AB  - The experiment tests the effects of different amounts of lime (and thus soil pH), P and K on a sequence of arable crops, on a silty clay loam soil at Rothamsted Experimental Farm, Harpenden, from 1962-1996. Archived topsoil samples from six years between 1964 and 1989  were re-analysed in 2019 for a range of soil exchangeable cations, by extraction with ammonium nitrate (NH<sub>4</sub>NO<sub>3</sub>). There was a parallel experiment at Woburn Experimental Farm.
