Grain yields in response to fertilizer application

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Grain yields were measured as part of the effort to quantify nitrous oxide production in response to fertilizer inputs.

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.
