Rotations, Manuring and Fertilizing 61 



CURRENT FERTILIZER PRACTICE 



Fertilizer practice for strawberries, as for other crops, 

 depends greatly on the soil and other factors ; but the 

 plant, being shallow-rooted, responds readily to fertilizers 

 as a rule, if the land is in need. Various geographical 

 practices or tests are here recorded. 



Canada and northern United States, 



In this region the main dependence is farm manures. 

 H. F. Hall of New Hampshire recommends a choice of 

 one of these three treatments : ^ 



" 1. Fifteen to eighteen cords of stable manure per acre. 



" 2. When manure is scarce, eight to ten loads of manure 

 supplemented with seventy-five bushels of unleached hard 

 wood ashes and 600 pounds of fine ground bone, har- 

 rowed in before the plants are set. 



"3. When no manure can be obtained, use 1500 to 

 2000 pounds per acre of the following fertilizer; broad- 

 cast all of it and harrow it in before setting the plants : 

 100 pounds nitrate of soda; 500 pounds tankage; 1000 

 pounds acid phosphate; 400 pounds muriate of potash. 

 This fertilizer analyzes 2.5 per cent nitrogen, 10 per cent 

 phosphoric acid, and 10 per cent potash. In addition to 

 the above treatment, top-dress with 100 to 200 pounds of 

 nitrate of soda when the plants are in bloom, to increase 

 the size of the fruit." 



L. H. Bailey reported on a three-years test of fertilizers 

 in Oswego County, New York, as follows : ^ " These ex- 

 periments show the superiority of potassic and phosphatic 

 fertilizers as compared with the nitrogenous. The nitro-
