Sentences with phrase «soil microbial respiration»

Other effects of SRM are expected to reduce soil microbial respiration, enhancing carbon storage in soils too.

Not exact matches

They write, «We show that anaerobic microsites are important regulators of soil carbon persistence, shifting microbial metabolism to less efficient anaerobic respiration and selectively protecting otherwise bioavailable, reduced organic compounds such as lipids and waxes from decomposition.

I also examine the partitioning of soil respiration into microbial and root respiration.

Estimates are that microbial respiration will speed up as the soil warms, resulting in a net flux of CO2 to the atmosphere.

One example is the global soil reservoir of organic carbon (which is not a single «pool», but which is made up of many components, some which are very labile (rapid turnover via microbial and root respiration) and some of which are very long - lived (humic material).

Estimates are that microbial respiration will speed up as the soil warms, resulting in a net flux of CO2 to the atmosphere.

Carbon fixed into plants is then cycled through plant tissues, litter and soil carbon and can be released back into the atmosphere by plant, microbial and animal respiration and other processes (e.g. forest fires) on a very wide range of time scales (seconds to millennia).

The present paper presents a mathematical analysis of a tipping point or runaway feedback that can arise when the heat from microbial respiration is generated more rapidly than it can escape from the soil to the atmosphere.

After the hurricane had passed, soil carbon - dioxide efflux — due to microbial and plant respiration — increased while gross primary productivity decreased.
