The Composition and Use of Fertilizers.

will often he found most advantageous to apply a top dressing of 

 100 pounds of nitrate of soda and 200 pounds dissolved rock per 

 acre after the plants have been transplanted and well started in 

 growth. Later, when the heads begin to form, another 100 pounds 

 or more of nitrate of soda per acre may be applied as a top 

 dressing.

Same as for beets grown for fodder purposes. 



Same as for cabbage.

125 to 250 pounds nitrate of 

 soda; 100 to 200 pounds dried 

 blood; 150 to 300 pounds cot- 

 ton seed meal or ground fish. 



500 to 1,000 pounds dissolved 

 rock. 



200 to 400 pounds muriate of 

 potash. 



Suggestions. — The above mixture should be used when the plants 

 are set. This may be followed at intervals with a top dressing of 

 100 pounds of nitrate of soda per acre. On muck soils rich in 

 available nitrogen, special feeding of nitrogen is not equally im- 

 portant. Abundance of water is a great essential for celery in 

 addition to other forms of plant food. Abundance of soluble 

 nitrogen, other conditions being favorable, promotes rapidity of 

 growth, which is attended by the high market qualities of crisp- 

 ness and sweetness.

 ash. 



Suggestions.- — ■ It is desirable that in addition to the amounts of 

 plant food given, an abundance of lime shall be kept in soil where 

 cherries are grown.
