenoloxidase enzyme activity, is highly sensitive to environmental pollution in the preimaginal stages and thus can be used as an early warning parameter to assess the sublethal effects of heavy metal pollution.

TL;DR: The symbiotic effectiveness stability of Agrobacterium strains to nodulate soybean roots was confirmed using plant nodulation assay and the symbiotic properties assay revealed that all local rhizobial strains showed a wide spectrum of prolific nodulation and a marked increase in plant growth parameters compared to the un-inoculated control.

TL;DR: The plant species with the stronger competitive ability at low N level controls the microbial community in the rhizosphere, as revealed by the dominance of slow-growing microorganisms.

TL;DR: The efficiency of IM and mycorrhizal inoculations are reinforced as being as effective as exotic AM fungal isolates and dual species inoculation and IM show promise in the production of healthy seedlings, using several growing media.

TL;DR: Wang et al. as mentioned in this paper used gradient gel electrophoresis (DGGE) and phospholipid fatty acid (PLFA) analyses to study the effects of land-use conversion on soil microbial diversity and community structure.

TL;DR: In this article, a mutant species of Bacillus subtilis (B38) was acquired by UV irradiation and selection under high concentration of cadmium (Cd) in a previous study.
