Report of the cooperative fertilizer and variety tests in Dalarne and Norr- 

 land, 1908, S. ItiiODiN {Mcddcl. Criil nihilist. F6rf<ok.^r. Joidhntksoiinudct, No. 

 16, pp. 115). — Reports are given of 77 fertilizer experiments with oats, barley, 

 oai hay, potatoes, mangels, grass land, soil inoculation, and nitragin, and of 

 111 variety tests with oats and oat hay, barky, peas, soiling crops, potatoes, and 

 mangels, as conducted in the Swedish counties. 



[Work at the Fiji- experiment stations], C. 11. Knowlks {lipt. Agr. Fiji, 

 1!)08, pp. 1-27). — This paper i-eports results of the work at tlie Nasinu and 

 Lautoka experiment stations, dealing with grain, fodder, forage, fiber, and mis- 

 cellaneous crops including various spices, coffee, cocoa, and rubber. Notes 

 are also given on insect pests and the results of manurial experiments on coco- 

 nut trees. 



Influence of autumn plowing on the humidity of the soil, K. G. Mankovskl 

 ( YkzIi. Ros.s. Scls'k. Klioz. (ihaz., 1908, Xo. 37; <ihs. in Zliiir. Opnitn. Agron. 

 (Riiss. Jour. E.rpt. Ldiidic), 10 {1909), Xo. 3, p. 379). — Observations on the 

 Poltava Experiment Field indicate that plowing in the fall not only does not 

 ])romote a better penetration into and retention by the soil of the winter precijii- 

 tations but, on the contrary, very frecpiently hinders ]ienetration. 



Fallow culture according- to data of the Poltava Experiment Field, K. G. 

 Mankovski (Selsk. Khoz. i Lgcsov., 1908, Dec; abs. in Zhnr. Opuitii. Agron. 

 {Russ. Jour. Expt. Landio.), 10 {1909), No. 3, pp. 38//-3S7').— This article re- 

 ports tests of black fallow and of early (April), middle (May), and late (June) 

 green fallow, on forest and clay soils overrun by weeds and in poor condition as 

 received from peasants. The crops used were rye and wheat. 



During the S-year period 1886-1893 the black fallow was not inferior to May 

 fallow with full manurial fertilization, but during the succeeding 8-year perioil 

 the yields on the black fallow failed greatly and became less than either the 

 manured or unmauured May fallow. Continuous forcing of the activity of the 

 soil by fallow cultivation of the same field in 3 course rotations, led to impov- 

 erishment of the content of humus, nitrogen, phosphoric acid, mineral sub- 

 stances soluble in hydrochloric acid, and fine earth. Early green fallow gave 

 better results than either middle or late green fallow, as shown by the average 

 yields for the 12-year period 189.5-1906. 



Grass and clover seed production and handling in Denmark, Great Britain 

 and Ireland, IIollmanx and Skalweit (Bcr. Land. u. Foratir. Anshmdc. 1909. 

 No. 20, pp. 52). — ^A general review of seed production and marketing in Den- 

 mark, Great Britain and Ireland is given, together with notes on the principal 

 grasses and clovers the seeds of which are of commercial importance in these 

 countries, and data in regai'd to plant breeding, purity, gernnnation. and other 

 tests, including an experiment in Denmark with superi)hosphate and Chile salt- 

 peter, in which 2.50 lbs. of 18 per cent superphosphate produced a net profit of 

 |'5.60 per acre greater than the unfertilized plat, while with a mixture of 2r)0 lbs. 

 of 18 per cent superphosphate and 100 lbs. of Chile saltpeter the increased net 

 profit was $14.05 per acre. The crop used in the test was cocksfoot (Dactylis 

 glomerata). 



The yearly production of grass and clover seed in Denmark is given as ap- 

 proximately 17,.500,000 lbs., of which 15,000.0(J0 lbs. is exported.
