Is there alternative science to the science Dr. McGoff is quoting? In any argument, there are two sides. You can read an article today and think it is convincing and tomorrow you could read an article on the other side of the argument and it can be equally as convincing. I am not a scientist but for the purpose of conversation, my layman’s theory on it would be that the cow urinating on the grass is small volume frequently. I would imagine it would soak unless it is very free draining as opposed to slurry coming out in bulk. I would use the same argument for Dr. McGoff’s answer to Deputy Fitzmaurice with regard to the mixed species and the clover. You are spreading artificial fertiliser and putting a volume of nitrogen on the ground. If it comes a wet night, that is bound to be a bigger problem than the photosynthesis or whatever and the clover taking in the nitrogen in small consistent volumes to the root of the plant where there are other roots and it is being taken up. I could not believe that multispecies and clover would be considered a problem when it came to leakage.
