Soil Fertility Workshops to be Held Across the Eastern Part of Iowa

The cost of managing soil fertility in Iowa continues to change, with increased fertilizer input costs and a rising demand for nutrients from higher-yielding crops.
 
To help producers maximize profits, Iowa State University Extension is hosting six workshops from the end of January through February called Soil Testing Interpretations and Recommendations: Maximizing Return on Investment.
 
Extension field agronomist Josh Michel shared that the workshops will lead farmers through the basics of soil testing, analytical tests, calculating crop nutrient removal, understanding return on investment from fertilizer applications, how crop response correlates to soil test levels and what is known about crop response to micronutrients.
 
“These workshops provide producers the skills to best allocate fertilizer input dollars on their farms,” says Virgil Schmitt, field agronomist with ISU Extension. Producers are already thinking about next year’s fertility decisions.”
 
The workshops are designed to help farmers understand their current soil nutrient situation, the amount their crops are using in a growing season and what needs to be added, says Rebecca Vittetoe, another ISU field agronomist who will be presenting at these workshops.
