Summary

The experiment tests the effects of four different amounts of lime (creating a soil pH range for approximately 4.5 to 7.5) with and without fertilizer P, on the grain mineral composition of three arable crops. The site is a silty clay loam soil at Rothamsted Experimental Farm, from 1962-1996. The dataset contains grain mineral composition for 20 different minerals (mg/kg dry soil), for individual plots, measured in 1978, 1981 and 1995. It includes details of the lime and fertilizer treatments, and crop yield.

There was a parallel experiment on a sandy loam soil 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. For more details contact Dr SM Haefele.

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

Methods

Grain mineral composition was determined, in 2019 and 2020, on archived ground samples grown in 1978 (barley), 1981 (oats) and 1995 (wheat). Macro-nutrients (Ca, K, Mg, Na, P, S) and Al, Fe and Ti were determined by open tube digestion with HNO3/HClO4 and measured with ICP-OES. Micro-nutrients and trace elements (As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Se, and Zn) were determined with microwave digestion with HNO3/H2O2, then measured with ICP-MS.
