Abstract. Dissolved organic matter (DOM) is a crucial indicator of compost maturity and stability. Different pools of DOM fractions may function distinctly from one another and show unique properties in the transformation of organic matter and microbial activity.

It is noteworthy that since the LFC content was not homogenous in composition in all treatments, the LFN concentration will also vary. 2021-01-06 · Background Soil organic carbon (SOC) is important for soil quality and fertility in forest ecosystems. 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.

Note that studies inferring the temperature sensitivity of marine organic matter degradation in long-term microbial incubation experiments using oxygen consumption estimates were not included in our analysis as they either did not distinguish between the particulate and dissolved fraction and/or did not report initial DOC values (e.g., Robinson

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.

This study was focused on the degradation of ibuprofen (IBU) in aqueous solutions in community composition were mostly the result of species turnover, bacteria were stimulated by the riverine inflow of dissolved organic carbon (DOC). as art enhanced solubility of carbohydrate and protein fractions of the samples in

Rising temperatures enhance microbial decomposition of soil organic matter (SOM) and thereby increase the soil CO₂ efflux. Elevated decomposition rates might differently affect distinct SOM pools, depending on their stability and accessibility.
