Since the three reviewers agreed with the suggestion of accepting the paper after minor revision, I confirm this decision.

The authors revised the paper according to the reviewers' suggestions and I think that the paper can be published after minor revision. In particular, I suggest a few technical changes, which are annotated in the attached pdf file.

The paper can be published. I stress two points that could be possibly improved with very minor changes, without requiring any further examination of mine.

I wonder whether the caption of figure 2 could be changed, possibly as "Determination of soil tension for gravitally-driven flow rates corresponding to irrigation rates of 2 and 12 mm/h for two of the columns".

p<0.05 can be confused with p0.05, which is a completely different quantity. I read again section 2.7 and I understand that p<0.05 means that a correlation is considered to be significant if it leads to a confidence level of 95%. I suggest to clarify this and possibly to slightly change the notation.
