soils, the omission of lime at the proper time will neces- 

 sitate re-seeding to secure a good stand of grass. 



All the elements of fertility are 91 



essential so that ordinarily complete f er- 

 tilizers may be used, Nitrate being used 

 as a top dresser, though on some soils 

 rich in phosphoric acid or potash, one or both of these 

 ingredients may be used in small quantity. This is 

 particularly true of phosphates after lime has been ap- 

 plied to the soil, since lime aids to set the phosphoric 

 acid free from its natural insoluble combinations. 



Grass seems to demand less phosphoric acid than 

 was applied in the test; but it responds with increasing 

 profit to applications of Nitrate of Soda up to 250 

 pounds to the acre when ample supplies of potash and 

 phosphates are present. 



No stable manure has been used upon the field 

 under experiment for over twenty years. 



The Bulletins of the Rhode Island Agricultural 

 Experiment Station, or Farmers' Bulletin No. 77, pub- 

 lished by the United States Department of Agriculture, 

 tells how and when to use lime. Details of excellent 

 grass experiments, to be found in recent Bulletins 

 issued by the Rhode Island Agricultural Experiment 

 Station, Kingston, Rhode Island, tell about Nitrate of 

 Soda. 



It may not be out of place here to 



mention the fact that Mr. Clark's f'^A

 average of 9 tons of cured hay per 

 acre for 11 years in succession, has been heralded 

 throughout the United States. He attributes his suc- 

 cess largely to the liberal dressings of Nitrate of Soda 

 which he invariably applies to his fields early in the 

 spring, and which start the grass off with such a vigor- 

 ous growth as to shade and crowd out all noxious 

 weeds before they get fairly started and which result 

 in a large crop of clean and high priced hay. 



It is also known that many who have tested his 

 methods have met with failure chiefly because they 

 neglected to supply the young grass plants with a
