Rothamsted Amounts of Straw
- Experiment Code: R/CS/326
- Experiment Site: Rothamsted
- Objectives: To study the effects of a range of amounts of straw incorporated into the soil on winter wheat.
- Date Start: 1987
- Date End: 2017
- Key Contacts: Margaret Glendining, (Data Manager), 0000-0002-6466-4629 ,
Description
- This experiment, along with the Woburn Amounts of Straw experiment provides a comparison of soil organic matter dynamics in contrasting soil types, at Rothamsted (a silty clay loam) and at Woburn (a sandy loam). The experiments have been used to study soil structure and earthworm activity. The findings at Rothamsted can be compared with those from section 0 on Broadbalk where straw is also incorporated. The experiment was discontinued after the 2017 harvest. No yields were recorded in 2016 and 2017.
Funding
- The e-RA database, including the published datasets generated from it, is part of the Rothamsted Long-Term Experiments - National Bioscience Research Infrastructure (RLTE-NBRI) , which also includes the Long-Term Experiments, the Sample Archive and Rothamsted's environmental monitoring activities including the weather stations and its role in the UK Environmental Change Network.
- The RLTE-NBRI is supported by the Lawes Agricultural Trust and the Biotechnology and Biological Sciences Research Council (Grants BBS/E/C/00005189 (2012-2017); BBS/E/C/000J0300 (2017-2022); BBS/E/RH/23NB0007 (2023-2028)).
