TL;DR: In this article, a comprehensive analysis of invertebrate activities shows that they may be the best possible indicators of soil quality, and they should also be considered as a resource that needs to be properly managed to enhance ecosystem services provided by agro-ecosystems.

TL;DR: The interactions between earthworms and microorganisms can produce significant quantities of plant growth hormones and humic acids which act as plant regulators, and the differences in effects between the most effective dosage rate of humic acid from food waste, a phytohormone (IAA), and a commercial source of humIC acid are compared.

TL;DR: The different values of soil fauna are identified and how they participe to the provisioning of key ecosystem services are discussed, showing the enormous gap between their recognised usefulness and their consideration in protection policies is discussed.

TL;DR: In this paper, the effect of a new pesticide, acetamiprid, applied at normal field concentration (0.5 ǫ kg−1 dried soil) and at high concentration (5 and 50ǫkg−1 dry soil), on soil enzyme activities and soil respiration in upland soil was studied.

TL;DR: The modification of the composition and activity of soil biota under Mucuna might partly explain the potential of Mucunas for soil restoration.

TL;DR: The data from the present study suggests that, AM symbiosis helps in increments of enzymatic and non-enzymatic antioxidant productions which in turn help AM plants to enhance drought tolerance.

TL;DR: Results suggest that the enzyme activities measured originated mostly from microorganisms and that C hwe is an important C source for soil microorganisms.

TL;DR: In this article, the authors used chloroform fumigation incubation (CFI) as well as extraction (CFE) techniques and the substrate induced respiration (SIR) technique while C and N mineralization were measured.

TL;DR: This study studied the snail fauna of four primeval forests of Central Slovakia and focused on the influence of forest type and coarse woody debris (CWD) on species assemblages.

TL;DR: In vivo studies conducted in the presence of single bacterial strains showed that the type of ingested bacteria conditioned the development of the different bacterial-feeding Cephalobidae nematodes species tested and that the effect of bacteria differed between nematode species.

TL;DR: Surprisingly, the most representative extracted cells were obtained from the soil exhibiting the lowest efficiency of cell recovery, demonstrating that quantitative and qualitative cell recovery using Nycodenz density gradient centrifugation are not necessarily related and could be differentially biased according to soil type.

TL;DR: It can be concluded that RP fertilization instead SP could allow obtaining acceptable tall fescue and wheatgrass yield enhancing mycorrhizal potential of soils and indigenous colonization of plants and thus maximizing the use of fertilizer.

TL;DR: In this article, soil macroinvertebrates from three replicate sites of cultivated fields, grass-dominated fields, loblolly pine stands, and remnant hardwood stands were sampled for a period of 2 years, with the objective of examining soil invertebrate community composition.

TL;DR: These methods are proposed to use in all studies collecting data on soil organism communities for legal purposes such as long-term monitoring or soil quality assessment, as well as in special cases when working in different climatic regions like the tropics.

TL;DR: In this paper, the authors used radial compression strength (RCS) to measure wood decomposition in boreal mineral soils and found that RCS was a better indicator of wood strength change in southern pine (Pinus spp.) and aspen ( Populus tremuloides Michx.) than surface hardness or longitudinal shear.

TL;DR: Although earthworms produced an increase in microbial biomass and activity in young modules, finally a decrease in older modules was recorded and the decrease in available carbon did not seem to affect the relationships established between earthworms and microflora.

TL;DR: The weak influence of rainfall on spatial variations of most observed mycobiotic characteristics indicated that microenvironmental factors influenced the development of studied communities more essentially than macroenvironmental (climatic) factors.

TL;DR: In this article, the authors examined differences in biodiversity of terrestrial isopods along a gradient of disturbance from two undisturbed primary tropical rainforest sites, to a logged site, a mixed native fruit orchard and a commercial oil palm plantation, in Sabah, East Malaysia.

TL;DR: In this article, the authors use the state factor equation to identify conditions for small or large engineering effects on soil processes, assess engineer impacts on multiple soil processes and compare effects of different engineers on a given soil process.

TL;DR: The results showed that litter quality, but not litter diversity was the factor which affected the three animal groups under study, and maturity index of nematode communities was found to be a good index to differentiate between litters of different quality.

TL;DR: In this paper, the spatial variability of the activity of three hydrolytic enzymes, i.e., urease activity, alkaline phosphatase activity and arylsulfatase activation, in pasture topsoils using geostatistics was assessed.

TL;DR: Although earthworm diversity varied significantly, the effect of seasonal variation was unclear, and on a seasonal time scale the C-score was lower than expected, showing that earthworm communities exhibit a random pattern of organization.

TL;DR: In this article, the authors investigated the performance of three species of the genus Enchytraeus (E. albidus, E. crypticus, and E. luxuriosus) using soil types covering a wide range of European and North American soil properties.

TL;DR: In this paper, the effects of soil temperatures of 5, 10 and 15°C on the decomposition of Scots pine needles were assessed in a 1-year (360 days) growth chamber experiment, and it seems that increasing soil temperatures may result in slightly higher rates of needle litter mass loss and consequent nitrogen release in northern peat than in southern peat.

TL;DR: In this paper, the authors investigated the importance of two ant species Lasius niger and Lasius flavus in a post-mining landscape near the town of Sokolov in northwest Czechia where both species are common Chemical and microbiological parameters (respiration, cellulose decomposition and direct counts of bacteria) were investigated in both ant species in two different habitats: a tertiary clay heap after brown coal mining with a weakly developed organic layer and semi natural meadows with well developed organic horizons.

TL;DR: A field experiment was conducted in southern Burkina Faso (West Africa) to investigate the contribution of soil fauna to nutrient availability and crop performance after application of different organic materials with contrasting qualities.

TL;DR: It is concluded that the reduction of collembolan and pauropod densities in high-input management systems is largely explained by the mechanical and chemical perturbations produced by conventional agricultural management practices and by particular abiotic soil conditions present in the intensively managed sites that are unfavourable for these organisms.

TL;DR: The aim of this research was to find further arguments advocating the idea of vermicomposting in household and school conditions by feeding Eisenia fetida biomass to aquarium fish.

TL;DR: Organic matter breakdown measured as mass loss of leaf litter in TMEs over time revealed that the two tested agrochemicals can have an impact on decomposition at field relevant concentrations.

TL;DR: The results show that the effect of the Bt-toxin producing maize on the collembolan is species specific.
