Heavy rainfall and flooding in many Midwest fields in 1993 prompted farmers and others to ask about soil compaction and the need for preplant tillage prior to planting the following year. On five Iowa farms that experienced excessive rainfall, U.S. Department of Agriculture researchers compared shallow, moderate and deep tillage and evaluated their effects on soil compaction and crop yields.
In a 17-year Nebraska study, researchers found that conservation tillage gave higher irrigated corn yields and profits than tilled plantings. The average yield increase was 4 bushels per acre, while the three conservation tillage treatments resulted in $8 to $16 per acre less tillage costs than the conventional disc tillage treatment. The conservation tillage treatments were ridge-till, rotary-till and slot-plant, while tilled treatments consisted of chisel, disc or lister operations for the furrow-irrigated continuous corn plantings.
Jay Dahl, Welding/Fabrication-Sales at Calmer Corn Heads, introduces Calmer Corn Heads' 12-Row, 30-Inch corn head and explains the advantages of using the 10-Blade BT Chopper Chopping Roll for combining corn. He also talks about the adjustments they made on the corn head when combining downed corn after the August 2020 wind storms.
The Summit, formerly known as the Conservation Tillage Conference (CTC), features keynote speakers, breakout sessions, table talks and vendor booths. Attendees who stay for the entire conference will be offered CCA continuing education units (CEUs).
Finding solutions to the problems farmers face is what inspired Harry and Etta Yetter to open a small machine shop in west central Illinois in the 1930s. Today, four generations later, Yetter continues the tradition of solving agricultural problems to meet the needs of producers all over the world.
