Inversion tillage (IT) was performed in 2009 only. In 2010 and 2011 the cost for tillage for all treatments was the cost of noninversion tillage (NIT).
Clover is crimson clover; rye is cereal rye; fallow is winter fallow. In 2011, clover was replanted and rye was only fertilized in 2011. Fallow received an additional application of glyphosate and glufosinate as a winter burndown.
POST and PRE+POST received an additional POST application of glufosinate in 2011.
