Pennsylvania will have a mandantory nutrient management plan(NMP)requirement by Oct 1996. All livestock activities with over 2K lbs of animal weight per acre will be required to submit a NMP. Perhaps you may want some information if you would be interested in building a program for this type of requirement. There are some versions out there, but as far as I know they do not address all the areas of reporting. Let me know if your interested, if not, no problem.
