Description
| These data were collected in order to explore the effect of liming on nitrous oxide (N2O) emissions from plant residues in an acidic soil.
Field data of N2O fluxes measured by a robotized chamber device after ploughing of temporary grassland plots with two contrasting soil pH. Treatments were a grass mixture, a red clover-grass mixture and red clover in pure stand, factorially combined with two soil pH treatments: control (pH-aq roughly 5.1) and limed (pH aq roughly 6). In addition, plots of a white clover-grass mixture on low pH soil only, and of the red clover-grass mixture were split into two nitrogen fertiliser treatments: a low dose and a normal dose, whereas the grass mixture received only normal dose nitrogen fertilizer and red clover in pure stand received no nitrogen fertilizer. Nitrogen treatments occurred during the growing season previous to ploughing. Fluxes were also measured in spring and late summer 2018. Most emissions occurred during the winter period, after ploughing in September 2018 to early April 2019. The field was exposed to freeze-thaw, snow cover, and snow melting. Plot-wise soil pH measurement in Calcium chloride or in water are included. In addition, also mineral soil N (ammonium and nitrate) are provided on selected dates.
These data are presented and discussed in the companion article. They are provided here for transparency. The data may also be useful for comparisons with further studies on the effect of soil pH on nitrous oxide emissions and on N2O sampling methodologies. They provide also information on soil mineral N after ploughing of 3 y old forage leys. (2021-06-09) |
