A critical component of assessing the impacts of climate change on watershed ecosystems involves understanding the role that dissolved organic matter (DOM) plays in driving whole ecosystem metabolism. The hyporheic zone—a biogeochemical control point where ground water and river water mix—is characterized by high DOM turnover and microbial activity and is responsible for a large fraction

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.

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). Depending on their turnover rates in soil, three conceptual C fractions can be distinguished: active-labile and active-intermediate fractions—that may remain in soil for years or decades—and passive or refractory OM remain-ing in soil from centuries to millennia. 2021-03-12 · Functional soil organic matter fractions in response to long-term fertilizer management in a double-cropping paddy field of southern China 2018-01-01 · Micro-scale ecology regulate s particulate organic matter turnover in model marine 2! microbial communities 3! ! 4!

Non-additive interactive effects positively correlated with microbial release of extracellular enzymes involved in breakdown of organic N (R2 = 0.66; P = 0.006) in the rhizosphere, indicating that exudation stimulated microbial activity and accelerated the rate of soil organic matter (SOM) turnover.

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.

SENWO Department of Biological and Environmental Sciences, Alabama A&M University, Normal, Alabama 35762 USA Se hela listan på frontiersin.org 2021-01-18 · Carbon turnover in aquatic environments is dependent on biochemical properties of organic matter (OM) and its degradability by the surrounding microbial community. Non-additive interactive effects The latter is equivalent to microbial turnover at steady state conditions (i.e., when microbial biomass remains constant in the short term, as expected in a 24 hr measurement period, and as shown by Zheng et al.

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.
