RESULTS WITH BARLEY 



determined during the first six years of the experiment, when 

 both 200 Ibs. and 400 Ibs. of ammonia salts were employed 

 (Watts' Dictionary of Chemistry, Third Supplement, Barley, 

 p. 148). Multiplying the percentage of nitrogen in the 

 grain by the factor proposed by Osborne as proper for 

 barley grain, and the percentage of nitrogen in the straw by 

 the conventional factor, 6-25, we obtain the percentages of 

 albuminoids given in the following table : 



TABLE XVIII. 



PERCENTAGES OF ALBUMINOIDS IN THE DRY MATTER OF 



BARLEY GRAIN AND STRAW, VARIOUSLY MANURED, 



AVERAGE OF SlX YEARS, 1852-57. 



It will be seen that the smaller dressing of ammonia salts, 

 used with superphosphate and alkalies, has had very little 

 effect in increasing the percentage of albuminoids in the barley 

 grain, while as we have already learnt, it has greatly increased 

 the produce of grain per acre and much improved the weight 

 per bushel. With such manuring the general malting character 

 of the barley has rather improved than deteriorated. When 

 the larger dressing of ammonia salts is employed there is a 

 much greater increase in the percentage of albuminoids, the 

 weight per bushel falls somewhat, and the malting character 

 of the barley is deteriorated. When the ammonia salts were 

 used without superphosphate and alkalies the deterioration of 

 the malting qualities became still more marked.
