Is Iron Toxicity is Iron excess???
I almost made up my mind for this project.
All I have to do is to be more clear about iron excess on plant.
Should I change my topic from Leaf burn to Iron Toxicity? or are those two totally differnt things?

Iron excess is Iron toxicity.Iron toxicity can occur due to many causes.

hi christina

from what i understand i think that iron toxicity and leaf burn are different although they may be related some how because leaf burn is something that happens when a person sprays chemicals on a foliage on a hot day and the chemicals act like a magnifyer on the plant to burn it.

but anyways choose something that best fits you...those two topics are both valid whether you deal with iron or leaf burn...they are both great topics to research

i would suggest that you go with leafburn, as the introduction of chemicals or overfertilization would be easyer to test in a shorter amount of time than iron toxicity. as well the results may be easyer to observe.
