 216 to ammonia, 5 per cent.).

Nitrate of soda 100 lbs.

This mixture will contain: available phosphoric acid, 7.2 

 per cent.; potash, 7.7 per cent.; nitrogen, 3.1 per cent, (equal 

 to ammonia, 3.8 per cent.). 



Four hundred to one thousand pounds of these mixtures 

 should be used to the acre. 



The mixtures made from formulas Nos. 2 and 3 are some- 

 what more concentrated than that from No. i, on account 

 of cotton-seed meal containing less ammonia than fish scrap 

 and dried blood. The three formulas are given to enable the 

 use of any one of the three main organic, nitrogenous mate- 

 rials — dried blood, fish scrap and cotton-seed meal. In the 

 coast sections, fish scrap and meal are both easily obtained; 

 some distance inland meal is more accessible, while in the 

 more western end of the tobacco belt it will be found con- 

 venient to use dried blood. All three are good sources of 

 ammonia for tobacco. The other materials — nitrate of 

 soda, sulphate of potash and acid phosphate — are the same 

 for all mixtures. 



Occasional requests are made for formulas furnishing 

 as much as 10 per cent, of potash, and No. 4 has been 

 arranged to meet needs of this nature. It is known that 

 excellent tobacco, in quality and quantity is grown by the use 

 of fertilizers of this class, and some of our farmers greatly 

 prefer them to others containing less potash. It takes con- 

 siderable observation and experimentation to determine the 

 best practice in matters of this kind. 



A limited quantity of stable manure is very beneficial to 

 tobacco and it succeeds well after peanuts. These materials 

 add ammonia to the soil, and where heavy applications of 

 fertilizers are to be made in connection with manure, and on 

 peanut land, it would be well not to have so much ammonia 

 in the fertilizers as is used in the ones employed on land not 

 having other ammonia materials put on them. Formula
