Hosts Jerry Clark and Ashley Olson discuss hazelnuts in the Upper Midwest with guests Jason Fischbach, UW-Extension Agriculture Agent, and Lois Braun, Research Scientist with University of Minnesota. Lois and Jason have coordinated the Upper Midwest Hazelnut Development Initiative since 2007.
Hosts Jerry Clark and Carl Duley discuss industrial hemp with guest Dr. Heather Darby, Extension Agronomy Specialist with the University of Vermont.
We have paid little attention to Pure Live Seed (PLS) in the Midwest because we have generally had high quality seed (greater than 90% germ and 98% purity). But the short forage seed supply has caused some low quality seed to come on the market. To avoid being caught paying market price for low quality […]
When haymaking conditions are poor hay may be rained on or left lying in the field for prolonged time periods due to cool and humid conditions which reduced drying rates. The long drying periods with high humidity allow field growth of mold on the hay.
There has been considerable interest in growing oilseed radish as a cover crop in Wisconsin due to claimed benefits such as alleviating soil compaction and scavenging excess plant nutrients.
Difficult alfalfa harvesting conditions sometimes result in farmers being off schedule for late summer harvesting alfalfa. This raises the question of best cutting management of alfalfa harvest as the end of summer approaches. If we want good winter survival and rapid greenup for good yield next year, alfalfa must either: This has resulted in the […]
The plant density that maximizes corn grain and silage yield has been increasing through time. The economic optimum plant density is a function of corn yield and quality responses, seed cost, and grain or silage price. The economic plant density is lower than the plant density that maximizes yield.

Introduction It’s early May, you’re looking at a rather marginal alfalfa stand, the haylage silo is nearly empty, and you generally use some corn silage in the dairy ration. Here are the options: Kill (plow or spray) the alfalfa stand now and plant a full-season corn hybrid, control perennial grasses and broadleaves with a post-emergence […]

We introduced Relative Forage Quality as an improvement to RFV in 2002. We released the term to better estimate energy and intake and to do it in accordance with NRC Nutrition Requirements for Dairy Animals released in 2001.
“Cut alfalfa at late bud for optimum quality.” We’ve heard this statement, or a similar one, many times over the past 10 to 15 years. Although forage quality is strongly correlated to morphological stage (for example, late-bud or first flower), many years of monitoring the forage quality of a standing crop has taught us that environment plays an important role in what the actual forage quality might be at a specific stage of maturity.
