Design period: (1969—)
- Design Type
- Randomized complete block design
- Description
- The experiment site has contrasting clay and loam field areas. In 1993 and 2001 severe weather prevented sowing of winter wheat and spring wheat was sown instead.
- Design description
- The clay field area has 3 replicates and the loamy field area has 4 replicates
- Number of replicates
- 4

1969—2006Deep non-inversion tillage to 25-30 cm depth.shallow non-inversion tillage (10-15 cm depth)
1969—Shallow non-inversion tillage to 10-15 cm depth.minimum tillage (5-10 cm depth)
1969—Minimum tillage to 5-10 cm depthno-till
2007—Non tillage. This treatment replaced the deep non-inversion tillage factor level in 2007. The plots were last tilled in autumn 2006.
