Influence of Waiting Time after Insertion of Base Chamber into Soil on Produced Greenhouse Gas Fluxes Chilean J. Agric. Res.
Muñoz,Cristina; Saggar,Surinder; Berben,Peter; Giltrap,Donna; Jha,Neha.
The soil chamber technique is most commonly used for measuring gas exchange between soil surfaces and the atmosphere, to understand regulatory processes relevant to determine the greenhouse gas (GHG) emissions from soils and to improve the emissions inventory of agricultural systems. The chambers are inserted into the soil to avoid the lateral diffusion of the gases. However, soil disturbance caused by chamber insertion causes in degassing and can result in erroneous flux data from measurements made immediately following chamber insertion. Here we assess the effect of soil disturbance associated with the insertion of the chambers on nitrous oxide (N2O) and methane (CH4) fluxes with and without N fertilization, from a New Zealand pasture soil. We collected...
