This paper describes six field experiments started during 1843-77. All, with various modifications, still continue and results for various periods between 1843 and 1975 are given. Originally the experiments investigated the nutrient requirements of wheat, barley and root crops, each crop grown in monoculture. Yields on unmanured and farmyard manure treated soils were measured and compared with those given by N P K Na Mg Si supplied in inorganic compounds and tested singly and in various combinations. These experiments soon demonstrated that fertilisers could give the same yields as farmyard manure and showed the relative importance of N, and K for the various crops.
