HC Deb 16 December 1949 vol 470 c371W
Mr. Baldwin

asked the Minister of Works if, instead of expending £660 per annum on artificial fertilisers for the gardens in the Royal parks, he will give instructions to have the leaves collected and turned into compost thus releasing 26 tons of artificial fertiliser and permit the enjoyment of the air in the parks unpolluted with the obnoxious smell of burning leaves.

Mr. Key

So far as the supply of labour permits, everything possible is done to collect suitable leaves for composting, but other fertilisers, such as bone-meal, are also required.
