EXl^ERIMENT STATION. 



[Jan. 



It will 1h! noted that the asparagus is the only crop which 

 gives a larger yield on the muriate, and that the superiority of 

 the sulfate is quite marked in the case of each of the others. 



There was a characteristic and remarkal)le diilereiice in the 

 ai)pearance of the alfalfa on the two salts throughout the entire 

 season, that on the sulfate being of a richer, darker green and 

 far more vigorous growth. A similar ditferencG characterized 

 the appearance of the clover on the two salts. In the case of 

 rhubarb the ])roportion of leaf to stalk, as in previous years, 

 was considerably greater on the sulfate than on the muriate. 

 This appears to be a highly characteristic effect, and is one for 

 which at present we are unable to offer an explanation. 



III. Manure alone compared with Manure and Sulfate 



OF Potash. 



This experiment has been in i)rogivss since 1800. It occu- 

 pies the south corn acre, which is divided into 4 ])lots of one- 

 (]uarter acre each. On two of these i)lots good barnyard 

 manure from well-fed dairy cows has been applied at the rate 

 of () cords per acre. On the other two plots similar manure has 

 been applied, at first at the rate of 3 cords per acre, but since 

 1895 at the rate of 4 cords per acre, and together with these 

 .^mailer applications of manure high-grade sulfate of potanh at 

 the rate of 160 pounds per acre lias been applied. The object 

 in view is to determine the crop-producing capacity of the 

 smaller amount of manure combined with sulfate of potash as 

 compared with that of the larger application of manure. 



The general practice has been to apply manure annually, but 

 in a number of instances, wdien it was feared that if this should 

 be done the newly seeded grass and clover would lodge badly, 

 the customary application has been withheld ; but in all cases 

 if withheld from one plot it was of course withheld from all.
