- 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.
- 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.
- Date Start: 1987
- Date End:
2017
