© SGEM2019 All Rights Reserved. In a laboratory model experiment, the effect of native pyrochars and modified pyrochars, from which labile organic matter were extracted, on substrate-induced respiration (SIR) was evaluated. Native samples of pyrochars were obtained from the remnants of linden wood at low-temperature (250°C), medium-temperature (450°C ...

Substrate-induced respiration measured in situ in a C3-plant ecosystem using additions of C4-sucrose
Soil Biology and Biochemistry, 1996We added sucrose derived from sugar cane, a tropical C4-plant, to the soil of a temperate C3-forest plant system. The combined measurement of CO2 respiration rate and 13C natural abundance of CO2 enabled a distinction to be made between C3- and C4-respiration, which offered new possibilities to analyze basal respiration and substrate-induced ...

Abstract An incubation experiment was performed with two soils and five pesticide treatments (benomyl, isoproturon, simazine, dinoterb and chloroform). Microbial biomass C and N was estimated by fumigation-extraction (FE). Two modifications of the substrate-induced respiration (SIR) method were used: (1) a continuous flushing system and (2) a static ...

The substrate-induced respiration (SIR) method was modified and adapted to measure fungal, bacterial and total microbial contributions to glucose-induced respiration and the potentially active microbial biomass on decaying plant residues of differing composition.

Sammary-The microbial biomass of seven arctic tundra soils was measured using both the chloroform fumigation-extraction procedure (biomass-C and -N) and the substrate-induced respiration method (biomass-C only) to test the suitability of these two methods for organic and mineral arctic soils.

The content of microbial biomass (MB) was determined in samples of gray forest, chestnut, and tundra soils with different physicochemical properties (0.4-22.7% Corg; 8.4-26.8% silt particles; pH 4.3-8.4) by the methods of substrate-induced respiration (MB(SIR)) and direct microscopy (MB(M)).

Abstract Multiple substrate-induced respiration is a method for characterising and assessing the functional diversity of soil microbiota. In this procedure, an array of simple organic substrates is added to soil samples, and the resulting multiple respiration values are used to give a functional description of the microbial community.

Abstract Decomposition of soil organic matter (SOM) is regulated by microbial activity, which strongly depends on the availability of carbon (C) and nitrogen (N). Yet, the special role of N on soil organic carbon (SOC) mineralization is still under discussion.

Abstract The soil microbial biomass (SMB) is responsible for many of the cycles and transformations of nutrients in soils. Three methods of measuring and describing this pool in soil are: (1) chloroform fumigation–extraction (CFE), (2) substrate-induced respiration, and (3) total extractable phospholipid fatty acids (PLFA).
