I have a rusty old stock tank that holds about 350 gallons of water that I am about to start using to water pumpkins. Will the rust hurt the pumpkins??? You have to settle the argument...I say no and my husband says yes!

Thanks!

I don't think rust will be an issue as the water will be changed so often. And the extra iron might help (:0)..... Terry

Sounds like a non-issue to me. If you are low on iron it might make an improvement. If your iron level is fine it probably won't be enough to cause any problem.

Iron(III) oxide (rust)is insoluble in water and only really dissolves in strong acid. I imagine it is not going contribute to available Fe in the soil but I wonder if it might give a false positive on soil test reports. Interestingly rust does dissolve well in solutions of the chelating agents such as EDTA which is present in many soid additives.

an interesting fact rusty water will not affect your plants it will only make me feel better my grandmother actually uses it as a repellent for any Burling mammals.
