Highfield Bare Fallow Experiment

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. It is kept free of weeds by frequent cultivation, but herbicides are used occasionally, so inputs of carbon to the soil are negligible. Soil organic matter (SOM) is measured periodically, and this has declined substantially since the area was...

Highfield Ley Arable Experiment

Starting in 1948, four blocks of four plots testing the effects of permanent grass, rotational grass, arable and bare fallow, were established on a long-term grassland site (>100 years). It provides a contrasting comparisons with the Fosters Ley-arable experiment where similar treatments were established on a long-term arable site and the Woburn Ley-arable experiment. Many archived samples and data are available.In 2008 two plots within each block were used to establish the Highfield Conversion Experiment.

Highfield Conversion Experiment

In 2008 two plots (continuous grass and arable) within each block of the Highfield Ley Arable experiment were split to establish grass, arable and bare-fallow treatments within each. Adjacent long-term bare-fallow areas were also included in the experiment. It is the only site at Rothamsted available for studying the effects of converting long-term grass to arable and bare-fallow treatments, on SOC, fertility, soil resilience and recovery. Soil samples are taken regularly and yields are taken...
