I recommend major revisions based on the reviewer's comments and the author's reply to those.

Dear Dr. McCormack and co-authors,
After reading your revised text and your response to the comments I can conclude that the reviewer's suggestions helped you to improve the paper considerably. I do not think a second review round is necessary.

I am sending you a annotated version of your revision and ask you to consider the minor edits that I suggest. In my comments there are two questions of a scientific nature:
Can you dig up any information about the nutrient output of the abattoir (possibly through its permit?)
As P in soils is strongly adsorbed by iron oxides, but some of your turloughs have an anoxic environment, do you believe such turloughs can act as sinks for P?

I would greatly appreciate it if you could take these questions into consideration as well.

Yours sincerely,

Gerrit de Rooij
