FERTILIZERS. 581 



"A number of miscellaneous jilants which have been grown on one or two previous 

 occasions have been rotestod iu order that the data in relation to them might be 

 increased to such an extent as to render the conchxsion drawn of greater value than 

 would otherwise be possible." 



The results are tabulated and lllustiated. Tlie folio wiug summary is 

 giveu : 



"The following vegetables have shown this season beneiit from liming, decreasing 

 In the following order: Ouious (Egyptian), celery, onions ("Barletta), pumpkins, 

 mangel-wurzels, muskmelons, carrots, table beets, dandelions, cabbages, kohl-rabi, 

 and tlat turnips. 



" Carrots and pumpkins, which showed an apparent injury from lime in 1894, have 

 given an increase upon the limed plats iu 189.5. It is possible that these two j^lauts 

 should be introduced into a rotation a year or two after the lime has been applied 

 in order to secure the be.st results, a point which can only be ascertained with cer- 

 tainty by further experiments. 



"The watermelon showed a decided injury from liming in 1894, which was even 

 more marked in 1895. In this particular the watermelon stands in marked coutrast 

 to the muskmelon, which was practically a failure both years except upon the limed 

 plats. 



"Alfalfa, like clover, has shown a decided beneiit from liming, while serradella 

 and blue lupiuo have, on the contrary, been injured thereby. The injury to the 

 lupiue has been observed in each of the 3 years of the experiment, though it was 

 greatest in 1894, immediately following the second a]iplication of lime. 



"Common sorrel has shown an injury from liming during both of the years in 

 which it has been grown, though the injury was greatest iu 1894, immediately follow- 

 ing the second application of lime. 



"The observations with the different grasses indicate that timothy, Kentucky 

 blue grass, awnlcss brome grass, and others may be benelited by lime iu varying 

 degrees, while the sweet vernal, soft grass, Rhode I.sland bent, and sheep's fescue 

 indicate less or no benefit from its use. These results with grasses, as has been 

 stated previously, are those obtained from the first season's growth, and can not 

 therefore be so conclusive or satisfactory as the results of succeeding seasons. It 

 appears probable, however, that the individuality of the grasses in respect to their 

 benefit or injury from liming may be as great as that of the individual members of 

 the leguminous, melon, and other families of plants." 



Experiments -with various kinds of barnyard manure alone 

 and compared -with nitrate of soda, sulphate of ammonia, and 

 urine, Maercker {Jahrh. Agr. Chem. Fer,9. Stat. Halle 1895, irp. 

 57-69 ; ahs. in Dent, landw. Presse, 23 {1890), JSTo. 98, p. 871, Jig. 1).—A 

 summary is given of pot experiments with 2 samples of deep stall sheep 

 manure and 4 samples of ordinary barnyard manure. The sheep manure 

 approached the ideal in composition ^ and compared very favorably with 

 sulphate of ammonia and nitrate of soda on oats. The barnyard 

 manures, on the other hand, were either without effect or lowered the 

 yield. It is suggested that this was due to the reduction of nitrates by 

 the organisms of the manure.-' 



Comparative action in granitic soils of different phosphatic fer- 

 tilizers on the cultivation of potatoes, G. Battanchon {Prog. Agr. 

 et Vlt., 20 {1890), Xo. :jo,pp. .v^-'AV).— Two mineral phosphates, Thomas 

 slag, precipitated phosphate, and superphosphate were tested on plats, 

 all of which had received a dressing of barnyard manure and a basal 



' Having 70 per cent of its nitrogen readily available, i. e., furnished mainly by urine.
