This came up again. I went through it before, so I'll be briefer
this time.
Element Oxidation
copper no way
zinc no way
boron no way
molybdenum no way
manganese highly unlikely
iron it's probably already iron III, so no way
Iron, copper, zinc and manganese are usually chelated. The chelating
molecule might be oxidised, which could cause loss of iron. The iron
chelate is usually an iron III chelate, which is accessible to plants,
as far as I know. The problem with iron III when not chelated is the
fact that it precipitates out.
