In all cases, if practicahle to do so, we recommend the use of at least 

 one ton of calcium carhonate hroadcast to the acre before using these 

 mixed fertilizers in the drill. The acre apjilications of these mixtures 

 will depend on the varying fertility of the soils, but from GOO to 1,000 

 ]K)unds to the acre will likely be about an average application in most 

 parts of Xorth Carolina. 



Ground limestone can at this time (1916) be laid down at Raleigh in 

 bulk at $2.60 a ton. The normal ]»rice for 16 per cent acid phosphate 

 is not over $15 a ton. The average i)rice of cotton-seed meal is not over 

 $.'50, and nitrate of soda does not generally sell for more than $60 a ton. 

 Basing our calculations on these prices, the cost per ton of the different 

 formulas given below has l>een worked out and attached. Of course, the 

 whole of this discussion presupposes home mixing of the fertilizer ingre- 

 dients. 



A New Fertilizer Formula for Small Grain 



1,200 pounds of ground limestone or marl, 

 600 pounds of 16 per cent acid phosphate, and 

 200 jjounds of cotton-seed meal or fish scrap. 

 Cost, aWit $0.06 a ton. 



Jfew Ferfilizor Formula for ("otton and Corn 



1,000 pounds of ground limestone or marl, 

 600 i)ounds of 16 per cent acid j)h()sphate, and 

 400 pounds of cotton-seed meal or some other ammoniated 

 goods carrying an equal amount of nitrogen. 

 Cost, about $11.80 a ton. 



>ew Fertilizer Formulu for Tobacco 



1,200 pounds of ground limestone or marl, 

 400 pounds of 16 per cent acid phosphate, 

 .'l')!) j)ounds of cotton-seed meal, and 

 oO pounds of nitrate of soda. 



Any other material carrying an e<|nal amount of niti-ogen may Ix^ 

 substituted for the cotton-seed meal, such as dried blood, fish scrap, and 

 so on. Cost, about $9.21 a ton. 



>ew Fertilizer Formula for retiniits 



1,200 pounds of ground limestone or marl, 

 GoO i)ounds of 16 j)er cent acid idiosphate, 

 100 pounds of cotton-seed meal, and 

 50 pounds of nitrate of soda. 



The cotton-seed meal may be replaced by any other material carrying 

 an equal amount of available nitrogen. Cost, about $0.4.'^ a ton.
