81. Mrs. Slater
asked the Minister of Housing and Local Government and Minister for Welsh Affairs what co-ordination there is between his Department and the Minister of Agriculture, 115W Fisheries and Food regarding the use of crude retort-house gas liquor as a fertiliser.
§ Sir K. Joseph
My right hon. Friend and my right hon. Friend the Minister of Agriculture, Fisheries and Food keep in touch on this as on other matters of common interest. The use of gas liquor as a fertiliser has been growing in recent years, and my right hon. Friend welcomes the relief which this affords to sewage treatment works.
