342 Fertilizers 



acre may be regarded as a minimum for soils of medium 

 quality. On lighter soils heavier applications should 

 be made, and on soils previously well enriched with the 

 fertilizer constituents, the dressing may be somewhat 

 less. It must be remembered, however, that it is not 

 economical, from the standpoint of either yield or qual- 

 ity, to be too sparing in the application of fertilizers, 

 because the plant requires large amounts of both nitro- 

 gen and potash, and because it is essential that the plant 

 should have a reasonable excess of these at its command, 

 in order to overcome as far as possible any unfavorable 

 seasonal conditions that may occur. 



In the Connecticut experiments already referred to, 

 amounts greatly in excess of those suggested have been 

 used with advantage, and the following formulas are cited 

 as fair examples of what would be good fertilizers for an 

 acre: 



Cotton-seed meal 2000 Ib. 



Sulfate of potash 300 Ib. 



Precipitated or dissolved bone . . . 200 Ib. 



Lime 300 Ib. 



Total . . 2800 Ib. 

 or 



Cotton-seed meal 1500 Ib. 



Fish 500 Ib. 



Double sulfate of potash 500 Ib. 



Acid phosphate 400 Ib. 



Lome 300 Ib. 



Total . . 3200 Ib. 



In Kentucky and Virginia, on soils naturally richer, 

 smaller amounts have given quite as good results. It is 

 likely, however, that upon the very light soils of certain 

 of the states in which tobacco of high quality is grown, 

 notably Florida, considerably increased amounts may be 

 used with profit.
