C orn residue can be removed from fields following grain harvest for several non-mutually exclusive reasons. Residues may be grazed in field or harvested to provide feed for livestock (Larson et al., 2011; Rakkar et al., 2017; Schmer et al., 2017). In areas with cooler and wetter climates, such as the northern Corn Belt, stover can be removed to prepare for the next crop (Allmaras et al., 1964; Karlen et al., 2014), but in drier locations this may not occur (Jin et al., 2015). Residues can be harvested to help control pests and crop diseases (Cook et al., 1978; Sindelar et al., 2013) or can be incorporated into the soil through tillage (Bailey and Lazarovits, 2003; Shelton et al., 1995). Finally, residues can be removed as a bioenergy feedstock (USDOE, 2016, 2017). When corn residues are harvested from the field they are commonly referred to as stover, and this term is used throughout this paper. Available data suggest harvesting corn stover is not as common as other field residue management operations including grazing and tilling. Estimates using 2010 Agricultural Resource Management Survey (ARMS) data indicate 4.06 million ha of corn residues were grazed. Stover was removed and baled at an average rate of 3.6 Mg ha-1 from 0.81 million ha that comprised 2% of the corn area in the 19 surveyed states (Schmer et al., 2017). Managing surface residues through tillage is more common than harvesting them. National data suggest some form of tillage, excluding no-till, occurred on approximately 74% of corn acres. Pest management practices including tilling, chopping, mowing, and burning were used on approximately 44% of planted corn areas (USDA ERS, 2017). An emerging use for corn stover that could significantly increase the harvested area is as feedstock for bioenergy or bioproduct markets. Corn stover was identified as a key resource for achieving U.S. renewable fuel standard goals (Keeler et al., 2013). Depending on price, corn stover could supply up to 136 million Mg yr-1 (USDOE, 2016), but currently only 2.9 million Mg yr-1 are being harvested (Schmer et al., 2017). Regardless of the end use, excessive crop residue removal can increase soil erosion and degrade soil functions. Substantial research efforts, including the Regional Feedstock Partnership within the Sun Grant Initiative (Owens et al., 2016), have evaluated how soils may be impacted by harvesting corn stover and other crop residues. When left in the field, plant residues protect
