There is a very close resemblance "between the effects of the 
<lifferent manures on the barley and on the wheat. Mineral 
manures alone gave no increase of crop ; whilst ammonia-salts 
alone, or nitrate of soda alone, gave a very considerable increase. 
As with the wheat, the ammonia-salts produced more effect than 
the nitrate, whether used alone or in conjunction with mineral 
manures ; and whether (with mineral manures) in quantity cor-
