Frost damage to alfalfa
The cold temperatures in early spring can cause some frost damage to alfalfa. Following are recommendations for evaluating damage and taking action.
The Cutting Edge Podcast Episode #32: Mint Production (For Oil)
Four experts from Indiana join us for a conversation on growing peppermint and spearmint for oil. Doug Matthys is a mint farmer in South Bend, Indiana at Shady Lane Farms, a fourth-generation family farm growing mint on about 1000 acres. Dr. Elizabeth Long, Assistant Professor in the Department of Entymology at Purdue University, studies plant-insect […]
Update on corn shredlage for dairy cows
There continues to be a lot of interest in corn silage harvested with a self-propelled forage harvester (SPFH) equipped with an aftermarket processor having cross-grooved processing rolls set for 2- to 3-mm roll gap and greater roll speed differential than has typically been used (32% versus 21%). Also, the developer of this processor recommends that […]
Field Notes Episode 3: Introduction to Bale Grazing
With winter on the horizon, ensuring that your bags, bunkers, and silos are full to brim is a ready solution for easing worries about winter feed supply. But, for some farmers, the solution to winter feeding and storage is out in the field. We talk bale grazing with Jason Cavadini who, in addition to being the state grazing specialist with Extension, grazes beef cattle near Marshfield and Lynn Johnson a farmer and grazing consultant with the Northwest Grazing Network.
The Cutting Edge Podcast Episode #31: Haskaps (aka Honeyberries)
A conversation with two experts on haskaps (aka honeyberries). First up is Bernis Ingvaldson, who owns and operates The Honeyberry Farm with her husband Jim in Bagley, MN, about two hours south of the Canadian border. They grow about two acres of honeyberries along with many other alternative fruit crops. Next is a conversation with […]
Field Notes Episode 2: Winter Cover Crops
As fall arrives, farmers turn to harvest. Once the dust settles, some fields lay bare while others show signs of life heading into winter. We talk with Kevin Shelley of UW-Madison’s Nutrient and Pest Management program and Scott Carlson, a farmer in northwestern Wisconsin, about the benefits, challenges, and choices of planting winter cover crops.

Frost Seeding Legumes and Grasses into Established Pastures
Frost seeding legumes and grasses is common means to improve forage yield or change the species composition of a pasture. Frost seeding offers several potential advantages: the ability to establish forage in an undisturbed sod, a reduced need for labor and energy compared to conventional seeding methods, the ability to establish forages with minimum equipment investment, a shortened “non-grazing” period, and a means to maintain stands at productive levels with both grasses and legumes.
Understanding Autotoxicity in Alfalfa
Alfalfa can remain productive in stands from four to ten years or more, but as plant population declines renovation eventually becomes necessary. Alfalfa is commonly grown in rotation with grain crops, however, continuous production is desirable in many areas, particularly on soils that are marginal for economic grain production. Reseeding alfalfa immediately following alfalfa is not recommended in most states due to the negative effects of autotoxicity, seedling disease and insect pests which can build up in old stands. A rotation interval is commonly recommended between killing an old stand of alfalfa and reseeding new alfalfa to help insure successful establishment.
Late Summer Planting Legumes to Produce Nitrogen Credits for Next Year
The high price of nitrogen fertilizer has increased interest in planting a legume crop after wheat or canning crop harvest as a green manure to provide some nitrogen credits for next year’s crop. This practice can provide some nitrogen and organic matter as well as increase ground cover to reduce erosion from fields. However, it may not be cost effective.
