History
The experiment site had been cropped to a fallow-wheat rotation with minimal fertilizer additions since 1922.
Soil description
The soil is a Swinton loam, an Orthic Brown Chernozem (Canada Soil Classification), (Aridic Haploboroll, U.S. Soil Classification).

Design Type
Randomized complete block design
Description
N and P are applied based on the general recommendation for the crop and soil zone. Application of N and P for specific rotations is indicated in the rotation names below in parentheses with N and P. Rotations 6 and 7 ended in 1984 and were replaced by rotation 13. In 2006 rotation 13 plots were split and replaced by rotations 20 and 21. In 1979 rotations 9 and 10 were replaced by rotation 19.
Design description
The experiment compares 12 different rotation systems and is fully phased across 27 plots. Plots measure 10.5 x 40m.
