With much of the U.S. facing conditions similar to those of the 2012 drought, a look back at lessons learned suggests adjusting management plans may help protect no-till yields and increase resilience.
In both wet spring weather and drought conditions, the timing of cover crop termination can have a big impact on soil moisture levels, according to Purdue University.
Kansas State University Extension reviews the yield benefits of drought-tolerant corn hybrids to maximize production per unit of available water in dryland environments.
With so little moisture in the soil in June, it’s conceivable that roots were not capable of taking up most of the N that was traditionally applied at the V6 stage, says Michigan State University Extension.
WITH EXTENSIVE concentrations of livestock production in the Northeast area of the U.S., this hasn’t been an area that’s seen a significant shift to no-till. But with area farmers facing a serious lack of rainfall and new nutrient management rules that practically mandate no-till, there’s more interest now than ever before.
It’s certainly great to see how far soil-moisture profiles have come across the Great Plains over the past year. Looking at the U.S. Drought Monitor, you don’t see a sea of brown and red colors that the government uses to signify severe major drought problems.
In the middle of a very hot and dry summer, such as occurred in many areas during 2013, no-tillers quickly recognize the residue covering the soil is normally cooler and wetter than with soils found in conventionally-tilled fields. They recognize that reducing stress on their no-tilled crops is a major benefit when summer weather turns hot and dry.
DuPont and its Pioneer Hi-Bred agricultural seed unit said a hybrid wheat technology project has been added to its roster of crop research programs that are advancing into deeper development. DuPont currently is largely focused on genetic improvements to corn and soybeans, as well as enhanced canola and rice.
