HC Deb 14 June 1972 vol 838 c336W
Mr. Deakins

asked the Minister of Agriculture, Fisheries and Food what estimate he has made of the amounts of inorganic fertiliser running off farm land into rivers in Great Britain.

Mr. Peter Mills

Monitoring is carried out by my Department and investigational work by the ARC. But it is not possible readily to identify the origin of inorganic chemicals in the run-off from agricultural land. Their presence can be due to many causes, not least the natural processes in the soil. There is nothing to suggest that in general the run-off of chemicals which there may be from agricultural land is hazardous.
