having been used by some of the best growers — with 5 cords of manure 

 every other year. In recommending a fertiUzer formula for any crop it 

 is realized that it is impossible to compound one that will answer equally 

 well for all conditions, as each farm and sometimes each field is an in- 

 dividual problem. It is felt, however, that a formula may be recom- 

 mended that will answer in many cases, changes and substitutions to be 

 made to fit individual conditions. 



The following recommendations are made with the understanding that 

 the tobacco stalks from healthy tobacco (plants suffering from calico and 

 other diseases being rejected) be cut into short lengths, returned to 

 the land acre for acre and thoroughly disked in previous to plowing. 



Formula No. i. 



To be used with lo tons of manure per acre. 

 200 pounds ammonium sulfate, or a like amount of calcium cyanamid, 

 1700 " cottonseed meal ( 6.50 per cent nitrogen), 



500 " acid phosphate ( 16 per cent grade). 

 This formula will test about 6.6 per cent nitrogen, 5 per cent avail- 

 able phosphoric acid and i per cent potash. 



Formula No. 2. 



To be used per acre without manure. 

 200 pounds ammonium sulfate, or a like amount of calcium cyanamid, 

 2000 '• cottonseed meal ( 6.50 per cent nitrogen), 

 300 " fish or concentrated tankage, 

 600 " acid phosphate ( 16 per cent grade). 

 This formula will test about 6.9 per cent nitrogen, 6 per cent avail- 

 able phosphoric acid and i per cent potash. 



In the above formulas 300 to 400 pounds of castor pomace may be 

 substituted for a like amount of cottonseed meal if desired. Precipitated 

 bone may be used in place of acid phosphate in amounts to furnish 

 about the same phosphoric acid. Either of the two formulas are recom- 

 mended for old tobacco land. On new land formula No. 2 may be used 

 with a medium application (8 to 10 tons) of manure per acre. 



Llme for Tobacco. 



The results of many chemical tests on tobacco soils during the past 

 year, taken according to directions from this laboratory, have indicated
