The British Survey of Fertilizer Practice has its origins in surveys begun during wartime in 1942, conducted thereafter as the Survey of Fertilizer Practice for England and Wales. The survey was re-designed in 1969 as an annual survey to monitor trends in fertilizer use and the methodology was extended to Scotland in 1983. This nationally representative survey is based on the annual selection of a random stratified sample of farms in mainland Britain. The Survey is the principal source of estimates for fertilizer use in Great Britain and the data are widely used by the British fertilizer industry and by Government, who jointly fund the Survey. Data are also collected on lime and organic manure usage.
