 applying fertilizers, keeping up soil fertility, why green manures benefit the 

 soil, when and how to use green manures, making and caring for stable manures, 

 how and when to apply stable manure, and the profitable use of lime. 



An appendix gives data on plant food in typical soils, what crops take from 

 the soil, fertilizing materials in feeding stuffs, analyses of fertilizing materials, 

 value of manure produced by live stock, composition of farm manures, and ten 

 sample mixtures that farmers can make.

The nitrate of soda industry of Chile, Maizi£res {Engrais, 25 {1910), Nos. 

 48, pp. 1330-1333, dgms. 5; 49, pp. 1357-1359, clgms. 2; 50, pp. 1385-1381; 52, 

 pp. 1440-lJiJi3, dgm. 1). — This is a review of production and consumption of 

 Chilean nitrate and a discussion of the present status and future outlook of the 

 industry, based upon a report of the European representative of the Chilean 

 government, which to a large extent is a plea for the reestablishment of the 

 Nitrate Syndicate in Chile. 



Outlook of Chilean nitrate business, A. A. Winslow (Daily Cons, and Trade 

 Rpts. [U. -S.], 13 (1910), No. 127, p. 817).— It is stated that the outlook for this 

 industry seems good notwithstanding the low prices and the establishment of 

 a number of new nitrate worlds. Data are given which show that the output 

 and consumption in 1910 were much greater than in 1909. It is also shown 

 that the consumption of nitrate in the United States has increased rapidly in 

 recent years. 



Nitrate industry of Chile, H. P. Fletcher (Daily Cons, and Trade Rpts. 

 [U. 8.], 14 (1911), No. 7, p. i09).— Upon the basis of a report of the bureau of 

 manufactures of Chile it is stated that the estimated capacity of the nitrate 

 fields of that country is 242,150,000 tons. The exports amounted, to 2.319,571 

 tons in 1909, of which the United States took 503,889 tons. The estimated con- 

 sumption of nitrate in the United States in 1910 was 639,949 tons. 



[Production, exportation, and consumption of Chilean nitrate, 1910], E. 

 Fisher (Asoc. 8al. Propaganda, Circ. Trimcst. 54, 1911, p. III). — The total 

 production for 1910, according to the official statement of the Nitrate of Soda 

 Propaganda, is given as about 2,717,316 tons, an increase of 390,670 tons over 

 the production for 1909. The exportation was 2,574,613 tons, an increase of 

 221,518 tons over 1909. The consumption was 2,600,747 tons, an increase of 

 345,472 tons over 1909. 



Annual reports on nitrate of soda (Mark Lane Express, 105 (1911), No. 4137, 

 p. 37). — From reports of several large dealers in nitrate of soda it is esti- 

 mated that the total consumption of nitrate of soda in 1910 was 2,250,000 long 

 tons, of which 1,531.000 tons went to the Continent of Europe, 120,000 tons to 

 the United Kingdom, and 510,000 tons to the United States. The total con- 

 sumption in 1909 was 1.938,000 tons, of which the Continent of Europe used 

 1,354,000 tons, the United Kingdom 111,000 tons, and the United States 407,000 

 tons.
