This dataset consists of the soil organic carbon (SOC), nitrogen (N), and soil weight, of individual plots of the Park Grass experiment, 1876-2023, and estimated values for when the experiment began in 1856. SOC and N were measured six times between 1876 and 2023. Soil weight was measured in 1876, 1959 and 2011/12. Data is given for the 0-23 cm soil depth. Not all plots were sampled on each occasion. Also included are details of the fertilizer and lime treatments applied.
<b>Estimated starting values</b> for when the experiment began in 1856, before the fertilizer and lime treatments were started were 3.1% SOC and 0.26% N.
On some plots, given ammonium salts but no lime, the soil became highly acidified and mats of undecomposed plant material have built up. These are indicated in the dataset.
These soil data are discussed in Poulton et al. (2026).
