• Management Effects on Relationships of Crop Yields with Topography Represented by Wetness Index and Precipitation (2008, background): “Th ese variations are oft en associated with the prevailing weather conditions during the growing season of each particular year (Halvorson and Doll, 1991; Jaynes and Colvin, 1997; Kravchenko and Bullock, 2000; Jaynes et al., 2003; Kaspar et al., 2003).”
• Comparing estimates of climate change impacts from process-based and statistical crop models (2017, background): “In some environments, the ranking of a soil for grain yield can reverse depending on rainfall (Wong and Asseng 2006, Kaspar et al 2003).”
• Identifying potential soybean management zones from multi-year yield data (2005, unknown): “Yields were markedly more uniform in the drier years of 1992 and 1994, which was also observed for corn yields in this field (Jaynes et al., 2002; Kaspar et al., 2003).”
• Site-specific production functions for variable rate corn nitrogen fertilization (2006, result): “Our results agree with Kaspar et al. (2003) who reported a significantly positive correlation between corn yield and slope during wet years.”
• Lessons from nearly 20 years of Precision Agriculture research, development, and adoption as a guide to its appropriate application (2009, unknown): “Similarities between this work and theAustralianwork ofCox (1997) andCox et al. (1997, 1999) were evident, notwithstanding the different objectives of ameliorating soil pH in the USA and sodicity in Australia.”
• Economic Analysis of Spatial-Temporal Patterns in Corn and Soybean Response to Nitrogen and Phosphorus (2006, methodology): “Kasper et al. (2003) used 6 yr of corn data to estimate corn response with respect to topography and elevation.”
• Variable rate fertilization in citrus: a long term study (2017, background): “(2011) and Kaspar et al. (2003) in cereal crops, when a strong relationship was found in dryer years.”
