Determination of the soil microbial biomass carbon using the method of substrate-induced respiration
Eurasian Soil Science, 2011Specific features of determining the carbon content in the soil microbial biomass using the method of substrate-induced respiration (MBSIR) were studied as related to the conditions of the incubation (the glucose concentration and temperature) and pre-incubation (the duration and temperature) of the soil samples collected in the summer (tundra gley and

Nutrient enrichment may alter patterns of heterotrophic microbial activity (HMA) in wetland soils and influence organic matter decomposition dynamics. The response of the heterotrophic microbial community to C substrates (alcohols, amides, amino acids, aromatics, plant residues, and polysaccharides) was measured as CO

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

In studying the basal respiration, microbial biomass (substrate-induced respiration, SIR), and metabolic quotient (qCO2) in western red cedar (Thuja plicata Donn ex D. Don)-western hemlock [(Tsuga heterophylla Raf.) Sarg.] ecosystems (old-growth forests, 3- and 10-year-old plantations) on northern Vancouver Island, British Columbia, Canada, we ...

The effect of liming on microbial biomass C and respiration activity was studied in four liming experiments on young pine plantations. One of the experimental sites had been limed and planted 12 years before, two 5 years before, and one a year before soil sampling. The youngest experimental site was also treated with ash fertilizer.

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.

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.

Abstract Heat loss and respiration following amendment with glucose were recorded for soils contaminated with heavy metals and organic pesticides over a period up to 28 days. For this purpose, measuring ampoules were adapted to enable measurement of heat loss and CO 2 evolution on the same soil sample and at the same time.
