Joint Oireachtas Committee on Agriculture, Food and the Marine

Nitrates Directive, Water Quality and Pollution: Discussion

Mr. Jack Nolan:

Slurry contains 9 units of nitrogen per 1,000 gallons and soiled water contains 4 units. Some people say that there is nothing in it, but there is a nutrient value in it. It is proposed that there would be four weeks' storage by the end of 2024, which can be granted aided if a farmer is compliant, and that soiled water would not be spread between the middle of November and the middle of January. The reasons are, as we discussed earlier, because there is very little growth at that time of year. If nutrients are applied through the application of soiled water, one will see the grass greening up because of the nitrogen contained in it. The logic behind it is to prevent, as much as is possible, nitrogen loss to water. None of the measures proposed on their own are a magic bullet or will solve water quality issues, but each of them deliver a little bit and when added up, we will get to where we want to be in order to meet our water quality targets.
