EXPERIMENT STATION. 



[Jan. 



It will be noted that the asparagus is the oiilv 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 remarkable difference in the 

 appearance 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 difference characterized 

 the ap})earaiice of the clover on the two salts. In the case of 

 rhubarb the proportion of leaf to stalk, as in previous years, 

 Avas 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 progress since 1890. It occu- 

 pies the south corn acre, which is divided into 4 jdots of one- 

 (piarter acre each. On two of these plots good barnyard 

 manure from well-fed dairy cows has been apidicnl 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 

 smaller applications of manure high-grade sulfate of potash at 

 the rate of IGO pounds per acre has 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 ])ractice has been to apply manure annually, but 

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

 b(^ done the newly seeded grass and clover would lodge badly, 

 the customary application has been witlilicld : but in all cases 

 if withheld from one plot it was of cmirse willilicld from all.
