Woburn Amounts of Straw

Local identifier
W/CS/326
Years operational
1987—2017
Objective
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.

Design Type
Randomized complete block design
Description
Plots were 3m x 14.5m. Soil was sampled from all treatments after 7, 11 and 22 years of contrasting straw treatments
Design description
Wheat straw was incorporated annually at a rate of none, once, twice, and four times the yield of straw the previous year (approximately 0, 5, 10 and 20 t/ha)
