CROPS & SOILS

 

Harvesting and storing of mycotoxin affected corn grain

 

The fungi that cause several corn ear rot diseases can produce mycotoxins, which are chemical substances that can be dangerous to humans and livestock. Corn affected by ear rots requires important management steps to limit yield losses and reduce mycotoxin concentrations.

Storing Mycotoxin-Affected Corn Grain

 
 

Now is a great time to test for Soybean Cyst Nematode

 

Soybean cyst nematode (SCN) remains the most significant yield-limiting pest of soybeans in the United States, causing an estimated $1.5 billion in economic losses annually. Wisconsin runs a free testing program for Soybean Cyst Nematode for farmers

  Episode 2: Gracing Cover Crops Inteseeded into 60" Row Corn

One from the archives: Whereas most grain farmers with a livestock grow crops to feed their cattle, Jeff Gaska a farmer between Beaver Dam and Columbus in Dodge County is trying to grow his cattle to feed his crops. One of the ways he is moving towards this goal is by grazing cover crops interseeded into 60″ row corn. We talk with Jeff about this system, the results that he has had over the last couple of years as well as the approach to how he is determining if it is an economically viable practice for his farm.

DAIRY & LIVESTOCK

 

Fresh Cow Management in Automatic Milking Systems

 

Fresh cows are a critical group on the farm. Cows’ success during the fresh period lays the foundation for their lactation. While many core strategies for fresh cow management apply across both conventional and Automatic Milking Systems (AMS) 🔍, AMS facilities introduce some unique considerations. Understanding these can help farmers optimize cow health, production, and farm workflow.

FARM MANAGEMENT

 

Resilient Farms and Families Responding to Stress

 

The ongoing economic conditions in agriculture are taking a toll on farm families and their rural communities. The associated chronic stress is also impacting mental and physical well-being, relationships, and decision-making. Extension helps farmers, families, businesses, and communities remain resilient by learning how to manage stress and use planning tools to make sound decisions and create a road map for the future.
