THE EXPERIMENT STATION 89 



Plat IV 600 Ibs. ground bone and 200 Ibs. muriate 



of potash per acre, 



Plat V 600 Ibs. ground bone and 400 Ibs. double 

 sulphate of potash-magnesia per 

 acre. 



The following crops were grown during the several 

 years: barley, oats, dent corn, vetch and oats, Scotch 

 tares, soy beans, Canada peas, and oats. Several crops 

 were planted as a part of the same plat in each year, 

 the conditions on all of the plats being uniform. 



As a result of these observations, the following gen- 

 eral deductions were drawn: 



(1) In 1890 the effect of bone and different forms of 

 potash compared very well with stable manure, as did 

 also Canada ashes. Part of this favourable effect Goess- 

 mann ascribes to the organic matter in the soil derived 

 from the sod turned under in 1888. 



(2) Sulphate of potash-magnesia has given rather 

 better results than the muriate with legumes. 



(3) The yield of the unfertilized plat in 1891 showed 

 a noticeable decline as compared with the fertilized 

 plats (one- third less). 



(4) Seeding in drills in all cases gave a larger yield of 

 grain than seeding broadcast. 



(5) Muriate of potash seems to produce larger yield 

 in case of grain crop. 



(6) Soy beans should be planted in drills, otherwise 

 they are interfered with by weeds. 



(7) Vetch and oats yield larger crops earlier in the 

 season than soy beans. They also yield a larger crop 

 of dry fodder for winter use.
