Effect of pencycuron on microbial parameters of waterlogged soil
TLDR
The metabolically activated microbial population was more suppressed compared to the dormant population and the DCM amendment did not seem to have any counteractive effect on the toxicity of pencycuron on the microbial variables.Abstract:
A laboratory study was conducted to monitor the effect of pencycuron [1-(4-chlorobenzyl)-1-cyclopentyl-3-phenylurea] on microbial parameters of alluvial (AL) soil (Typic udifluvent) and coastal saline (CS) soil (Typic endoaquept) under waterlogged condition. Pencycuron at field rate (FR), 2FR and 10FR affected the microbial biomass C (MBC), soil ergosterol content and fluorescein diacetate hydrolyzing activity (FDHA) differentially. The DCM amendment did not seem to have any counteractive effect on the toxicity of pencycuron on the microbial variables. The change in microbial metabolic quotient (qCO2) and microbial respiration quotient (QR), indicated pencycuron induced disturbance at 10FR. Present study revealed that the metabolically activated microbial population was more suppressed compared to the dormant population.read more

Fluorescein diacetate as a stain of metabolically active bacteria in soil [garden soil, sandy soil, sand dune soil, mull, soil from Pinus, Picea and Fagus forest, fluorescence technique, acridine orange staining, fluorescein isothiocyanate staining, plate counts]
TL;DR: Fluorescein diacetate (FDA) was applied as a vital stain to soil bacteria in pure cultures, sterilized soil, and natural soils as discussed by the authors, and nearly 80% of the isolates were stained.

Effect of Insecticide-Tolerant and Plant Growth-Promoting Mesorhizobium on the Performance of Chickpea Grown in Insecticide Stressed Alluvial Soils
TL;DR: The present finding suggests that the mesorhizobial isolate endowed with multiple properties could be used to facilitate the productivity of chickpea under insecticidestressed soils.

Comparative toxicity of selected insecticides to pea plants and growth promotion in response to insecticide-tolerant and plant growth promoting Rhizobium leguminosarum
TL;DR: Of the various concentrations of the two insecticides, pyriproxyfen showed comparatively more severe toxicity to pea plants by decreasing plant biomass, symbiotic attributes, nutrients (nitrogen and phosphorus) uptake, seed yield and grain protein over the uninoculated control.

Microbial biomass and enzyme activities in submerged rice soil amended with municipal solid waste compost and decomposed cow manure
TL;DR: The studied parameters were higher when urea was integrated with DCM or MSWC, compared to their single applications, and changes in soil quality parameters should be monitored regularly, since heavy metals once entering into soil persist over a long period.

TL;DR: In this paper, a plant protection system consisting of 7 pesticide treatments was investigated for its side-effects on the soil microflora, and the results appeared to be significantly influenced by weather conditions.

Effect of pollutants on the ergosterol content as indicator of fungal biomass.
TL;DR: The results indicate that ergosterol can be a useful indicator for fungal biomass in polluted soils, and can be applied for monitoring bioremediation processes.

Relationships between microbial biomass and dissipation of 2,4-D and dicamba in soil
G. Voos,Peter M. Groffman +1 more
TL;DR: In this paper, a study was conducted to evaluate relationships between microbial biomass and the dissipation of 2,4-D and dicamba in soil and found that the size of the microbial biomass should be a strong predictor of the pesticide degradation capacity of a particular soil.

Microbial Degradation of Fipronil in Clay Loam Soil
TL;DR: In this article, the degradation of fipronil in non-sterile clay loam soil was mainly influenced by the soil microbes, which resulted in the formation of metabolite MB45950.
