will supply the needs of the crop with a fair degree of uni- 

 formity for the three seasons it would normally be expected 

 to occupy the land. 



FERTILIZATION OF STRAWBERRIES 



While the use of manures and green crops is highly to 

 be commended, one should not forget that the strawberry, 

 like all other fruit crops, draws freely on the potash and 

 phosphoric acid supply of the soil; nor should one overlook 

 the fact that yard manure is not a well-balanced plant food, 

 being deficient so far as the strawberry is concerned, in 

 available supplies of both potash and phosphoric acid. 

 Growers who resort to the use of green crops should bear in 

 mind that, in a sense, they only turn over the mineral plant 

 food supply of the soil, but do not add anything to the store 

 of the mineral elements potash and phosphoric acid. 



STRAWBERRIES USE LARGE AMOUNTS OF 

 PLANT FOOD 



Conservative estimates indicate that two good crops of 

 strawberries, including the production of the vine and the 

 fruit, will remove, during the three years of growth of the 

 crop, at least 223 pounds of nitrogen, 375 pounds of potash 

 and 83 pounds of phosphoric acid per acre. Since the crop 

 is generally planted on soils of a rather light character, they 

 will, in most instances, not be naturally as well supplied with 

 potash and phosphoric acid as soils of a heavier type and
