I am having a hard time getting a straight answer for this. 

Is SMS Advanced able to take different data layers (say 2 years of removal rates by yield - each one weighted - plus a soil sample map) and allow piecewise equations to be built - maybe even to accommodate soil type (string)?  I know SST had some limited ability to do this.

Also - a more straight forward question - can SMS Advance use the tri-state or Wisconsin fert derived equations to automate NPK Rx generation?

In my mind, I have a weighted average of {0.2*build + 0.8*expected draw down (minus mineralization by type)}*fudge factor for budget  ---  for a stip till operation of PK. 


My purchase of Advance is conditional on this capability. 

Thanks.
