A test of nine phosijhates with different plants, II. J. Wheeler and G. E. 

 Adams (Rhode L'iland tSia. liul. llJj, pp. 113-131). — The experiments reported 

 in this hnlletin were begun in 1894 and have been pai'tly reported upon in a 

 previous hnlletin (E. S. R., 11, p. 042). 



Tlie ex]>eriiiients were made on limed and nnlimed series of plats {f^ acre), 

 which from 1804 up to the date of the experiments here reported had at differ- 

 ent times (1804, 18!)r), 189!)) received applications of dissolved boueblack, dis- 

 solved bone, acid phosphate, doultle superphosphate, tloats, fine-ground bone, 

 basic slag, and raw and roasted redondite, aggregating in the majority of cases 

 98..") lbs. of phosphoric acid per plat, or at the rate of 7.38.0 lbs. per acre. The 

 bulletin reports experiments on these plats with corn in 1900 and with a large 

 variety of other crops, including potatoes, barnyard grass (Panicum crus-galli), 

 oats, millet, soy beans, Adzuki beans, peas, squashes, turnips, cabbage, crimson 

 clover, and beets, in 1901. In every case the phosphates were used in connej- 

 tiou with a liberal basal fertilizer consisting of nitrate of soda and potash salts. 



In the case of corn ali the phosphates were as a rule more etfective on limed 

 than on nnlimed soil. Raw redondite was mu(4i less effective than roasted on 

 limed soils, while the two were of about equal etHciency on nnlimed soil. Floats 

 gave good results in these experiments, although the material was very ineffi- 

 cient on corn the first year it was applied. The results with double snpei'phos- 

 phate showed very low etticiency on nnlimed soils, and dissolved boneblac(v 

 gave " exceptionally poor residts," which it is suggested were possibly due to 

 the effect of drought, which was especially severe on the plats on which this 

 materi;il was used. 



'■ With the pea, oat, sununer squash, crimson clover, .Tapanese millet (on 

 the nnlimed land), golden millet, white-podded Adzuki bean, soy bean, and 

 Jiotato (on the nnlimed land) tloats gave very good results; but with the flat 

 turnii), table beet, and cabbage they were relatively very inefficient, notwith- 

 standing that much more pliosphorlc acid had been applied in the tloats than 

 in any other of the phosphates. 



" In the case of the pea, oat, summer s(piasli, crimson clover, Japanese millet, 

 golden millet, calibage, soy bean, and potato the yields were less on the limed 

 soil with than without the raw redondite. With but one or two exceptions the 

 yields were raised somewhat by its use on the nnlimed land." 



Liming exerted a marked influence in increasing the efficiency of roasted
