HC Deb 13 May 1968 vol 764 c208W
Mr. Jopling

asked the Minister of Agriculture, Fisheries and Food what increase in fertiliser usage was envisaged by the National Plan.

Mr. Hoy

No precise production targets were set for agriculture under the Plan, but the industry estimated that expenditure on fertilisers would need to increase 20 per cent. over the period if production were to expand to the full extent technically feasible.
