Mr. Wootton-Davies

asked the Minister of Agriculture if he will institute a large-scale scientific inquiry as to the relative value of the different means of adding to land fertilisation.

Mr. Hudson

Investigations on different aspects of this subject are constantly in progress and the need for extending them is continually under review by the Ministry in conjunction with the Agricultural Research Council.
