Identifying the holes where profits leak away is a talent Kenton, Ohio, no-tiller Dave Lotz has nearly perfected during almost 25 years of no-till trial and error.
No-tilling corn and soybeans presents many challenges to producers across the country, especially within continuous corn and other high-residue environments.
Ongoing research at the University of Wisconsin has given us insight on differences between chisel plow, strip-till and no-till. Dick Wolkowski of the Department of Soil Science has researched these conservation-tillage systems for more than 10 years.
As more producers move toward no-till systems for conservation compliance and to reduce costs, some have chosen strip-till. Research shows strip-till corn yields have been slightly higher and more consistent than no-till in some areas.
Many producers may ask how continuous cropping can work in a semi-arid environment. For southeastern Montana farmer and rancher Ben Minow, the question isn’t if producers can make it work, it’s how anyone could economically raise a crop any other way.
With fertilizer prices doubling and even tripling, there has never been a more opportune time to invest in soil testing. With total phosphorus and potassium crop removal maintenance in the range of $75 to $125 per acre, it makes good sense to have accurate soil test information.
Tougher stalks from Bt corn hybrids, increased use of fungicides and the chance to trim fertilizer needs are bringing more attention to effective residue management at harvesttime.
Under the no-till conditions outlined above and with this style of seeding unit, my thought is not to try to chop or cut the residue. In my opinion, standing residue leads to more effective cutting with disc seeders that are used under low-moisture conditions.
