Manganese Deficiency in Soybeans

Soybeans in this field are chlorotic, likely because of manganese deficiency.  One possible cause it glyphosate.  The Pioneer Seeds article suggests that the solution may be as simple as how chemicals are mixed.  Some people say this is not a yield problem, but it looks pretty bad to me at least inthis field.  Any easy solution is to not use glyphosate every year.
