Recently, it has come to my attention that some ag suppliers are promoting foliar applications of micro-nutrients like magnesium, iron, copper, manganese to increase wheat protein. I know of no studies to support this application. There is no logical reason to believe that application of micro-nutrients should increase wheat protein. On the other hand, there are many studies to support the application of the 10 gal / acre, 28% application post-anthesis to increase protein. I would encourage growers and suppliers not to use micro-nutrients to increase grain protein, but to follow the proven recipe described in the last three crop and pest reports.
