Data of biomass and N in grass and clover roots, stubbles, and herbage and associated N2O and CO2 emissions, inclusive soil air composition, following autumn ploughing –A field study

Summary

This article presents the detailed data of the soil character- istics, field management, amount and N content of below- (roots + crown) and aboveground (stubble and herbage) grass mixture, red clover and red clover grass swards at the end of the 3rd production year, together with fluxes of greenhouse gas emissions (N2O, CO2 , CH4) and soil air composition (CO2, N2O, CH4, N2 and O2) of a field experiment in Norway. These data supplement the findings presented in the research article “Roots and other residues from ley with or without red clover: quality and effects on N2O Emission Factor in a partly frozen soil following autumn ploughing” (Bleken et al. 2022). For understanding of the effects of incorporating ley above- and belowground residues on cumulative greenhouse emissions refer to article from this research.
