Summary

This dataset contains the annual grain and straw yields of the Woburn Continuous Wheat experiment, 1877-1926. Also grain %N for some plots and years. Details of the fertilizer, manure and lime treatments are also included. There was a parallel experiment at Woburn testing the same treatments on the yield of continuous spring barley. This experiment also mirrored the continuous winter wheat experiment on the silty clay loam soil at Broadbalk, Rothamsted, started in 1843. The soil at Woburn contained little free calcium carbonate, and soil pH was 6.1 in 1876. Consequently, where ammonium sulphate was applied (plots 2, 5 and 8) the soil soon became acidic and yields declined markedly within 20 years. These were the first experiments in the UK where lime was applied to try to correct soil acidity.

Methods

This experiment tested different fertilizer, manure and lime treatments on the yield of continuous winter wheat grown on a sandy loam soil at Woburn. Originally 11 plots (1-11), some were divided into sub-plots (a and b) from 1882, and into sub sub-plots (i and ii) from 1905, to test different treatments, mainly with and without lime. To allow comparison of the different treatments, yields are shown for all 50 years for each sub-plot.

Technical Information

Grain and straw yields at field moisture content, approximately 85%, though this was not recorded. Grain % N content measured in grain dried at 100 degrees C, assumed to be 100% dry matter. Grain %N not recorded for all plots. Harvest date not recorded.

Rothamsted relies on the integrity of users to ensure that datasets are used appropriately and Rothamsted Research receives suitable acknowledgment as being the originators of these data. Please review the Conditions of Use before downloading.

Individual plot yields are taken from Russell and Voelcker (1936) appendix tables. The treatment details were taken from Glendining 2022. This frictionless dataset of combined yield and treatment data was compiled by M Glendining and checked by S Perryman, May 2022.

In accordance with the Joint Code of Practice for Research at Rothamsted, data processing in e-RA follow rigorous standard operating procedures to ensure the quality and correctness of data collected in the field through to depositing in the e-RA database. To ensure quality control during data inputting, the data sets were typed on two separate occasions (double data entry). During the second typing (verification) the data values were compared with those typed on the earlier occasion, and any discrepancies were resolved before verification continued. This procedure also set out how to handle situations where the written records were illegible or ambiguous. This procedure avoided visual checking of data, which can be very inaccurate.
