Alfalfa Update

Extension Field Agronomist Joel DeJong reports “I am not certain we have a good window of opportunity for harvesting alfalfa soon, but I hope so”. He was out in a couple of alfalfa fields near Le Mars yesterday (Wednesday), and the stems measured  25” tall, and were in the bud stage.  That would give it a RFV today of 176. In review, making haylage reduces the final RFV by 15 units, or making dry hay would cost about 25 RFV units.  It is generally recommended to harvest alfalfa at about 150 RFV for milking dairy herds and 125 RFV for heifers, stocker cattle and lactating beef cattle. Find more information about the PEAQ quality assessment model found here. While out there, he noticed low levels of alfalfa weevils feeding on the leaves. Scouting detail, thresholds, pictures and more can be found in this ISU ICM article titled “Alfalfa Weevils Active in Northern Iowa.”

Weekly Hay Auction Report

Iowa hay offerings were tighter this past week and prices were higher even though
the quality was lower.  Supreme alfalfa could only be found in small squares
and that supply, baled last year, was tight.  The supply of large squares was
limited, regardless of the quality of hay.  The end of this week in Iowa was
wet with the forecast for the rest of May also indicating wide spread rain and 
slightly below normal for temperatures.  While this weather pattern may encourage
the growth of pastures, it wrecks havoc in the harvesting of first cutting.

Weekly Hay Auction Report

Hay and straw were more available this past week in Iowa, but the majority 
of it was lower quality.  Some of the offerings may have been stored for an
extended period of time.  Prices continue to edge higher as end users continue 
scramble for both hay and straw to get them through a wetter and cooler spring.

Evaluate Alfalfa Fields For Winter Injury

This week ISUEO Field Agronomist Joel DeJong notes that he has been in a few older alfalfa stands that did not survive the winter very well. Sometimes they looked OK from the road, but when in them you could see that the stands were thinned significantly by the winter we just experienced.
