Subject: RE: copper uptake in wheat



Scottville, 49454 Northwest Michigan

Are you asking what amount of copper and zinc a wheat crop will use?

If so.... I use AgPHD's fertilizer removal app that I've installed on my smart phone for those numbers.  For an old guy like myself, I actually find it to be very user friendly.

At-any-rate... a 100 bushel crop of winter wheat will use .09 pounds of copper.   It will also use .52 pounds of zinc.   These numbers are for both the grain and stover.   The wheat crop still needs those amounts of zinc and copper, even if you don't harvest the straw.  But there would be return to the soil of .26 pounds of zinc and .03 pounds of copper if you don't harvest the straw.
