It was said to me there is a problem here, cause there is no variance of the control and ulex treatment - it can be the nature of the data or it can be the assumptions to apply anova in these data were not achieved.

[Graph built with RAW DATA look the variance in first and second boxplots]

The data was log transformed and I think it looks ok in the diagnosis graphs, but maybe I'm not experienced enough to interpret the diagnosis graphs, so I'm asking for your help on this. Graphs are below. [Diagnosis over log transformed data - qqplot] [Diagnosis over log transformed data]

You maybe interested in look at the Phosphorus raw data to tell me the variance is related to the nature of the data, but what can I say about it so?
