3 TOBACCO CULTURE. 



wilh. stable manure, as the country develops and the lands 

 become impoverished. 



Cigar Tobacco is chiefly produced by the use of com- 

 mercial fertilizers made specially for tobacco, chemical 

 manures or vegetable by-products. Barn-yard manure, 

 strengthened by chemicals is used somewhat in Pennsyl- 

 vania, Ohio and Wisconsin. In the Connecticut Valley, ap- 

 plications of 3000 Ibs. of concentrated chemical fertilizers 

 per acre is the rule rather than an exception. Experience 

 shows that better results follow where the nitrogen is sup- 

 plied in various forms and at several applications; hence it 

 is common to apply nitrate of soda, or dried blood, with cot- 

 ton seed meal, or castor pomace, as a second application for 

 "working in" after the plants are well started. 



The full quantity of phosphoric acid and potash should 

 be applied at one time, and "broadcasted" before planting. 

 The use of high grade fertilizers made expressly to meet the 

 requirements of cigar-leaf is extremely common, and these 

 are generally based on the actual needs of the crop as shown 

 by chemical analysis. 



The formulas of fertilizers and applications used are 

 numerous. The general aim and practice is, to provide the 

 three essentials in the proportions of about 60 Ibs of Phos- 

 phoric Acid, 75 Ibs. Nitrogen, and 120 Ibs. of Potash per 

 acre. This would correspond to an application of 1500 Ibs. 

 per acre of a fertilizer containing 4 per cent available phos- 

 phoric acid, 5 per cent nitrogen, and 8 per cent actual pot- 

 ash. If doubled, this would make about the maximum ap-
