Developed by the Department of Agriculture and Rural Development of Northern Ireland, the calculator is designed to help you manage the nitrogen loading limit of the Nitrates regulations.
The nitrogen loading limit for most farms is 170 kg N/ha and this is in effect a stocking rate limit.
By entering the numbers of livestock you have and the land area that you farm you can check if you are below the 170kg N/ha/year limit or if operating under derogation below the 250kg N/ha/year limit.
The Calculator is easy to use, available 24 hours per day, secure and confidential.
