On strong soils such as that of these plots, the best Food for 

 fertilizer combination for annual application appears to be : 



400 pounds phosphate. 8 s 



200 pounds muriate of potash. 

 250 pounds Nitrate of Soda. 



No stable manure has been used upon the field under 

 experiment for over twenty years. 



Whole Field, except Center, Fertilized with Fourteen Per Cent. Acid Phosphate, 

 Six Hundred Pounds; Sulphate of Potash, Two Hundred Pounds; 



Nitrate of Soda, Two Hundred Pounds. 



Square in Center of Field had Six Hundred Pounds Acid Phosphate, 



and Two Hundred Pounds Sulphate of Potash, but no 



Nitrate of Soda. 



The Bulletins of the Rhode Island Agricultural Experi- 

 ment Station, or Farmers' Bulletin No. 77, published 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.
