and six to eight per cent, potash, the latter always in the ^°°^ *°^ 



form of sulphate. This fertilizer is used in quantities per ^" ^ 



acre as low as 400 pounds, and as high as 3,000 pounds. ^^ 

 It should always be supplemented by a top-dressing of 

 Nitrate of Soda, along the rows of young plants, ranging 

 from 200 to 600 pounds per acre. Manufacturing tobaccos 

 are particularly benefited by the application of Nitrated 

 ammoniates, of which class of fertilizer chemicals Nitrate of 

 Soda alone is cheap enough for use as plant food. While 

 the production of leaf may be enormously increased by 

 abundant use of this Nitrated ammonia, the other plant 

 food elements should also be used to secure a well matured 

 crop. In the case of cigar tobaccos, Nitrated ammoniates 

 should be used exclusively, as it is difficult to secure a 

 thoroughly matured leaf unless the supply of digestible 

 ammoniate is more or less under control, a condition not 

 practicable with ordinary ammoniates. Should the crop at 

 any time before mid-August take on a yellow, sickly color. 

 Nitrate of Soda should be broadcasted at once, along the 

 rows, and at the rate of 200 pounds per acre. If this broad- 

 casting can be done just before a rain, the results will appear 

 promptly. 



Tobacco growing is special farming, and should be 

 carefully studied before starting in as a tobacco planter. 

 For small plantations, the plants are best bought of a regular 

 seedsman. The cultivation is always clean, and an earth 

 mulch from two to three inches in depth should be main- 

 tained — that is, the surface soil to that depth kept thor- 

 oughly pulverized.

This crop prefers a soil lighter than Irish potatoes, 

 but the preparation of the soil is much the same. It is an 

 underground crop, and must not have to mine room for its 

 roots. It should follow a clean cultivation crop, and be 

 kept very clean itself. Too much ammoniate fertilizer
