Sources and composition of soil organic matter fractions between and within soil aggregates. where k is the turnover factor, t is time, x is the dry weight of the microbial biomass pool size, and a is the production of new material per hour. 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).

Uncertainties remain for the relative contributions of aboveground, root, and rhizodeposition inputs to particulate (POC) and mineral-associated (MAOC) organic carbon fractions. Combining a novel framework with isotope tracer studies, we quantified POC and MAOC formation efficiencies (% of C 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.

15 - 24 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 fraction of total organic C near the soil surface under pastures (Franzluebbers and Stuedemann, 2002a). 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- Enhanced turnover of organic matter fractions by microbial stimulation during lignocellulosic waste composting Enhanced organic matter turnover was detected in lignocellulosic composting piles 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 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. In support of this conclusion, trees exposed to both elevated CO Soil organic carbon formation remains poorly understood despite its importance for human livelihoods.

The larger fungal communities in small macro-aggregates could promote soil aggregation and C sequestration. Organic fertilization increased the substrate contents in soil aggregates and enhanced soil aggregation and microbial activity in macro-aggregates, which are critical factors that facilitate C transformation and sequestration. 2021-01-01 · Enhanced turnover of organic matter fractions by microbial stimulation during lignocellulosic waste composting Bioresour.
