A fertilizer experiment with crude phosphate, F. W. Dafkkt {Zt-trhr. Lavdir. 

 Vcrt^vrhw. Orsti'rv., 4 {1901), Xo. 5, pp. 627-629). — Previous experiments by the author 

 (E. S. R., 12, i>. SSQ) showed that Algerian phosphate was quite effective as a souree 

 of phosphoric acid for summer barley and oats. The experiments here rej>orted 

 show that it is also very effective as a fertilizer for clover. 



Report of the agricultural chemical laboratory of the Ministry of Agri- 

 culture and Imperial Domains in St. Petersburg for 1898, P. S. Kossovicii 

 {!St. Peterslmrg: Department uf Agriculture, 1900, pp. 242; rev. in Selsk. Klioz. i Lyemv., 

 199 {1900), Oct., pp. 237, 238). — This report contains two articles which may be 

 mentioned here: (1) Availability for plants of the phosphoric acid of the Russian 

 phosphorites, and (2) ability of plants to utilize the phosphoric acid of phosphorites. 

 According to experiments reported, plants may be divided with regard to their 

 ability to avail themselves of the phosphoric acid of the phosphorites into -4 groui)s: 

 (1) Plants with high capacity — mustard, buckwheat, hemp, winter rye; (2) plants 

 with medium capacity — peas, barley, summer rye, beets; (3) plants with a low 

 capacity — potatoes, oats, vetches; and, lastly, (4) plants almost devoid of this capac- 

 ity — millet, flax, and clover. — p. firemax. 



Nitrate of soda and sulphate of ammonia, H. Bachmann {Filhling's Lambr. 

 Ztg., 50 {1901), Xo. 11, pp. 386, 387). — The results of oomi^arative tests of nitrate of 

 soda (8 cwt. per hectare) and sulphate of ammonia (6 cwt. per hectare) on potatoes, 

 fodder beets, and kohl-rabi are briefly reported. In these experiments the sulphate 

 of ammonia was apparently more effective than nitrate of soda. 



The regulation of the trade in nitrate of soda, M. Ullmann {Die Regelung des 

 Vn-L-rhrs mit Chili.mlpeter. Melle: F. E. Haag, 1901, pp. 25, pis. 4). — This pamphlet 

 includes an account of the action of a commission of the Society for the Protection 

 of the Chemical Industry in Germany regarding the regulation of trade in nitrate of 

 soda, a discussion of the l)asis of guarantees of purity, and a brief review of experi- 

 ments regarding the poisonous property of nitrate containing perchlorate. 



Experiments at the Bavarian moor culture station on the action of potash 

 fertilizers on upland moors, A. Baumanx ( Vrtljschr. Bayer. Landv: Rath., 6 

 1901), Xo. 1, pp. 20-35). — Comparative tests of kainit and concentrated and basic 

 potash salts are reported.

Fertilizing with lime refuse from gas works {Dent. Landu: Presse, 28 {1901), 

 No. 34, p. 297). — The handling and the fertilizing value of this material is Imefiy 

 discussed. Three weeks' exposure to the air is claimed to be sufficient to decompose 

 poisonous sulphur compounds.

 the Agricultural Society of Vienna in lower Austria during the year 1900 

 {Ztxclu: Landu-. Versurlnr. Ocytrrr., 4 {H'Ol), .Vo. 5, pp. 596-626, j)l. 1).—A detailed
