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

Substrate‐Induced Respiration of a Sandy Soil Treated with Different Types of Organic Waste
Communications in Soil Science and Plant Analysis, 2010A sandy soil was amended with different types of sewage sludge (digested, dried, and composted) and pig slurry. The composted sludges displayed higher organic‐matter stability (39–45%) than only digested sludge (26–39%) or digested + dried sludge (23–32%). The microbial biomass of the dried sludge was undetectable.

© 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 ...

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.

Journal of Environmental Science and Health, Part B, 2019
After application, herbicides often reach the soil and affect non-target soil microorganisms, decreasing their population, diversity or affecting metabolic activity. Therefore, laboratory studies were performed to evaluate the effects of diuron, hexazinone and sulfometuron-methyl alone and mixed upon carbon transformation by soil microorganisms in ...

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 ...
