Dataset: Rothamsted long-term liming experiment crop yield 1962-1996

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 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. 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 date, basal fertilizer).

There was a parallel experiment at Woburn Experimental Farm. This experiment was under grass from 1997-2019 and no treatments were applied. In April 2019 the experiment was revived, and is currently being used to investigate the effect of different lime, P and Zn treatments on macro and micro nutrient uptake of wheat varieties.

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