Summary

In two long-term liming experiments on a sandy-clay loam at Rothamsted and a loamy sand at Woburn the responses of potatoes in 1974 and oats in 1975 to cumulative dressings of superphosphate and potassium chloride applied since 1962 and magnesium sulphate applied in 1974 were measured at four pH levels within the range pH 4–pH 7.

Yields of both crops were similar over the whole pH range when standard rates of NPKMg fertilizers were given. Without added P and Mg, yields of potatoes were much smaller on the more acid soils, but without K, yields were larger. A similar pattern of yield responses to P and Mg fertilizers occurred with oats but there were no differences between the small responses to K additions over the whole pH range.

Analyses of potato leaves sampled at the 10% flowering stage showed differences related to the yield effects for K and Mg but not for P. Yield responses were associated with concentrations less than 4% K and 0·18% Mg in the dry matter of topmost fully mature leaves.

The differences in yield response caused by liming were not associated with differences in ‘available’ nutrients in the soils (determined using standard methods).
