Alfalfa growers are thinking about dry weather last fall related to building root reserves, cold weather, snow, winter rain, ice, spring freeze/thaw. The central part of Minnesota should be in better shape generally than some other areas, and damage could be minimal.  Stand assessments can be made when the alfalfa has had a chance to get to be about 6 inches tall. That might be close to May 1 or the first week of May depending on how spring unfolds. Alfalfa growers should always have a plan for where they would plant alfalfa next as needed; and where alfalfa is terminated to make use of nitrogen credits in meeting nutrient needs for the next crop.   

Stems counts can be useful in the spring. It's also helpful to dig out and examine tap roots to a depth of 6 inches or so in several locations in fields. Roots can be cut lengthwise. Health roots are white and firm. It's not unusual to find some browning on the inside of roots and crowns as stands get older.

Regional Extension Educators Doug Holen, Phil Glogoza, and U of M forage researcher Craig Sheaffer off a more complete discussion of this topic at the Minnesota Crop News website:  http://blog.lib.umn.edu/efans/cropnews or search for "Minnesota Extension Crop News". 

A picture sheet discussion of internal root conditions can be found at http://learningstore.uwex.edu/assets/pdfs/a3620.pdf or search for "Wisconsin Extension Alfalfa Stand Assessment."
