Joe,

What you are looking for currently cannot be done with I-FARM. I-FARM
has the SSURGO soil database included (currently for 42 states,
including KY) that gives soil and location specific representative
crop yields. There is no crop growth model in I-FARM. For crop growth
simulation you could look at DDSAT, EPIC or WEPP. Nevertheless we
have machinery and (organic) fertilizer data in I-FARM that you could
use in your whole farm model. We also have completed including
100-year simulated weather data for all US weather stations,
generated by CLIGEN, that's available through WEPP. You'll find all
I-FARM data on-line in the 'internal data' section.
