North Central Ohio, across the Corn belt ! | Sure you can build Copper levels !!! I have several farms where manure has been hauled for 40 plus years and the copper levels are many times Higher than the fields that have not had copper.
You need to talk to a Consultant or Agronomist that does not sell Products nor work for a company that manufactures, Packages Micro nutrients !!!
I recommend some dry Copper Sulfate on most wheat Top dress and along with the corn, dry Nitrogen most every season as is called for.
I have no clients that use any liquid fertilizer so all Micros are applied in the dry form
In My Opinion you are WAY short on ALL according to your report ? But I do not know your soils nor your weather pattern Nick M |
