§ Mr. Geraint Howells
asked the Minister of Agriculture, Fisheries and Food how many tons of basic slag were used by farmers in England in 1975; and what were the corresponding figures for the previous five years.
§ Mr. Strang
The information is not available in the form requested. However, whilst the fertiliser subsidy was operative information on the deliveries of subsidised basic slag—including potassic basic slag—was kept on a regular basis.
Figures for England for the last five years of the subsidy are as follows:
Crop Years (June-May) Product Tonnages 1969–70 378,727 1970–71 408,015 1971–72 371,560 1972–73 340,988 1973–74 232,327
Although these figures relate to deliveries it is probable that they give a good indication of the tonnages of basic slag used for the years given.
