Highfield Bare Fallow

Local identifier
R/RS/1
Years operational
1959—
Description
In 1959 an area of permanent grass (since 1838, Lawes & Gilbert, 1885) adjacent to the Highfield Ley-Arable experiment at Rothamsted was ploughed, and has not grown a crop since. This is the Highfield Bare Fallow. Soil organic carbon (SOC) is measured periodically, and this has declined substantially since the area was first ploughed out of grass. Archived soil samples are available.

History
Permanent grass since 1838 (Lawes & Gilbert, 1885) adjacent to the Highfield Ley-Arable experiment at Rothamsted.
Management
Since 1959 the experiment is kept free of weeds by frequent cultivation, but herbicides are used occasionally, so inputs of carbon to the soil are negligible. The experiment is on a trapezoidal area of approximately 900 m2.
