Woburn Amounts of Straw

Experiment Code: W/CS/326
Experiment Site: Woburn
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 Rothamsted 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 experiment was discontinued after the 2017 harvest. No yields were recorded in 2016 and 2017.
Date Start: 1987
Date End: 2017
