An Index to Describe Potential Yield Increases From Precision Agriculture Technologies.

Many different technologies for describing site variability have been examined, yet only a few are offered commercially today, and little effort has been expended thus far to compare the effectiveness of these methods for various soils and cropping systems.  This poster describes a new index (Precision Ag Potential) that allows comparison of various methods for creating management zones.  This index has also proven effective as a means to rank fields in terms of their relative response to precision ag technologies using these methods.  

This poster also describes a method to create landscape (LSP) zones from accurate elevation datasets, where the elevation of each pixel is compared to its neighbors.  These LSP zones have performed exceptionally well for describing yield potential for many different cropping systems.  LSP has also proven effective for describing differential soil moisture content and re-distribution of water and, as such, can be used for decisions driven by relative soil moisture levels.
