First Test Interpolation Purpose

• Use existing tested runs to show how changing
  location can influence soil loss.
• Show that there are no more sharp changes due to
  wind station changes
• Show that ANY location change WILL cause a
  different soil loss estimate
• Test the three ways to locate the point of the
  run, Center of the County, Direct enter Lat-Long,
  and Use Map Viewer.

Test Runs for Skip Row Cotton, TX Panhandle
8-11-09

• The following runs were made using a standard
  template from CMZ 19 for Skip Row Cotton in the
  panhandle of TX
• 8 Counties starting with Randall in the N and
  proceeding S to Midland.
• All runs use Amarillo AmA FSL soil
• These runs are based on the centroid location of
  the county

Summary

• The interpolation routine that Fred Fox added to
  the model seems to work very well. There will be
  no sharp breaks when changing locations from
  station to station.
• You should expect to get a slightly different
  soil loss if you do not use the exact same
  location (Lat-Lon).
• Central States are ready to go.
• We could start final testing.
• I think I would like to wait for the new Map
  Viewer, since I have additional work to do in the
  West.
• Still need CCE approval and NHQs blessing.

26
More Training?

• Many of you have suggested that we have
  additional training.
• I can do anything you all want.
• My preference is to do it face to face.
• Jeff suggested two, one in SD for northern
  states, and one in FW for southern?
• I think Jerry said that FW for one meeting would
  be fine.
• The last and most likely is that we will need to
  do it on the net.

27
Things to Cover

• New additions to the model.
• File management
• Updates, (Crop, Operation, and Management System
  and Version updates)
• Troubleshooting
• Checking Templated Crop System Managements. (I
  am not convinced that we have what we need in
  them)
• How to fix out of order operations.
• How to add irrigation
• Close calls should run long.
• Calibration of multi cut crops.
• Develop runs for and test your problem areas
• Organic soils.

28
Time

• Bill and I think 2.5 days. Come on Mon and leave
  on Thru PM.
• May be in Nov or early Dec.
• May depend on SRCs and funding.
