acre. This yielded 37.5 bushels per acre.
Section four contained q acres and
had 500 pounds of bone dust drilled in
with the wheat, costing $5.16 per acre.
This yielded 37.7 bushels per acre.
Section five contained 200 acres, and
had 500 pounds of ground lime stone
drilled in with the wheat, costing 81. 20
per acre. This yielded 35.7 bushels per
acre.
Section six contained 1888 acres, and
had little Stacked lime scattered over
II, intended TO make it equal in fertility
to the other sections before they were
icrtlized. This yielded l4.3 bushels
per acre.
All the above quantities are thresher's
measure, and, as the wheat weighs Gj
pounds to the bushel, the actual guam
tity will be from 10 to ID per cent. more
Assuming that the average of the field
without fertilizers would have been 20
bushels per acre, (which is 81 bushels
per acre more than the yield Of the
portion not fertilizedl, the profit from
the use Of fertilizers lcalling the wheat
worth 5 per bushel) is as follows
