PEAQ Forages Monitor

Predictive Equations for Alfalfa Quality (PEAQ) Stick monitoring will be conducted by the UW-Madison Division of Extension Crops & Soils and Dairy Educators of Grant, Green, Iowa, and Lafayette county. 

PEAQ is a method developed by the University of Wisconsin to provide an estimate of the relative feed value of first cutting alfalfa based on crop height and maturity.  Our goal is that this information will help forage producers and agronomy professionals track the growth and development of alfalfa in their area so they know when to check their own fields to target their preferred quality while maximizing tonnage.

Samples will be collected on Mondays and Thursdays with results posted online Tuesdays and Fridays during the month of May.

For more information, contact Jordyn Sattler, Crops and Soils Educator at jordyn.sattler@wisc.edu or by contacting the Green County Extension Office at 608-328-9440.
