Of the many elements required for microbial decomposition, carbon and nitrogen are the most important and the most commonly limiting. Carbon is both an energy source (note the root in our word for high-energy food: carbohydrate), and the basic building block making up about 50% of the mass of microbial cells. Nitrogen is a crucial compo- Crop residue quality and quantity have contrasting effects on soil organic matter (SOM) decomposition, but the mechanisms explaining such priming effect (PE) are still elusive. To reveal the role of residue quality and quantity in SOM priming, we applied two rates (5.4–10.8 g kg−1) of 13C-labeled wheat residues (separately: leaves, stems, roots) to soil and incubated for 120 days.

Loss of dry weight is calculated. The procedure is repeated annually. In ecosystems, microbial decomposition converts detritus into CO 2 and releases nutrients for plant growth. While much is understood about how changes in abiotic conditions (2, 3) and substrate quality affect decomposition rates, the role of microbial community composition remains elusive (5, 6). 2021-04-01 · The extremely low decomposition rate of SOM in mangrove forests is believed to be caused by low oxygen and nutrient availability as well as recalcitrant biomass from mangrove. However, only a few studies have addressed the microbial mechanism that plays a key role in the decomposition of SOM. 2017-01-12 · Crop residue quality and quantity have contrasting effects on soil organic matter (SOM) decomposition, but the mechanisms explaining such priming effect (PE) are still elusive.

In turn, both carbon inputs through roots and litter and outputs through microbial decomposition are intimately linked to soil structure. These aspects will also be 

Full Record; Other Related Research Soil carbon stocks reflect a balance between microbial decomposition of organic carbon and stabilisation of microbial assimilated carbon. The balance can shift under altered environmental conditions [3], and new research suggests that knowledge of microbial physiology may be critical for projecting changes in soil carbon and improving the prognosis of climate change feedbacks [4,5,6,7].

Decomposition begins at the moment of death, caused by two factors: 1.) autolysis, the breaking down of tissues by the body's own internal chemicals and enzymes, and 2.) putrefaction, the breakdown of tissues by bacteria. Microbial decomposition is often highest at intermediate moisture levels, when soils are dry enough that oxygen availability is not limited but not so dry that microbes have insufficient access to water (Chapin et al., 2011a).
