Daily nitrous oxide fluxes in response to nitrogen fertilizer
Nitrous oxide fluxes where measured from fields receiving multiple rates of fertilizer application to estimate the total nitrous oxide released as a function of fertilization.
This datatable is part of the Non linear nitrous oxide response to nitrogen fertilizer dataset. A compilation of data from John Hoben’s thesis work.
Six rates of nitrogen fertilizer (0-225 kg N ha-1) were broadcast and incorporated prior to planting on commercially farmed fields in Michigan at four farms and one experiment station. All sites were planted to corn and studied in 2007 and 2008.
Site abbreviations are as follows: Kellogg Biological Station, KB; Mason, MA; Stockbridge, SB; Fairgrove, T1; Reese, T2.
Please refer to the thesis (2009) and primary publication (2010) for additional information.
