Extract

1. The paper describes ten consecutive field experiments carried out between 1952 and 1961 investigating the action of F.Y.M. on the yield of maincrop potatoes. In all experiments high basal dressings of PK fertilizer were used.

2. Soil moisture deficits were estimated from meteorological data and the maximum deficit (M.S.M.D.) in a particular season used as an index of the dryness of the growing season.
