Spanish term

ferrosis

Spanish to English Science Botany Plant health
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.

Thanks,

OK Done. Thanks, Chris.
Chris Ellison (asker) Jul 16, 2014:
Closing question Charles, if you want to propose iron toxicity, I will give you the points for all your hard work. Otherwise I will just close and gloss it. C.
Erwin S. Fernandez Jul 16, 2014:
Yes Rereading it made me agree. Iron toxicity fits the bill.
Charles Davis Jul 16, 2014:
Agreed The excess iron is the cause; the iron toxicity is the effect.
Chris Ellison (asker) Jul 16, 2014:
Gleysols OK, so as this about gleysols which have high levels of Fe2+, I think deficiencies cannot apply. Whether or not the original Spanish is actually correct we are not sure about, and the only term we have come up with as a possibility is "iron toxicity". For me, Erwin's suggestion of "excess iron", although descriptive, doesn't quite fit in the context.

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

OTOH The yellowing could be consistent with iron toxicity: on the page I've just cited, it says chlorosis of the leaves is common with manganese and iron toxicity. Chlorosis is simply not enough chlorophyll, and that means pale leaves, yellow or white. So I'd say toxicity here is more likely than not, given that "ferrosis" seems to be a rather informal term, actually, so we can't really rely on it always meaning deficiency.
Charles Davis Jul 16, 2014:
Deficiency/toxicity Generally speaking, when referring to nutrient disorders too little is called a deficiency and too much is called a toxicity. See here:
https://www.apsnet.org/publications/apsnetfeatures/Pages/Nut...

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.
Charles Davis Jul 16, 2014:
As for the term for too much iron, if that's the meaning, I think "iron toxicity" is it. Here's a page about it:
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.
Charles Davis Jul 16, 2014:
@ Chris Well, I must admit you seem to have a point. It is weird, though.

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.
Chris Ellison (asker) Jul 16, 2014:
Too much iron Hi everyone,
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.

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.

iron excess

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!

As mentioned in the discussion, in this particular case it seems to be a disorder caused by an excessive uptake of iron, and I think the term for that is
iron toxicity.

Hi, thanks for answering. :o) I've left a note in the discussion and was wondering if you could let me know what you think. :o) Cheers, C.
