Nitrogen fertilization and cropping system impacts on soil properties and their relationship to crop yield in the central Corn Belt, USA (2008, methodology): “This multivariate tool has been used by many researchers to identify the most sensitive soil and/or topographic properties influencing crop production (Mallarino et al., 1999; Jiang and Thelen, 2004; Kaspar et al., 2004; Blanco-Canqui et al., 2006; Cox et al., 2006).”
Site-specific production functions for variable rate corn nitrogen fertilization (2006, background): “At a field scale, soil water spatial distribution and consequently corn yield are largely determined by topography (Moore et al. 1993; Western et al. 1999; Kravchenko and Bullock 2000; Kaspar et al. 2004).”
Summer Cover Crops Fix Nitrogen, Increase Crop Yield, and Improve Soil–Crop Relationships (2012, background): “Many have studied the effect of soil properties on crop yields (Kravchenko and Bullock, 2000; Kaspar et al., 2004; Cox et al., 2005; Hao et al., 2010), but little data are available on the changes in soil physical parameters and SOC concentration affecting crops yields in intensively managed no-till”
Development of a nitrogen recommendation tool for corn considering static and dynamic variables (2019, background): “, 2002), N dynamics, and thus yield (Kaspar et al., 2004; Kravchenko and Bullock, 2000).”
