Environmental Monitoring and Assessment, 2005
Soil respiration is considered to represent the overall microbial activity reflecting mineralisation of organic matter in soil. It is the most commonly used biological variable in soil studies. In long-term monitoring of forested areas, there is a need for reference values for soil microbiological variables in different forest ecosystems. In this study

Environmental Monitoring and Assessment, 2007
In this study, soil samples (0-5 cm depth) were taken from ten different roadside fields of intensive traffic regions of Van-Turkey in order to determine the effects of heavy metal pollution on enzymes and microbial activities of soils. Basal soil respiration (BSR), arylsulphatase (ASA), alkaline phosphatase (APA) and urease (UA) enzyme activities, and

Are the soil microbial biomass and basal respiration governed by the climatic regime?
Soil Biology and Biochemistry, 1990Abstract Soils in C equilibrium from various climatic regions were sampled to assess the influence of macroclimate on soil microbial biomass (C mic ) and basal respiration (CO 2 -evolution). C mic was measured using the substrate-induced respiration technique.

Abstract Monitoring soil quality by means of biological indices can be of help for the management and sustainability of soils that received sewage sludge application. The objective of this study was to evaluate the effect of long-term and continued application of sewage sludge rates on microbial biomass, basal respiration, metabolic quotient and ...

Abstract Land‐use change directly impacts soil basal respiration (Br), soil microbial attributes, and soil organic matter (SOM) composition. However, the role of soil microbial attributes and SOM composition in influencing soil Br under land‐use changes remains largely undetermined.

Basal rates of soil respiration are correlated with photosynthesis in a mixed temperate forest
Global Change Biology, 2007AbstractMany field studies have demonstrated that soil temperature explains most of the temporal variation in soil respiration (SR). However, there is increasing evidence to suggest that SR is also influenced by current, or recent, photosynthate. Accordingly, seasonal changes in SR nominally attributed to temperature may, in part, be due to seasonality

This study investigates the effects of Pb during time on the bacterial communities of forest soils using water-extractable Pb concentrations in the soil solution as predictors of Pb bioavailability. In a microcosm experiment we applied increasing concentrations of Pb(NO(3))(2) solutions (0.5, 2, 8, 32 mM) to 5 forest soils of pH6.5.

The application of parathion (PTH) in agriculture can result in its entry into the soil and threaten the soil environment. Monitoring the PTH residues and assessing toxicity on soil health are of paramount importance to the public. Herein, the dissipation of PTH and concomitant influence on microbial activities [FDA hydrolase (FDA‒H), microbial biomass
