Abstract
A THIRD and enlarged edition of Bulletin No. 22, “Practical Soil Sterilisation”, has been issued by the Ministry of Agriculture. As in former editions, the volume deals with the practical aspects of sterilising soil by means of heat and chemicals, both on a large scale in glasshouses and in small quantities for market garden and propagation work. The process of sterilising soil by steam is now widely practised, and the recent development of a new device, the ‘Hoddesdon’ pipe system, which overcomes many of the disadvantages of the older methods, called for a revised issue of the bulletin. The new system is composed of pipes laid in position separately and joined prior to turning on the steam, thus enabling a more efficient distribution of the heat than was possible with the tray, grid or spike methods, where small areas tended to remain untouched. In addition, the cost, namely, £160 per acre, compares favourably with other methods, and the labour is less arduous, so that from all points of view the new system can be recommended to the commercial grower with every confidence. All practical details are supplied in the bulletin, which may be obtained from H.M. Stationery Office or any bookseller, (Is. net).
