It will be seen that 2,000 pounds of each must contain as 
follows:

8 | Average of 8 tobacco fertilizers ...| 57.8 | 165.0 92.8 
4 | Average of 12 cabbage fertilizers..| 92.2 | 1383.8 140.6 

In order that the nitrogen may not be wholly as nitrate and 
in danger of being in part lost before it is demanded by the 
growing crop, we will supply half in the form of nitrate of soda 
and half as ammonia sulphate. 
In the tobacco manure we will supply the potash in the form 
of sulphate. | 
In order to supply the necessary amounts of the fertilizing 
constituents given in the above table it will be necessary to take 
as follows:

Should one prefer using potash in the form of sulphate in the 
potato manure, the required 129 pounds would be furnished by 
958 pounds of the sulphate in place of the 251 pounds of 
muriate.
