A team of Harrison County farmers, landowners, agronomists, crop advisers, bankers, seed and chemical company representatives, and Iowa State University Extension and Outreach specialists are addressing the increasing threat of herbicide resistant weeds, including Palmer amaranth.
The 2017 Iowa Farm and Rural Life Poll surveyed Iowa farmers to ask them if they have herbicide resistant weeds in their fields, to learn about perspectives on the manageability of major weeds, and to measure their level of concern about herbicide resistance.
Updates on the latest crop production products and recommendations are the featured topics at Ag Chemical Dealer Updates sponsored by Iowa State University Extension and Outreach in Iowa City, Nov. 21 and Ames, Dec. 13.
The risks of hydrogen sulfide in swine operations have been known for years, but beef operators also need to be aware of the dangers this gas can pose.
High levels of deoxynivalenol (DON), a mycotoxin commonly known as vomitoxin, are being found in grain across the Corn Belt, including eastern Iowa. Contaminated corn is an issue especially in dried distillers grains and solubles (DDGS), according to Erin Bowers, mycotoxin sampling and analysis specialist with Iowa State University.
Winter is here, and with it comes inclement, icy, snowy weather. Many Iowans use deicing salts to rid their properties of snow and ice, and deicing trucks and snowplows also spread chemicals on roads and streets. But these chemicals can have a negative effect on landscape plants.
The regional Corn Nitrogen Rate Calculator website, which has been helping farmers determine profitable nitrogen rates since 2005, now has a new URL, a revised nitrogen response trial database, and is more user-friendly for mobile devices.
The Corn Nitrogen Rate Calculator is available to help farmers find the maximum return to nitrogen fertilizer applications and the most profitable application rate for their farm. Having adequate nitrogen available is critical for corn production, but given the high prices for fertilizer it is important farmers determine the right amount that is needed on their crops.
