HC Deb 20 March 1979 vol 964 c543W
Mr. Skeet

asked the Minister of Agriculture, Fisheries and Food whether the efficient operation of fertilisers is affected by acidity pH of the soil; and whether he will seek to encourage the use of lime in appropriate areas to maximise the benefits of fertilisers.

Mr. Strang

Yes. The efficacy of fertilisers is affected by soil pH. My Department's agricultural development and advisory service is very conscious of the need to maintain correct soil pH values and hence the efficient use of fertilisers appropriate to the farming system, and its advice is regularly directed to this end.
