§ Mr. Saltasked the Minister of Supply to what extent the shortage of potash for agricultural purposes in this country is now being obtained from industrial waste products; and whether any steps are being taken by his Department to encourage such processes.
§ Mr. PeatIndustrial waste products, mainly flue dust, provide only a small proportion of the supplies of potash for agricultural purposes. Full consideration led to the conclusion that the erection of plant for the extraction of the potash would not be justified, but flue dust may be purchased by farmers without restriction and in addition to their normal potash ration.
