The results show a material gain in the crop from the 

 use of Nitrate of Soda, but the applications on plots 5 and 

 6 are perhaps greater than will prove economical. The 

 quality of the crop was given exhaustive examination, with 

 the results that plots 2, 3, 4 and 7 graded all the same, and 

 the highest. The quality on the other plots was not ma- 

 terially different. As a result of the investigation, Dr. Dyer 

 recommends Nitrate of Soda strongly for hop growing, but 

 suggests early applications. 



Formula for Hops: 



Nitrate of Soda 600 lbs. 



Acid phosphate, 200 lbs., or Thomas slag 300 



Sulphate of potash, 100 lbs., or unleached wood ashes... 400

Corn. 



The crop is especially adapted for making use of rough 

 age of all sorts. It has a long season of growth and 

 makes its heaviest demand for food late in the season 

 when the conditions are such that soil Nitration is 

 at its highest period of development. It is also a 

 deep rooting crop and capable of drawing its food 

 and water from great depths. It needs vast quan- 

 tities of water, and the tillage must be very thorough 

 that an even earth mulch may be practically con- 

 tinuous. In the early spring it frequently starts off 

 slowly, and on this account should have some help 

 in the form of hill applications of highly available 

 plant food. 



Sweet corn is quite a different crop from field 

 corn; it has a much shorter period of growth and 

 should be fertilized much more heavily. The ^^ ^
