Abstract Residues of six plant species were incubated in the field and analyzed for decomposition rates, fungal, bacterial and total substrate-induced respiration (SIR), total fungal and bacterial biomass and changes in residue composition during 161 days. Plant residues included crimson clover ( Trifolium incarnatum L.), hairy vetch ( Vicia villosa

Substrate induced respiration in soils developed under four stages of succession on a colliery heap
Cereal Research Communications, 2007Substrate induced respiration as a measure of active part of the soil biomass increased in the chronosequence of spoil succession. This change observed first in the top (0–5 cm) and later in the bottom (10–15 cm) layer relating probably to the vegetation and soil fauna succession.

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.

Environmental Pollution, 2018
Efficiency and the preservation of soil functions are key requirements for sustainable remediation of contaminated soil. Microbial decomposition and conversion of substrates is a fundamental soil function. Pilot-scale EDTA-based soil washing recycled chelant generated no wastewater and removed 78% of Pb from acidic farmland soil with 860 mg kg-1 Pb and

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)).

The contributions of root and microbial respiration to the CO2 emission from the surface of gray forest and soddy-podzolic soils under meadow and forest vegetation were determined in field and laboratory experiments. In the field, a new modification of the substrate-induced respiration (SIR) method was applied.

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 ...

Changes in microbial biomass in the rhizosphere of young barley seedlings was studied. A fumigation-extraction (FE) method with measurement of ninhydrin-reactive nitrogen (NR-N) and a substrate-induced respiration (SIR) method were applied on a microscale to rhizosphere soil samples of approximately 0.1 g.
