Food for jt is difficult to secure a thoroughly matured leaf unless 



the supply of digestible Nitrogen is more or less under 



82 control, a condition not practicable with ordinary fer- 

 tilizers. Should the crop at any time before mid- 

 August take on a sickly, yellow color, Nitrate of Soda 

 should be broadcasted at once, along the rows, and at 

 the rate of 200 pounds per acre. If this broadcasting 

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

 more promptly. 



Tobacco growing is special farming, and should 

 be carefully studied before starting in as a 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 maintained — that is, the surface 

 soil to that depth kept thoroughly pulverized. 



At the Kentucky Experiment Station, experiments 

 were made with fertilizers on Burley Tobacco. The 



land was "deficient in natural drain- 

 age," so that the fertilizers could 

 hardly be expected to have their full effect. Yet, as 

 will be seen by the following table, the profits from 

 the use of the fertilizers were enormous:

The tobacco was assorted by an expert and the 

 prices given as follows: Bright and red, fifteen cents 

 per pound ; lugs, six cents per pound ; tips, eight cents 

 per pound; trash, two cents per pound. 



One hundred and sixty pounds Nitrate of Soda, 

 costing about $3.75, increased the value of the crop 

 $71.20 per acre!
