TL;DR: Evaluated cyanobacterial isolates from the rhizosphere of wheat gave statistically equivalent results as compared to application of with full dose of chemical fertilizers in terms of grain yields, and significant enhancement in microbial biomass carbon in the treatments was observed at mid-crop and harvest stage.

TL;DR: Soil moisture effects were more pronounced in clover than in ryegrass suggesting a dominant effect of clover in the mix, and diversity of substrate utilization and average well colour development were affected by plant species and soil moisture.

TL;DR: It seems that traps with preservative are the best choice to use in further studies concerning the epiedaphic fauna of the olive grove, as they reached the highest accumulation of species for a small number of pitfalls when compared with the other pitfalls studied.

TL;DR: It is shown that besides plant establishment, successful colonization of post-mining sites by soil fauna seems to be critical for soil development as the substantial part of newly formed soils consisted of soil macrofauna faeces.

TL;DR: It is suggested that wider use of established culture techniques allied to ecological requirements and behaviour of species will increase the consistency and validity of sub-lethal earthworm toxicity tests.

TL;DR: The VFG compost had a larger overall positive effect on the three soil faunal groups than cattle slurry, and adding organic amendments resulted in increased numbers of micro-arthropods, springtails as well as mites.

TL;DR: In this paper, the use of easily biodegradable chelating agents in the assisted phytoextraction process and to evaluate their effect on soil and Mirabilis jalapa plant associated bacteria was evaluated.

TL;DR: The vermicomposting process did not result in an increased availability of nutrients or potentially toxic elements, the only exception being Zn as discussed by the authors, while green waste compost feedstock showed poor growth.

TL;DR: Investigation of the impact of 10 years of experimental summer drought and increased summer rainfall manipulations on the soil fauna of a calcareous grassland finds that the responses of root herbivores to an increased incidence of summer droughts are likely to vary, depending on their feeding strategy and life history.

TL;DR: There was a positive correlation between earthworm and tree species diversity indicating the importance of diverse food qualities for the decomposer fauna at the local scale especially in springtime.

TL;DR: The study shows the possibility of additional metabolic interactions between bacteria and plants in contaminated environment on level of their intermediates and their transformation and gives more detailed information about abilities of biological systems to metabolise original xenobiotics and also their intermediate and products.

TL;DR: In this article, an engineered in situ biostimulation of a hydrocarbon-polluted subsoil of an old metal-working plant was presented, based on the injection of hydrogen peroxide, an oleophilic fertilizer, and a surfactant.

TL;DR: It was found that the midgut fluid taken form anterior part of the digestive tract could suppress formation of colonies of bacteria, inhibit the germination of spores and reduce the radial growth rate of some fungal colonies.

TL;DR: Results show that vermicompost could be an environmentally friendly substitute for peat in potting media with no detrimental effects on seedling performance and fruit quality.

TL;DR: In this article, the authors describe earthworm communities along an elevation gradient of eight forest types in Northeastern Puerto Rico, and determine whether their abundance, biomass and or diversity is related to climatic, soil physical/chemical and/or biotic characteristics.

TL;DR: In this article, the bicarbonate alkalinity required to maintain pH above 6.5 is a function of the electron donor: 800mg/L of bicarlarithm is sufficient to achieve about 1.2mM TCE dechlorination with glucose, 1.7mM with lactate, and a much higher 3.3mM mM with formate.

TL;DR: The role of earthworms in mineral weathering was investigated in this article, where anorthite, biotite, olivine, smectite and kaolinite were mixed with a sterilized manure substrate.

TL;DR: The results did not support the hypothesis that diversity should decrease in response to habitat disturbance, and contradicted the intermediate disturbance hypothesis; species richness was not the highest in the moderately disturbed suburban area.

TL;DR: Air-dried soils can be used as part of soil quality analysis to estimate these biochemical properties in summer time in the semiarid region of South-East Spain, because they have not suffered severe affections, and MBC could also be determined using air-d dried soil in the driest zones during all year.

TL;DR: A community including more sensitive species Lumbricus terrestris and Aporrectodea longa, or the most sensitive species Allolobophora chlorotica and Lumbicus castaneus, indicates more favourable conditions of habitat.

TL;DR: This study indicates that the non-random selection observed in the two lawns is because there is an interaction between species close to the same ecological category.

TL;DR: In this paper, the effects of high cadmium and nickel soil concentrations on selected physiological parameters of Arundo donax L. donax plants were investigated in a 2-year pot experiment and the pots were irrigated with aqueous solutions of Cd and Ni in concentrations of 5, 50 and 100ppm against the control (tap water).

TL;DR: In this article, the authors used the HM-1D chemical transport and speciation model and an one-dimensional analytical solution model to simulate the removal of arsenate and arsenite by ZVI columns.

TL;DR: In this article, the effect of thermophilic pre-composting followed by vermicomposting on compost characteristics compared with thermophilically pre-compositioning and windrow composting was determined.

TL;DR: The susceptibility of coelomocyte membranes to Cd-evoked toxicosis is not correlated with C d-induced MT2 expression levels, and Transcriptome measurements indicated that basal MT gene expression levels were higher in E. fetida than in L. terrestris, but Cd's up-regulation was approximately similar in samples from the two species.

TL;DR: Insight is provided into the response of bacterial community following environmental perturbations caused by nickel-mining activities and revegetation efforts, and no significant differences in species richness were observed between the different environmental samples.

TL;DR: This work focuses on protease activity of the species A. caliginosa and L. rubellus, by characterizing activity parameters (time course, pH optimum, temperature sensitivity) and by comparing enzyme patterns of untreated and stimulated CF samples separated by PAGE.

TL;DR: Results suggest that seed herbivory and seed transport are important mechanisms by which earthworms can selectively alter the diversity of grassland ecosystems.

TL;DR: In this paper, the SS-SBR (Soil Slurry - Sequencing Batch Reactor) process for the remediation of soils contaminated by several organic pollutants has been evaluated.

TL;DR: In this article, the role of abiotic (texture, calcium carbonates or iron) and biotic parameters (earthworm and enchytraeid activities) on the initial phases of soil aggregation was examined.
