Abstract
THE results of a detailed examination of the problem of nitrogen fixation were given in the comprehensive Final Report of the Nitrogen Products Committee of the Ministry of Munitions, published in 1920, and already noticed in these columns (vol. 104, pp. 533 and 569; vol. 105, p. 201). As the Ministry of Munitions is no longer in existence, the Department of Scientific and Industrial Research has arranged for the publication of the additional statistical information which has been accumulated since that time. This Supplementary Report has been drawn up by Dr. J. A. Harker, the director of the Nitrogen Research Laboratory under the Ministry of Munitions. It deals with the statistical aspect of the Chile nitrate industry, the saltpetre industry, the nitric acid industry, the ammonium sulphate industry, the synthetic ammonia industry, the Norwegian fixation industry, the cyanamide industry, the ammonia oxidation industry, and the fertiliser industry. It includes, in addition, a variety of miscellaneous statistics relating to the world's production of fixed nitrogen, national internal sources of fixed nitrogen, the world's fixation plants and power requirements, and the prices of nitrogen fertilisers in England and Germany. The whole concludes with a reference to the present position of nitrogen fixation in this country.
