Woburn Long-term Liming Experiment
- Experiment Code: W/CS/10
- Experiment Site: Woburn
- Objectives: To study the effects of different amounts of lime (and thus soil pH), P and K on the yields of a sequence of arable crops. Mg, Mn and S treatments were also applied.
- Description: Yields of various crops were recorded from 1962-1996 and papers published (Bolton, 1971, 1977 a,b; McEwen et al, 1990; Holland et al, 2019). The experiment is now discontinued.
- Date Start: 1962
- Date End: 1996

Experimental Design
Description
- Four lime treatments with and without P and K (4 x 2 x 2 factorial with two replicates, 32 plots) within randomised blocks and with plot sizes of 6 m x 18 m. The experiment was fallow in 1969, 1979 and 1980. In 1962 columns of 4 plots were split for uninoculated v inoculated seed. In 1964 plots receiving both P and K were subdivided for a comparison of method of application, broadcast versus drilled. In 1974-1978 a comparison of with and without Magnesium was applied to the 64 sub-plots.

Site: Stackyard Field Section 3 - Woburn
- Experiment Site: Woburn
- Description: The site is an old arable site, which had not grown beans for many years. The soil was acidic and deficient in P and K. The intial pH ranged between 5.6 and 6.3. The experiment was started in 1962 and cropped until 1996. In 1997 the experiment was discontinued.
- Management: From 1962-1996 the site was managed according to conventional practices. In most years N fertilizer was applied to crops at a rate appropriate for the crop and site, and a range of conventional pesticides were used to control weeds, pests and diseases.
