Time, experience and research findings show no-till farming can boost production, prevent soil erosion and transform hayfields and pastures into viable cropland, says Glover Triplett, research professor at Mississippi State University.
Just because strip-tillers got fields stripped in the fall doesn't necessarily mean everything is fine now, says Kevin Kimberley, owner of Kimberley Ag Consulting, Maxwell, Iowa.
Strip-tilling increased soil temperatures and soybean yields vs. no-till in a 2011 Michigan study. Fall and spring strip-till treatments were compared to no-till at one location in southwest Michigan.
Many strip-tillers incorporate application of various fertilizers — nitrogen, phosphate and potash — when strips are being made. Anhydrous ammonia, a common source of nitrogen, can be toxic to germinating seeds and root systems when applied too close to the seed.
Compared to conventional tillage, Floyd, Iowa, strip-tiller Jon Gisleson says his best cornfields perform about the same with strip-till, while his poorer fields yield better.
Strip-tilled soybeans yielded 2 bushels more per acre vs. no-tilled at the highest fertility rate and plant population in a Texas A&M University onfarm trial.
Hybrids that were susceptible and highly susceptible to Goss's Wilt had increased yields under strip-tillage and conventional tillage vs. no-till in a 2010 Monsanto study in Nebraska.
Strip-tilled corn averaged 6 bushels per acre more than no-tilled corn in 2010 onfarm demonstration trials at the Conservation Cropping Systems Project, a 160-acre no-till research farm near Forman, N.D.
