It will be seen that on all the plots the yield of grain is considerably lower than last year, with a greater growth of straw. You will notice that 10_b_, which last year gave, with ammonia-salts alone, 32¼ bushels, this year, with superphosphate, potash, soda, and sulphate of magnesia, gives less than 18 bushels, while the adjoining plot, dressed with ammonia, gives nearly 27 bushels. In other words, the ammonia alone gives 9 bushels per acre more than this large dressing of superphosphate, potash, etc. On the three plots, 8_a_, 8_b_ and 9_a_, a dressing of ammonia-salts alone gives in _each case_, a larger yield, both of grain and straw, than the 14 tons of barn-yard manure on plot 2. And recollect that this plot has now received 98 tons of manure in seven years. “That,” said the Doctor, “is certainly a very remarkable fact.” “It is so,” said the Deacon. “But what of it?” asked the Squire, “even the Professor, here, does not advise the use of ammonia-salts for wheat.”
