in the fertilizers used and were I to buy a prepared fertilizer to- 

 day for our general crops I would get some one of the so called 

 "special potato fertilizers," since they have more potash than 

 any others on the market. 



My advice to farmers is to buy dissolved bone-black, con- 

 taining sixteen per cent of soluble phosphoric acid. Muriate 

 of potash containing fifty per cent of actual potash and sulphate 

 of ammonia containing twenty per cent, of nitrogen and from 

 these crude materials mix such combinations as are best suited 

 to the soil and crops under cultivation, these materials may be 

 obtained from any fertilizer manufacturer, they are in forms that 

 are ready for use, there is nothing to do but to mix the required 

 amounts exactly as one would mix corn meal, shorts, and cot- 



IT' 



tonseed together for feedi ig. It is no more labor nor is there any 

 danger. Every farmer can experiment for himself if he buys 

 his deficient plant iooA in these separate substances, for he is at 

 liberty to mix them in any proportion that he pleases, and in time 

 it would be possible for each to supply those elements which the 

 soil most needed, and to withhold those not specially required. 

 There certainly can be no loss, for in any event the crude chem- 

 icals will be as cheap as the manufactured goods. 



The following combinations can be used to good advantage 

 and have all been tested and found well adapted to our condit- 

 ions in New Hampshire. Each combination is for one acre and 

 in no case should more than 150 pounds be put in the hill, the 

 remainder being sown broadcast.
