Simulated decomposition rates were one-third lower under drought treatment, but there were no differences in microbial drought tolerance compared to simulations forced with ambient climate. This model result suggests that seasonal drought is a more important environmental filter than reduced precipitation during the wet season in our Mediterranean climate system. title = "Microbial decomposition of soil organic matter is mediated by quality and quantity of crop residues: mechanisms and thresholds", abstract = "Crop residue quality and quantity have contrasting effects on soil organic matter (SOM) decomposition, but the mechanisms explaining such priming effect (PE) are still elusive. Microbial indicators such as Escherichia coli and fecal coliforms and the concentration of ammonia/ammonium were investigated in urine samples that were stored at 60 °C and 70 °C.

N deposition can stimulate plant growth and soil carbon (C) input, enhancing soil C storage.

Information is provided on the microbial decomposition of municipal solid waste and the conditions which influence decomposition rates. 2020-03-11 Therefore, microbial decomposition of cellulose cannot occurs without nitrogenous sources. ii.

Microbial decomposition is often highest at intermediate moisture levels, when soils are dry enough that oxygen availability is not limited but not so dry that microbes have insufficient access to water (Chapin et al., 2011a). Thus, post-fire changes in microbial decomposition may depend on the degree of soil drying following the fire.

Microbial indicators such as Escherichia coli and fecal coliforms and the concentration of ammonia/ammonium were investigated in urine samples that were stored at 60 °C and 70 °C.

The amount of soil carbon considered in the 21st-century simulations determines the regional carbon sink and source strengths, regardless of the complexity of models used.

Those decomposition models are not able to capture the spatial distributions of SOC stocks and primary drivers of SOC dynamics [Todd‐Brown et al., 2013], while microbial‐based soil organic matter decomposition models have been increasingly used at both site‐ and global‐scale studies [Allison et al., 2010; He et al., 2014b; Wieder et al., 2013], although more rigorous examination of 2021-03-26 Although bacteria were important in regulating buried litter decomposition rates and the population dynamics of bacterivorous fauna, their influence on buried litter N dynamics remains less clear. The larger microbial biomass and greater contribution of a bacterivorous fauna on buried litter is consistent with the greater carbon losses and lower carbon assimilation in CT than NT agroecosystems.

2020-02-06 · Increasing the pH from ~3.5 to ~5.5 altered microbial community structure, however increases in CH4 production were non-significant. Contrary to expectations, N and P additions did not increase CO2 and CH4 production, indicating that nutrient availability was not a primary constraint in microbial decomposition of deep peat. Indole and its derivatives, including 3-methylindole and 4-chloroindole, are environmental pollutants that are present worldwide. Microbial degradation of indole and its derivatives can occur in several aerobic and anaerobic pathways; these pathways involve different known and characterized genes. In this minireview, we summarize and explain the microbial degradation of indole, indole-3-acetic Microbial decomposition of soil organic matter determined by edaphic characteristics of mangrove forests in East Asia. Sci Total Environ. 2021 Apr 1  8 Apr 2019 Bacterial enumeration demonstrated microbial burden to be higher at higher temperatures, suggesting accelerated decomposition.
