Q — ,·   winter-killing 0n this pl0t, due t0 its level situati0n, as sug·
g. ‘ gested by Mr. Austin. The yield 0n the unfertilized plot N0-
i 10 is higher than was t0 be expected, judging by pl0ts 1 and 5
_ and by pl0ts 11 and 12, which sh0uld have sh0wn m0re c0n-
3 trast with the unfertilized pl0t. Pl0t N0. 6, which preduced
t the largest yield, did n0t give any pr0f`1t 0n the m0ney
expended fer the fertilizer because 0f the great c0st 0f the nitrate
. 0f s0da. If the nitregen had been supplied in a m0re ec0n0m-
ical way, perhaps, by a cr0p 0f cl0ver 0r by barnyard manure, it
1 is quite likely that this pl0t w0uld have given the largest
, prefit, as well as the largest yield. It must be
remembered, h0wever, that the price 0f wheat has
i much t0 d0 with this calculation. If the wheat were w0rth $1.00
per bushel, the largest prefit w0uld c0me fr0m pl0t 6, being
ab0ut 40c 1n0re per acre than plot 3, where 0nly acid ph0s—
phate was used.
  The f0ll0wing described experiment was made by the late
Q Mr. J. C. Bingham, 0f Russell, Greenup Ceunty, Ky., after the
same plan as the 0ne already described, and was reperted by
Mr. XV. T. Bingham.
