A Proposed Mechanism for the Pulse in Carbon Dioxide Production Commonly Observed Following the Rapid Rewetting of a Dry Soil

  author={Noah Fierer and Joshua P. Schimel},
There is uncertainty about the mechanisms responsible for producing the rewetting CO2 pulse. One proThe rapid rewetting of a dry soil often yields a pulse in soil CO2 posed mechanism is that the pulse of CO2 is largely a production that persists for 2 to 6 d. This phenomenon is a common occurrence in surface soils, yet the mechanism responsible for producresult of the mineralization of nonbiomass soil organic ing the CO2 pulse has not been positively identified. We studied the matter (SOM… Expand

Abstract Rewetting events after a drought produce a pulse of soil respiration (the “Birch Effect”) that leads to a loss of carbon from soil, especially in Mediterranean ecosystems. Two mainExpand

Rapid changes in carbon and phosphorus after rewetting of dry soil
Drying–rewetting (DRW) cycles are important for soil organic matter turnover; however, few studies have considered the short-term effects on nutrient availability. The pulses in soil respiration,Expand
Adding an empirical factor to better represent the rewetting pulse mechanism in a soil biogeochemical model
The rewetting of a dry soil causes a pulse in decomposition of soil organic matter (SOM). This mechanism may dominate carbon (C) and nitrogen (N) cycles in arid, semi-arid and MediterraneanExpand

The influence of precipitation pulses on soil respiration – Assessing the “Birch effect” by stable carbon isotopes
Abstract Sudden pulse-like events of rapidly increasing CO 2 -efflux occur in soils under seasonally dry climates in response to rewetting after drought. These occurrences, termed “Birch effect”, canExpand
