Estimating crop residue decomposition coefficients using substrate-induced respiration
Soil Biology and Biochemistry, 1997Abstract Modeling of crop residue decomposition for nutrient cycling and effectiveness of residues to control soil erosion requires information on crop-specific decomposition coefficients (k). Respiration of decomposing residues reflects the activity of the microbial community and should give an indication of the residue decomposition rate.

Substrate induced respiration in soil amended with different amino acid isomers
Applied Soil Ecology, 1994Abstract The substrate induced respiration (SIR) by the soil microbial community was determined using glucose, l -alanine, d -alanine, l -glutamine and d -glutamine as the substrate in order to compare the utilization of l - and d -isomers of alanine and glutamine by the microbial community in a podzolic soil.

Soil respiration measurements are an established method to test the abundance, activity and vitality of the soil microorganisms. However, abnormal progressions of soil respiration curves impede a clear interpretation of the data. The aim of this study was to investigate the changes in the microbial structure during the formation of phenomena like ...

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

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.

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.

Waste Management and Research, 2014
The municipal solid waste incineration bottom ash is being increasingly used to construct landfill covers in Sweden. In post-closure, owing to increased cover infiltration, the percolating water can add external organic matter to bottom ash. The addition and subsequent degradation of this external organic matter can affect metal mobility through ...

© 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 ...
