Nitrous oxide flux from soil amino acid mineralization
Nitrous oxide (N2O) is a greenhouse gas produced during microbial transformation of soil N that has been implicated in global climate warming. Nitrous oxide efflux from N fertilized soils has been modeled using NO3 K content with a limited success, but predicting N2O production in non-fertilized soils has proven to be much more complex. The present study investigates the contribution of soil am...
متن کاملNitrous Oxide (N2O)-Induced Acute Psychosis.
Nitrous oxide (N2O), commonly referred to as laughing gas, is a colourless, non-flammable, inorganic volatile with psychedelic effects. It has assorted uses among diverse fields: in medicine and dentistry, N2O provides a source of dissociative anaesthesia and analgesia; in the food and automobile industries, N2O serves as a propellant in whipped cream canisters and as an engine booster, respect...
متن کاملGlobal metaanalysis of the nonlinear response of soil nitrous oxide (N2O) emissions to fertilizer nitrogen.
Nitrous oxide (N2O) is a potent greenhouse gas (GHG) that also depletes stratospheric ozone. Nitrogen (N) fertilizer rate is the best single predictor of N2O emissions from agricultural soils, which are responsible for ∼ 50% of the total global anthropogenic flux, but it is a relatively imprecise estimator. Accumulating evidence suggests that the emission response to increasing N input is expon...
متن کاملEvaluation of a closed tunnel for field-scale measurements of nitrous oxide fluxes from an unfertilized grassland soil.
Emissions of the major greenhouse gas NO from soils are characterized by huge spatial variability. An upscaling based on conventional small-scale chamber measurements is thus questionable and may involve a considerable amount of uncertainty. In this feasibility study, we evaluated the applicability of a large, closed tunnel for field-scale measurements of NO fluxes from an unfertilized grasslan...
متن کاملAutomated Near-Continuous Measurement of Carbon Dioxide and Nitrous Oxide Fluxes from Soil
Trace gas fluxes often show temporal variability on the order of hours and accurate quantification may be difficult without continuous or near-continuous measurements. We developed an automated near-continuous trace gas analysis system (NCTGAS) to measure soil-atmosphere gas fluxes on a several-times-per-day basis. In this system, air is circulated in a closed sample loop between fully automate...
