Broadbalk Wheat Experiment, Soil Organic Matter Network (SOMNET), U.K.
Entry ID: IACR.Broadbalk

Abstract: This experiment began in 1843. The site was possibly farmed since
Roman times (i.e at least 1500 years). Map of 1623 shows field in
arable use. 1839-1843 arable crops: turnips, barley, peas, wheat,
oats. The soil is Clay-with-flint overlying chalk; see Avery & Catt,
The Soil at Rothamsted (see reference list) for full details.

The average climatic conditions at the experimental site are: Minimum
