§ Mr. Elystan Morgan
asked the Secretary of State for Wales what estimates have been made by his Department of the need for fertiliser on soils in Wales.
§ Mr. Peter Thomas
No overall assessment would be realistic because the need varies from farm to farm and from year to year. For example, much depends not only on the fertility of the soil, but also on factors such as the nature of the particular production programme for the land concerned and the climate before and during the growing season.
