The Iowa Learning Farms (ILF) conservation webinar taking place March 15 at noon CDT will feature Daniel Kaiser, associate professor at the University of Minnesota. Kaiser’s focuses on the evaluation of fertilizer guidelines for major agronomic crops grown in Minnesota. One key area has been the development of sulfur guidelines including rate, timing and source of application to facilitate crop productivity.

Iowa Learning Farms is an Iowa State University Extension and Outreach conservation and water quality education program.

In the webinar, “Choosing the Right Source of Sulfur,” Kaiser will discuss the importance of sulfur application and availability to plants in corn, soybean and alfalfa crops. Drawing on his research which compares the effects of different sources of sulfur on crop yields, Kaiser will discuss data showing if and when elemental sulfur oxidizes to plant available forms necessary for utilization by crops. He will also provide insights into the need for better widespread understanding of sulfur forms and application practices.

“I don’t think farmers always know what source of sulfur is being applied to their field, and therefore may not be aware whether the sulfur being applied will be available at the time a crop needs it,” said Kaiser. “It is critical that farmers choose the correct source of sulfur to ensure that it will have a significant impact on crop yields.”

Participants are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
