Description

Nitrous oxide (N2O) is a potent greenhouse gas that plays a key role in climatic forcing contributing to the greenhouse effect by about 4 %, and also contributes to stratospheric ozone depletion. Cattle slurries are commonly applied to agricultural soils, inducing an increase of soil nitrous oxide emissions. Therefore, many procedures were developed for slurry pre-treatment in order to improve soil slurry application and reduce nitrogen losses, namely N2O emissions. The aim of this work was to compare N2O emissions and the kinetic of N organic degradation from treated and untreated cattle-slurry after its incorporation in agricultural soils.
