Abstract
THE increased demand for fresh vegetables has stimulated the grower‘s interest in new or improved methods of intensive cultivation. There remains, however, the difficulty of providing him with the latest information in an accessible form, and three illustrated bulletins issued by the Ministry of Agriculture (London: H.M. Stationery Office) on different aspects of the subject will do much to meet this need. "Irrigation" (Bull. No. 138. 1s. 6d. net) is entirely new. In it natural water supplies of all types are discussed, and the various methods of augmenting them by means of spray or soil irrigation described. Such artificial systems inevitably entail heavy expenditure, but it is considered that in some circumstances the results may fully justify it. "Crop Production in Frames and Cloches" (Bull. No. 65. 2s. 6d. net) has been completely rewritten. It provides a wealth of practical information, though stressing the fact that a thorough understanding of soils, varieties, ventilation, etc., is needed before success in this specialized line can be expected. "Practical Soil Sterilization" (Bull. No. 22. 1s. 3d. net) appears in a revised form. Large-scale methods employing both steam and chemicals are described for use in glasshouses, but instructions for dealing with small quantities of soil needed for propagation purposes or growing plants in pots are also included.
