Understanding the processes that govern the turnover of soil organic matter (SOM) is central to understanding the functioning of soil systems and to predicting plant nutrient supply (Waksman & Gerretsen 1931; Schimel 1995).

Enhanced turnover of organic matter fractions by microbial stimulation during lignocellulosic waste composting

Moreover, at a size two or three fold that of the atmosphere (Le Quéré et al.

The microbial turnover of SOM begins as an enzymatic lysis of high‐molecular‐weight compounds to convert them into dissolved organic matter (measured as DOC) and proceeds through DOC mineralization to carbon dioxide (CO 2). Both products of SOM, DOC, and CO 2 were monitored in this study. Light fraction carbon may have remained elevated 7 yr later due to enhanced plant growth that continue to supply organic matter through fallen leaves and dead wood. It is noteworthy that since the LFC content was not homogenous in composition in all treatments, the LFN concentration will also vary.

Labile SOC fractions are sensitive to environmental changes, which reflect the impact of short-term internal and external management measures on the soil carbon pool. Organic mulching (OM) alters the soil environment and promotes plant growth. However, little is known about the responses of 2019-11-08 · The modification of soil organic matter (SOM) decomposition by plant carbon (C) input (priming effect) represents a critical biogeochemical process that controls soil C dynamics. However, the Spectral properties of dissolved organic matter, especially the DOC-specific absorbance, were good indicators of DON bioavailability, implying that nitrogen bound into high molecular weight organic compounds, rich in aromatic groups, was more resistant to microbial degradation than algal-derived DON. 2021-04-14 · Soil organic carbon formation remains poorly understood despite its importance for human livelihoods.

The turnover time of the microbial biomass during a steady state condition, i.e. where there is no change in the biomass size with time, can be given by t = 2.303 log (x/x-a)]/k matter inall terrestrial ecosystems (Prentice etal.,2001; Post et al., 1990).

Biologically active C and N fractions, including microbial biomass and mineralizable C and N, are important for under-standing nutrient dynamics, which can affect short-term nutri-ent immobilization during rapid microbial growth and activ- Our findings contrast the hypothesis of increased microbial N mining as a key driver behind the priming effect and rather suggest that C addition promoted the mobilization of other soil C pools that replaced lignin, chitin, and protein as microbial C sources, for instance by releasing soil compounds from mineral bonds. Understanding the processes that govern the turnover of soil organic matter (SOM) is central to understanding the functioning of soil systems and to predicting plant nutrient supply (Waksman & Gerretsen 1931; Schimel 1995).
