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, from 1962-1996. Mg, Mn and S were tested on split plots at different times. Target soil pH was 4.5, 5.5, 6.5 and 7.5. There is a parallel experiment at Woburn Experimental Farm. Since 1997 the experiment has been in grass.
Period 1 (1962-1980): four lime levels with and without fertilizer P and K. Magnesium was tested on split plots 1974-1978. Period 2 (1981-1996): four lime levels with four P levels. Manganese was tested on split plots 1987-1990; Sulphur was tested on split plots 1991-1996. 2 replicates.
