"Emission of nitrous oxide (N2O) from soils is the net result of N2O-producing and consuming processes within the soil, and studying the regulation of these processes in the real soil environment is essential to the understanding of the factors governing N2O emission. In this study, microscale distributions of O-2 and N2O in the soil were investigated to describe how N2O production within, and emission from, soils are regulated by anoxic volumes created by injection of liquid manure," scientists writing in the European Journal of Soil Science report.
"An application device simulating field injection methodology was developed and liquid pig manure was injected at a depth of 5 …
