Wheat foliar feeding advice
North Dakota State University and University of Minnesota wheat experts recently offered advice on boosting protein levels and comparing products and practices on the farm.
If wheat growth stage is not yet jointing, stream on ammonium sulfate urea ammonium nitrate (UAN) and ammonium thiosulfate (ATS) or ammonium sulfate (AS), advises Dave Franzen, North Dakota State University Extension soils specialist. You can achieve both yield and protein increases.
If wheat growth stage is jointing, you could stream on UAN and ATS or AS and achieve some protein increase, he says.
If wheat is flag leaf, wait until immediately post-anthesis and apply 30 pounds N per acre as UAN or urea solution, with 3 pounds N per acre as an AS solution. The result will be an increase in protein most of the time, Franzen says.
Jochum Weirsma, a U of M Extension agronomist, says doing your own on-farm tests is OK, but it takes extra time and work to do research right and produce reliable, meaningful results. Bad data is worse than no data, Wiersma says.
