230 EXPERIMENT STATION RECORD. [Vol.40 



Applications of different quantities of phosphates and potash salts gave 

 varying results, determined mainly by the quality of the peat soil and the pre- 

 ceding fertilizer treatment. Thomas slag used on grass was followed by a 

 higher yield than was secured from the corresponding quantity of phosphoric 

 add as superphosphate applied with 37 per cent potash salt. When used with 

 kainit, Thomas slag and superphosphate were apparently of equal value. The 

 37 per cent potash salt showed somewhat better results than those obtained 

 from kainit when both were applied with superphosphate Nitrate of Boda as 

 a top-dressing on peaty soils of a high nitrogen content was not profitable as 

 a rule, but in Norbotteil on a Bedge bog soil, not yri perfectly reduced, its use 

 gave a good increase in yield, although the total nitrogen content of the soil 

 was high. 



Barnyard manure on this type of soil proved quite effective the second year 

 after application. In one experiment the residual effect of the manure the 

 fourth year after application proved unimportant The total profit derived 

 during a live-year period from loo kg, (220 lbs) of barnyard manure, the price 

 of hay being 5 8re per kilogram, was 96 5re (24 cts. i. For good yields of dif- 

 ferent crops in rotation mi these peaty soils fertilised treatment was required 



each year. The addition of commercial fertilizers to barnyard manure in 

 growing root crops proved generally (piite profitable. 



OatS <>n moss soils gave an average yield, and of the three varieties grown 

 Guldregn was the most productive. Mixed crops. Including legumes, produced 

 good yields of green forage in these tests. On all of the better soils average 

 yields of root crops were Becured, and in two of the localities where this work 

 was in progress the common flal turnip proved more productive than either 

 tin- Ostersundom or the Bortfeld turnip.

Pumpkins and corn grown together resulted in yields of 666 and 1.S40 lbs. 

 per acre, respectively, as compared with yields of 6,400 n>s. of pumpkins ami 

 1,800 lbs. of corn when grown alone.
