We provide a general framework for quantifying the effects of genotypic selection prediction accuracy and varying cost ratios of phenotyping to genotyping on the economic performance of genotypic selection relative to traditional phenotypic selection. Economic performance is measured using...

"Stochastic weather and soil conditions are the suggested reasons why farmers tend to apply more than the recommended levels of nitrogen. This study found that uncertainty plays a role in the application decision of farmers but not in the manner typically assumed. Using a time series of field...

While there appear to be costs to farmers of over-applying nitrogen, there is evidence in many regions that farmers are applying nitrogen at levels that exceed those suggested by government extension services. A major reason why farmers would apparently waste money by applying more fertilizer...
