This season was considered unfavorable for wheat. The continuously
unmanured plot produced 14-3/4 bushels, and the plot receiving 14 tons
of barn yard manure, 25-3/4 bushels per acre nearly.

300 lbs. of ammonia-salts alone on plot 10_a_, gave 19-1/4 bushels per
acre, while the same quantity of ammonia, with superphosphate in
addition, gave, on plot 9_b_, 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 10_b_, 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 17_b_, nearly 29 bushe
