Extract

1. In 1960 a 'reference plot' experiment was begun on Stackyard field at Woburn, where arable crops had grown for many years. The soil contained very little N or HCl-soluble K and little HC1-soluble P; it was acid, but was limed before and during the experiment to a pH at or near 7.0. Very small plots (0-00145 acre) were used.
