The British Survey of Fertiliser Practice is an annual nationally representative survey based on the selection each year of a sample of farms from mainland Britain. The main purpose of the survey is to estimate average application rates of nitrogen, phosphate and potash used for agricultural crops and grassland.

The survey is sponsored by the Department for Environment, Food & Rural Affairs and the Scottish Government, Rural and Environment Research and Analysis Directorate.
