Subject: RE: Fertility Rx software

You can do that in our software GeoPard Ag. There are several options to create fertility Rx based on yield data: 

  1. Equation based analytics: use template equations from Universities or create your own. Each variable could be mapped to vector (soil sampling attributes, EC, yield, etc) or raster (derivatives from imagery or topography). Examples are below.
  2. Multi-layer analytics in weighed manner: Aggregate several data layers, set weights to each. Also negative weight could be set (e.g. higher LIDAR slope - lower yield potential)
  3. Single-layer Rx zones based on Yield data , tutorial 

It seems that you more think about #1. You can drop me an email or create a demo request at the website, will assist with that for free.
