256 REPORT OF THE FARM SUPERINTENDENT OF THE 
Muck vs. MANURE ON B15 anp 16. 
These two plats were differently fertilized in 1888 for a com- 
parative trial of muck versus manure, phosphoric acid and potash 
being added to the one on which muck was applied to equal the 
. calculated difference between those elements in the muck and 
manure. 
This season, instead of making any calculation to supply ash — 
elements, one cord of muck was plowed in on B15 and one cord 
of good stable manure on plat 16. The yields from these two ~ 
plats, shown in the above table, page 235, is in favor of that on 
which the muck was applied by nearly two bushels of merchant- 
able tubers, and of one bushel and twenty-three pounds on the 
total crop of sound tubers.

FERTILIZER EXPERIMENT WITH CORN. 
This is a continuation of the trial begun last year to test the 
relative value of the various fertilizing elements for corn, on the 
same ground continuously, for several years. The comparison is 
extended to the barn-yard manure and to green manuring, so far 
as a crop of rye grown after the ripe corn comes off in the fall, 
‘and before the spring plowing the following season, will allow. 
This season the muck and manure were drawn out and spread 
March twenty-fifth. The plats were plowed May tenth and — 
eleventh and the furrows harrowed down soon after. They were 
harrowed, marked and planted on the fifteenth, and rolled with a 
heavy roller on the sixteenth. The fertilizers were sown on the © 
twenty-first, with exception of manure and muck noted above, 
and green rye, a very light stand of which was plowed in on the 
tenth.
