HC Deb 11 June 1979 vol 968 c85W
Mr. Alton

asked the Minister of Agriculture, Fisheries and Food how much sulphur has been deposited on agricultural land over the past decade; and how much this has increased the acidity of agricultural land in the United Kingdom.

Mr. Wiggin

Reliable estimates of amounts of sulphur deposited on to agricultural land are not available. Current studies have not yet indicated any general change in soil acidity.
