Experiment | Code | Purpose | Started |
---|---|---|---|
Saxmundham Rotation 1 | S/RN/1 | Since 1965, to observe crop responses to P and K and their interactions with N, particularly with high rates of N applied to high yielding wheat cultivars for bread-making quality. From 1899-1964 to test combinations of N, P, K and organic manures on a typical four-course arable rotation. | 1899 - 2010 |
Saxmundham Rotation 2 | S/RN/2 | Since 1965, to look at the response of various crops to fresh and residual soil P, and the decline in plant-available P when P fertilizer was no longer applied. From 1899 to 1964 to look at how limited amounts of FYM, sodium nitrate and superphosphate could best be used over a typical four-course arable rotation. | 1899 - 2010 |
