“…Diversifying crop options may increase the resiliency of agroecosystems (Lin, 2011) and stabilize cropping systems vulnerable to a changing climate (Altieri et al, 2015) through agronomic (Johnston et al, 2005;Kirkegaard et al, 2008;Hansen et al, 2012;Seymour et al, 2012;Cutforth et al, 2013;Angus et al, 2015), economic (Entz et al, 2002;Zentner et al, 2002bZentner et al, , 2004, and environmental Gan et al, 2011;Davis et al, 2012) benefits. In the summer-dominate precipitation region of the North American Great Plains, soil conservation practices have enabled crop intensification through fallow replacement (Lafond et al, 1992;Anderson et al, 2003), which has increased opportunities to diversify crops (Halvorson et al, 1999;Zentner et al, 2002b;Tanaka et al, 2005;Roberts and Johnston, 2007), enhance N and water use efficiencies (Pikul et al, 2012). In addition to conserving soil water, the reduction or elimination of tillage is a strategy to combat water and wind erosion (Singh et al, 2012;Williams et al, 2014) in combination with continuous annual cropping (Thorne et al, 2003;Feng et al, 2011).…”
