Alfalfa Forage Quality
Alfalfa Forage Quality Using PEAQ Readings and Scissor Cuts
First crop alfalfa accounts for the largest quantity of forage over the growing season. Targeting optimum forage quality not only helps growers meet their forage needs but also sets them up on a cutting schedule that can help them meet their needs over the course of three to four cuttings. The UW Madison Division of Extension in partnership with the Fond du Lac County Forage council and the Midwest Forage Association will be collecting PEAQ stick measurements, crop maturity, crop height and scissor cut forage analysis over the next 4-5 weeks following this schedule:
- May 5 – PEAQ Stick Measurements
- May 12 – PEAQ Stick, Scissor Clip Results (as long as crop has reached 12″)
- May 19 – PEAQ Stick, Scissor Clip Results
- May 27 – PEAQ Stick, Scissor Clip Results
- June 2 – PEAQ Stick, Scissor Clip Results (if crop is not harvested)
Alfalfa Quality Measurement will be taken in the following areas:
- Oostburg
- Plymouth
- Taycheedah
- Kewaskum
- Brownsville
- Ripon
Results will be posted on this site the following day (Tuesday or Wednesday) and will also be uploaded to this site: https://go.wisc.edu/AlfalfaHarvestAlert which is a collaboration between the UW Madison Division of Extension and University of Minnesota Extension

May 5, 2025 Alfalfa Quality Report
- Cool weather (particularly overnight) has kept alfalfa growth at bay. All sites were well behind 2024 growth at this point in time.
- Next week’s report should include scissor cut lab data for most sites.
- While scouting crop for growth/maturity – keep your eye out for alfalfa pests. First Crop Insect Scouting in Alfalfa
