Cranberries grow best on low swamps, or bog-lands rich in decaying organic 

 matter. These lands usually are excessively rich in nitrogen, but poorer in 

 phosphoric acid and potash so that fertilizers should be applied accordingly. 

 Many times, applications of nitrogenous materials are entirely unnecessary.

 150 to 300 sulphate of ammonia; or 

 450 to 900 fish guano ; or 



6,000 to 12,000 stable manure. 

 360 to 720 acid phosphate ; or 

 110 to 220 double superphosphate ; or 

 450 to 900 ground bone. 

 130 to 260 muriate of potash ; or 

 130 to 260 sulphate of potash ; or 

 520 to 1,040 kainite ; or 



1,300 to 2.600 wood ashes. 



Well decomposed stable manure is especially beneficial, also nitrogen in 

 form of fish guano. If cucumbers are grown for pickling purposes and if a 

 quick growth is desired, then apply most of the nitrogen in form of nitrate of 

 soda, in several partial applications.

Too much nitrogen produces rapid growth of foliage and the plants be- 

 come more easily susceptible to disease and mildew. Nitrogen applied in some 

 slow-acting form is usually best.
