tilize the tomato with some fprm of phosphorus. The usual 

 practice is to employ the treated phosphatic rock, acid phosphate, 

 containing about 16% of available phosphoric acid. An applica- 

 tion of 500 to 700 pounds to the acre is probably as much as can 

 be used to advantage on any soil. If potash is available at reason- 

 able prices, it might also be used at the rate of about 100 pounds 

 to the acre. Nitrogen may also be needed, and, if so, nitrate of 

 soda, 50 to 100 pounds to the acre, may be the cheapest source. 

 Heavier applications of fertilizer are required with close setting 

 and staking. 



All fertilizers should be applied after the ground is plowed, and 

 mixed with the soil by thorough harrowing. Small amounts of 

 nitrate of soda are sometimes used as a top dressing around the 

 plants, but thoroughly mixed with the soil with a hoe or cultivator. 

 A teaspoonful to each plant will be ample in quantity. The best 

 method, however, is to apply all of the fertilizers before the plants 

 are set in the field.
