Crops and Soils

The Extension Crops and Soils Program provides timely resources and information to help Wisconsin crop producers and their agricultural consultants manage crops efficiently and profitably.

You can find information on:

  • Crop Production and cropping systems for corn, soybeans, forages, nutrient management, soil science, commercial vegetable, and cover crops.
  • Pest Management: Information on the management of weeds, insects, and disease in Wisconsin cropping systems.
  • Ask Extension: Your opportunity to talk directly with Extension specialists and staff.

Establishing alfalfa following wheat

Look out for herbicide carryover, volunteers in late summer seeding of alfalfa after wheat.
As we head toward the end of summer, it is closing in on time for a late summer establishment of alfalfa. Commonly in Wisconsin, this is done following a wheat crop in the spring. This can lead to a few challenges to consider: residual herbicide carryover and the effects of volunteer wheat on successful establishment.

Giant Ragweed Control- Research Summary

This publication–which was the result of six years (2018-2023) of giant ragweed driven research projects–was conducted by the WiscWeeds team at the Rock County Farm (Janesville, WI) and sponsored by commodity groups and crop protection industry. It will benefit those battling giant ragweed:

Waterhemp control in XTendFlex soybean without dicamba

The Wisconsin Cropping Systems Weed Science program has conducted several research trials investigating postemergence (POST) weed control in XtendFlex soybean systems (dicamba-, glufosinate-, and glyphosate-resistant soybean) without OTT applications of dicamba. Follow link for the full article:

2023 Wisconsin Weed Science Research Report

The purpose of this report is to share the results of corn, soybean, and spring wheat herbicide evaluation research trials conducted by the Wisconsin Cropping Systems Weed Science (WiscWeeds) Program during the 2023 growing season.

“The adoption of cereal rye (Secale cereale) cover crop has triggered the interest of farmers as an additional tool for pigweed
(waterhemp [Amaranthus tuberculatus] and Palmer amaranth [A. palmeri]) management in soybean production systems. Along
with interest in this practice, there have been many questions about how cereal rye can impact other weed management
practices, such as the fate of PRE-emergence (PRE) herbicides in the soil when applied over high cereal rye biomass.” Follow link below to view this multi-state field study.

DON Considerations for Wheat Grown for Livestock Feed

Written by our own Crops & Soils and Livestock Educators, this article is helpful to those who own livestock and wanting to understand what DON (deoxynivalenol or vomitoxin) can affect the small grains grown to feed their livestock. DON is a mycotoxin that is responsible for Fusarium Head Blight (FHB), a disease in small grains. Follow the link to read and learn more:

Email: sbibby@wisc.edu

Sam Bibby serves as Regional Crops Educator, covering La Crosse, Vernon, and Crawford counties. Sam works to address the specific needs of producers and community members related to crop production. Outreach efforts will aim to form a bridge between university lead research and on farm practices.

He attended the University of Wisconsin-Platteville where he earned his undergraduate degree in soil and crop science in 2019. He then attended North Dakota State University and earned his master’s degree in plant science. Sam’s masters research was titled “Corn-Alfalfa Intercropping with Different Row Spacings” and was focused on developing a more profitable way for producers in the Northern Great Plains to establish alfalfa. Most recently, Sam worked for the NDSU Forages and Industrial Crops Program as the Research Specialist and was responsible for designing, managing, and analyzing field trials related to forage and industrial crop production.

Sam’s primary interests lie in conservation, farm technology, intensive crop management, forages, and alternative crops. Sam hopes his background in research and day-to-day farm operations will help him deliver tangible, data driven solutions to growers.
