Iowa State University Extension and Outreach is hosting a soil fertility workshop on August 15 from 9 a.m. to 12:00 p.m. with a focus on interpreting soil test results to make more informed fertilizer decisions for both row crops and forage crops. This workshop will be led by Rebecca Vittetoe, ISU Extension Field Agronomist.

“With lower commodity prices, many farmers are looking to trim costs,” said Vittetoe. “For fertilizer, don’t simply trim costs, but rather selectively maximize economic returns to fertilizer expense by understanding how to interpret soil test results and how to use the results to make fertilizer recommendations.”

Even if you already have soil testing and recommendations hired out to an agri-business, you can still gain a very good understanding of how recommendations are made and help you to decide where it makes the most sense to reduce fertilizer costs while improving income.

Topics to be covered during the workshop include the importance of soil testing and interpreting soil test results, calculating nutrient removal rates, and understanding the odds of getting a return on a fertilizer investment.

Feel free to bring along a copy of your soil test results. Pre-register with the Marion County Extension Office by August 7 by calling 641-842-2014 or email lpeterse@iastate.edu. Space is limited to the first 30 registrants.
