Summary

The experiment tests the effects of different amounts of lime (and thus soil pH), P and K on the yields of a sequence of arable crops, on a sandy loam soil at Woburn 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 was a parallel experiment at Rothamsted Experimental Farm. This experiment was discontinued in 1997. The dataset contains plot and sub-plot yields for all plots and years, 1962-1996, details of all treatments applied (lime, P, K, Mg, Mn and S) and agronomic details (crop variety, sowing and harvest dates, basal fertilizer).

This dataset was partially funded by the BBSRC Institute Strategic Programme Soil to Nutrition (BBS/E/C/000I0310).

Methods

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.
