326 EXPERIMENT STATION EECORD. 



The average losses of the manure in weight, organic matter, total nitrogen, and 

 aunnonia during 3 to 3^ months were as follows : For common manure, loss in 

 weight 25.9 per cent, organic matter 26.3, total nitrogen 16.5, and ammonia 40.7. 

 For the limed manure (the lime being applied at the rate of 1.2 kg. per head 

 daily) : Loss in weight 22.3 per cent, organic matter 22.2, total nitrogen 16.9, 

 and ammonia 41.6. The results of the field trials showed that, in the case of all 

 the crops experimented with, the limed and the common manure possessed a 

 similar fertilizer effect, thus indicating that these crops are able to appropriate 

 similar amounts of nitrogen fi'om both kinds of manure when this is well cared 

 for and handled in a similar way. — r. w. woll. 



Does didyniium chlorid, a new disinfectant and preservative material, 

 injuriously affect plant growth? O. Bottcher (Deut. Landw. Pressc, 32 {1905), 

 'No. 90, PI). 752, 753; ahs. in Cciifhl Agr. Chew., 35 (1906), No. 7, pp. 451, 1,52).— 

 Experiments are reported which indicate that this material, which is now being 

 put on the market in Germany at prices which permit of its use as a disinfectant 

 and preservative, is an effective preservative of manure and, in amounts neces- 

 sary for this purpose, has no injurious effect upon plants. 



The relation between the care of liquid manure and its content of valuable 

 fertilizing constituents, A. Stutzer and P. Yageler {FiUiUng's Landw. Ztg., 

 55 (1906), No. 10. pp. 33S-3ff8). — Analyses of a large number of samples of 

 liquid manure produced under a variety of conditions of care and management 

 are reported, showing wide variations in composition with different methods of 

 preparation and handlini,'. 



Phosphates in New Zealand, B. C. Aston (Neio Zeal. Dept. Agr., Clicm. Div. 

 Bid. 1, pp. 10, pis. li, figs. Jf). — The deposits of phosphate which have already 

 been discovered and exploited in New Zealand are briefly described and the terms 

 of a bonus offered to encourage further discovery of phosphates in the island 

 are explained. One of the most important recent discoveries of phosphates is 

 that occurring in limestone pockets near Clarendon, Otago. 



" New Zealand mineral phosphate, which has hitherto been found in workable 

 quantities only at Milburn and Clarendon, Otago, has a dirty yellowish-white or 

 light-gray color. Some specimens exhibit a decided pink tinge in patches. It 

 is usually amorphous (non-crystalline), but thin veins of crystalline apatite 

 have been found at Clarendon. . . . Since the discovery of phosphate at Claren- 

 don some 15,000 tons of the fertilizer have been quarried, ground, and put on the 

 market." 



Phosphates in Nantes, L. Goi.dschmidt {Daily Consular and Trade Rpts. 

 [V. »S'.], 1906, No. 2636. pp. 5, 6). — In connection with statistics of importation 

 of phosphates into Nantes attention is called to the fact that formerly phos- 

 phates of high grade were imported into this city from Mona Island on the 

 east coast of Porto Rico, and while the exploitation of these deposits ceased 

 after a relatively short period it is believed that they may be worked with 

 advantage. 



The action of difficultly soluble phosphates on rye by means of lupines, 

 A. Mayer {Deut. Landw. Presse, 33 {1906), No. 52, pp. 1,33, //34).— Field ex- 

 periments are reported which show that insoluble phosphates applied to a pre- 

 vious crop of lupines gave better results at less cost in case of the following 

 ci'op of rye than superphosphate. 



The selection and use of fertilizers, W. P. Brooks {Farming, 2 {1906), No. 

 2, pp. 50, 51). — This article is based on the "better farming" talks delivered 

 on the special trains recently run through New Eugland, and outlines briefly 

 the principles which should guide in the purchase and use of fertilizei's. It 

 advocates the purchase of high-grade fertilizers especially adajjted to the soil
