County nitrogen reduction planning tool spreadsheet for groundwater, last updated on 10/3/23. Note: This is a watershed-scale tool intended for an audience of local water resource managers, not a farm-level decision tool. It will probably be necessary to save the spreadsheet to your own computer and then re-open it to allow the macros in it to work properly:
Tool for Southwestern Minnesota (xlsm)
Tool for Central Sands area of Minnesota (xlsm)
Tool for Southeastern Minnesota (xlsm)
The Nitrogen Alternative Management Planning Groundwater Tool spreadsheets were developed under a contract between the Minnesota Department of Agriculture and the University of Minnesota, as part of a comprehensive study of groundwater nitrogen conditions, sources, trends and solutions.
