102 BULLETIN OF THE BUSSEY INSTITUTION. 
The results of this first year’s trials are decidedly favorable in the 
case of the potassic manures. Sulphate of potash, for example (a 
pure article, commercially speaking), applied at the rate of 800 lbs. 
to the acre, gave 2,577 lbs., i. e. 43 bushels, of beans to the acre, or 
three times as many as were harvested from the unmanured land. 
Barley thus heavily dressed with sulphate of potash yielded at the rate 
of 1,650 lbs. or 34 bushels of grain to the acre, or more than twice as 
much as was got from the unmanured land. 
Some of the results obtained by the use of lime upon land that had 
been previously manured (Section A) are remarkable. In several in- 
stances the squares yielded barley at the rate of 2,850 lbs., or 59 
bushels to the acre.
