Topics Concerning Programs to Help Schedule Irrigation
There are several ways to manage and schedule your crop irrigation. Each involves collecting and entering data to an analysis tool to help make irrigation decisions.
Computer Software Program for Scheduling Irrigation:
- The Wisconsin Irrigation Scheduling Program (WISP) is a free, research-based program that uses a water budget approach to irrigation scheduling much like balancing a checkbook. This is a web based application that can be accessed anywhere you have an internet connection. Find the program here.
- Find a User Guide to the WISP-2012 HERE. There is also a link on the WISP-2012 program home page.
A Spreadsheet Method to Schedule Irrigation:
- You can enter data into a customized Excel spreadsheet to schedule your irrigation. Find the University of Wisconsin-Extension / NRCS Irrigation Scheduling Spreadsheet (WISS) HERE.
- Find a Quick Guide to the UWEX / NRCS Irrigation Scheduling Spreadsheet (WISS) HERE.

This web page has maps of Reference Evapotranspiration data that can be used to estimate the ET at your location. You can also subscribe to receive ET data daily by email at this link. You will need the latitude and longitude of the field(s)/farm for which you want ET data. Once the email option is setup, you will be automatically set the ET for the previous day during the growing season for up to 13 sites. A good website for determining latitude and longitude is iTouchmap.com. You just need an address and it will determine the latitude and longitude. If you have questions, please contact John Panuska, firstname.lastname@example.org.
