Iron (Fe) in Soil - pH is a very important factor in interpreting iron tests. In addition, crops vary a great deal in sensitivity to iron deficiency. Normally a medium level would be adequate for most soils. If iron is needed it would be best applied foliar.
Soil Trace elements include : iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn).
