ST. CLOUD, Minn. — After a long Memorial Day weekend, labs and growers were back in business sending samples for the Alfalfa Harvest Alert Project/ Scissor Cut project. The goal of this project is not to try to name the day that you should harvest. Rather the goal is to encourage growers who are busy with management of other crops to be more strategic with hay crop harvest as it relates to their needs.
Fresh cut samples of alfalfa are collected when height of the stand reaches between 14 and 16 inches tall. Project cooperators will try to sample at least twice a week usually Monday and Thursday until harvest. Clipped samples are tested to determine Relative Feed Value (RFV), Neutral Detergent Fiber (NDF), and other alfalfa quality factors related to harvest decisions. Quality and maturity will also be estimated through an equation called the “Predictive Equation for Alfalfa Quality” (PEAQ). This process uses the stage of maturity and height of the tallest stems to estimate RFV and NDF.
