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.
No-tiller David Groff from Cedar Meadow Farm in Holtwood, Pa., talks about the farm’s experience this year no-tilling hemp and the cover-crop mix and fertility plan they followed during the growing season.
Attend the 2020: Vision and Beyond Symposium to hear from leaders in regenerative agriculture and producers about their experience implementing on intercropping, no-till equipment, soil health testing, winter grazing, and more.
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.
Needham Ag understands the role of technology in making better use of limited resources within a specific environment by drawing on a wealth of global experience to overcome the challenges facing today's farmers, manufacturers and dealers.
