Rothamsted Amounts of Straw

Local identifier
R/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 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.

History
Winter wheat was grown for the 3 years prior to the experiment starting
Soil type
luvisol
Soil description
Moderately well-drained flinty silty clay loam of the Batcombe and related series.
Climatic type
temperate oceanic climate

Design period: (1987—2017)

Design Type
Randomized complete block design
Description
Plots measure 40m2. 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)
