My iron content is 10ppm in one plot and 22ppm in another, the OVGPG article says optimum is 46ppm should I worry about raising and if I do will it effect any other minerals.
My zinc levels were low at 2.3ppm but I have added Zinc sulfate at the recommended amount and my pH is 7

Adding 1 40lb bag of Ironite to 1000sq ft. will raise your fe ppm by about 38. It also contains trace minerals so check them.

ok,, so here's another question,, on the same lines,, i also added 40 lbs ironite,, this fall,, fe ppm was at 6,, low,, yes, so where should my manganese levels be in accordance to the fe levels, ?? curt

I would say the manganese should be about 2/3 the iron.

Iron always has to be higher than manganese; when manganese is higher than iron it will tie up the iron. Over 75% cation saturation calcium will start tying up iron. Ferrous sulfate (aka iron sulfate) is the best form to apply
100#/acre ferrous sulfate will raise iron levels 10.5 ppm.
Thats a copy and paste from this page http://woodleaffarm.com/enlivening-soil/
but does adding iron changes PH ?

ok,, thx men,, i added 40 lbs of aluminum sulfate and 50 lbs calcium in october,, till it in,, watered hvy for a couple weeks before i added the iron,, let winter run it coarse now,, will add manganese in the spring with what new soil sample tells,, appreciate the ifno,, best and good luck curt

All of our climates and soils are different; but keep in mind that in any soil your leach factor will negate some perceived gains in ppm over the winter.
I agree to wait until spring to "top-dress" your nutrients, esp the ones like Mn that leach quickly.

I came across this article when I was looking for a way to raise my iron levels. I have used this product in the past, but will not use it again. http://www.dirtdoctor.com/Ironite-Story_vq120.htm

With such high cation saturation you should not add Iron-III-Sulfate, which reacts as cation too! ...and produces alums. Phospates/phosphite would be blocked through flocculation with Fe-III-sulfate (like in the clarification plant). With my pH around 6 or below I can use Fe-III-sulfate, when I do not give too much lime. My soil has far too much manganese. It´s better for me, not to raise pH over 6.3 for pumpkins. But I apply only a little Ca when spading up in a autumn. In spring I spray Ca with boron before flowering and magnesium nearly the whole season. And when Xanthoonas bacteria show me the surplus of manganese, I spray iron-citrate. My greenhouse soil is charged with very expensive iron-chelates, where there is too much soilborn manganese. These chelates persist three years at least, but I have to inject them into the soil, because they are not UV-resistant.
