This must be an illness caused by the excess iron but I'm not having any luck finding it. :o(
...en el caso de que exista hierro reducido en grandes cantidades, es necesario tomar medidas para evitar ferrosis en las hojas (manchas amarillentas) y bajos rendimientos de cultivo.

iron toxicity
As discussed at length, although "ferrosis" commonly means "iron deficiency", in this particular case it seems to mean "iron toxicity": a disorder caused by excessive uptake of iron, arising from the high level of reduced iron in the soil, mentioned in the source text.

In that case, please check the link below as it discusses this in plants.

iron deficiency / iron chlorosis
This is really what it means, as the reference to "hierro reducido" in your source text indicates, and yellowish marks on leaves are a symptom of it, so that's what I'd put:
"Yellowish leaves a clue to iron deficiency"
http://www.winnipegfreepress.com/historic/31374959.html
It can be called iron chlorosis:
"Iron deficiency (iron chlorosis) is a common problem in Australian gardens [...]
Iron deficiency first appears as a ‘veiny’ look on new growth, with a darker green pigmentation retained on the leaf veins and the rest of the leaf developing a pale or yellowish green colour."

So not excess iron: just the opposite in fact!

Thank you all for your help on this. It really was a tricky one. :o)

So if this is about too much iron, as I say, I think you'd be fine with "iron toxicity". I must admit, though, that I'm still in some doubt about this and I just wonder whether, either because of high pH or water in the soil, the problem is depressed iron uptake, despite all the reduced iron around. I just don't know.
http://homeguides.sfgate.com/effect-excess-iron-plants-48927...
Maybe "ferrosis" really means an iron disorder; that disorder is usually deficiency, but sometimes it's excess, and maybe that's the case here.
I have only found "ferrosis" with the meaning of iron deficiency, applied to plants, and yellowing of leaves is the classic symptom of iron deficiency, so everything seemed to fit. BUT "hierro reducido en grandes cantidades" really does seem to mean a lot of reduced iron or ferrous oxide. Moreover, when you look this passage up it is talking about gleysols, and these do seem to be high in iron:
"Where anaerobic organisms reduce ferric oxide to ferrous oxide, the reduced mineral compounds produce the gley soil typical color."
http://en.wikipedia.org/wiki/Gleysols
I wondered whether, paradoxically, the high level of reduced iron might increase the pH, which would actually reduce the iron uptake. I'm not sure, but I don't think that's the case, and it seems that ferrous iron or reduced iron is actually easy for plants to absorb.
So it does rather look as though "ferrosis" could mean iron toxicity here. This does exist, at least in some plants, though it's fairly rare. The symptoms seem to be bronzing rather than yellowing, but maybe the "manchas amarillentas" are consistent with excess iron.
Thanks for taking the time to answer. I understood the phrase to mean too much Fe2+ (reduced iron), rather than a deficiency. I have now found some references to Fe2+ toxicity, but no specific term. Could you have another look at the translation and see if you agree with my interpretation?
Thanks so much to all of you,
C.
