32 TOBACCO CULTURE. 



FERTILIZING. 



In taking up this important branch of the subject, it will 

 be well to give a brief review of the object and value of fer- 

 tilizing, together with some of the more important facts 

 which seem to influence the field practice of successful 

 growers. 



Tobacco is a rank, rapid growing, and heavy-feeding 

 plant, and requires liberal supplies of plant-food. The care- 

 ful experiments of Dr. Goessman, of the Massachusetts Ex- 

 periment Station, and of Prof. Stockbridge, of the Florida 

 Experiment Station, furnish information of great practical 

 value to the planter. 



As a result of these investigations, the quantities of 

 Phosphoric Acid, Nitrogen and Potash per acre suggested 

 by these two authorities are as follows: 



Phosphoric Acid Nitrogen Potash. 



Dr. Goesmann 60 Ibs. 100 Ibs. 300 Ibs. 



Prof. Stockbridge 75 Ibs. 180 Ibs. 300 Ibs. 



Average per acre 67 Ibs. 140 Ibs. 300 Ibs. 



The plant food found by chemical analysis in the to- 

 bacco plant furnishes a fair guide in determining the kind 

 and amount of fertilizer to use.. Of course, not only the 

 leaf but the whole plant must be accounted for in figuring 

 out the actual plant food taken up. While the leaf is the 

 object of tobacco growing, the leaf cannot be grown without 

 the stalk, roots, etc. The analyses of the whole plant made 

 t>y Prof. Stockbridge indicate the following plant food re-
