Soil Compaction School to Be Held at Iowa State Field Extension Education Laboratory near Boone

Oct 14, 2025

By Kapil Arora and Mehari Tekeste

Soil compaction caused by farm machinery and field traffic will be discussed at an upcoming Soil Compaction School event on Nov. 14. The event will cover methods to minimize compaction and mitigate any soil compaction that may have already occurred.

“Soil compaction can significantly impact crop yields, as it can push soil particles together, reducing soil infiltration capacities and increasing resistance to crop root penetration and development,” said Kapil Arora, field agricultural engineer with Iowa State University Extension and Outreach. “This, in turn, impacts moisture and nutrient availability to crop plants for growth and development, even under favorable weather conditions. Ten to 20 percent yield loss has been reported under unfavorable weather conditions.”

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
