This season was considered unfavorable for wheat. The continuously unmanured plot produced 14¾ bushels, and the plot receiving 14 tons of barn yard manure, 25¾ bushels per acre nearly.

300 lbs. of ammonia-salts alone on plot 10a, gave 19¼ bushels per acre, while the same quantity of ammonia, with superphosphate in addition, gave, on plot 9b, 25 bushels per acre.

The addition to the above manures of 300 lbs. of potash, 200 lbs. soda, and 100 lbs. sulphate of magnesia, on plot 10b, gave precisely the same yield per acre as the ammonia and the superphosphate alone. The potash, soda, and magnesia, therefore, did no good.

400 lbs. of ammonia-salts, with superphosphate, potash, etc., gave, on plot 17b, nearly 29 bushels per acre, or 3½ bushels more than the plot which has now received 70 tons of barn-yard manure in five successive years.

“I see that, on plot 0,” said the Deacon, “one ton of superphosphate was used per acre, and it gave only half a bushel per acre more than 350 lbs. on 9a.”

“This proves,” said I, “that an excessive dose of superphosphate will do no harm. I am not sure that 100 lbs. of a good superphosphate drilled in with the seed, would not have done as much good as a ton per acre.”

“You say,” remarked the Deacon, “that the season was unfavorable for wheat. And yet the no-manure plot produced nearly 15 bushels of wheat per acre.”
