UPDATE Tuesday May 10 Evening
The Alfalfa Harvest Alert Project is a joint effort of Central MN Forage Council, U of M Extension staff, and cooperating farmers and agribusinesses.
Click on May 9 2016 Data for a list of data collected as about 6 p.m. on Monday May 9. Due to the variation of some samples going through the mail and some samples being taken direct to labs, this report includes some most recent samples on May 5 and some on May 9. All samples are still in the vegetative stage. Some fields are measuring tallest stems at 20 inches or more. Early bud formation could start showing up in some more advanced fields by the end of this week or early next week. Obviously there is variation with soil types, field management, and local weather variables. Past experience counts.
I will update the linked document as we get more data for May 9.
