There is a growing need for research that estimates the potential value to farmers of acquiring and using improved information about spatial variability within their fields. This paper considers the potential value of switching from single rate technologies (SRT) to variable rate technologies...

Develops a framework for incorporating estimation risk into a decision model to determine the optimal amount of soil test information when applying nitrogen fertilizer using a variable rate technology (VRT). Producers should acknowledge that the soil nitrate mapping is a collection of estimates...

Soil sampling has long been advocated as a means of improving the efficiency of fertility management decisions by better matching fertilizer applications with crop nutrient requirements and nutrient availability. Advances in mapping and sensing technologies have renewed interest in soil sampling...
