<rf actual potash and sulphate of ammonia, containing twenty 

 per cent of nitrogen, are all of the substances required for pre- 

 paring such fertilizers as will give the best results. These can 

 be bought of any wholesale dealer in, or manufacturer of fertili- 

 zers. They are perfectly harmless substances, as easily and 

 safely mixed as corn meal, shorts and middlings. 



The quantities required per acre will, of course, vary, but 

 from Table I, we may easily get the amount that was actually 

 used per acre, on any given plot, by multiplying the quantities 

 given in the table by twenty, for example : 



Plot 10 gave best yield; there was used on this at the fol- 

 lowing rate per acre : 



Dissolved bone-black, 330 lbs. 



Muriate of potash, 100 lbs. 



Sulphate of ammonia, 70 lbs. 



500 lbs. 



For the third time I will reprint the combinations which 

 have now been tested for the past five years : 



CORN. 



(Also for potatoes on land where no manure has been used for 



many years.) 



Dissolved bone-black, 325 lbs. 



Muriate of potash, 100 lbs. 



Sulphate of ammonia, 75 lbs. 



500 lbs. 



POTATOES. 



(Following a manured crop.) 

 Dissolved bone-black, 340 lbs. 



Muriate of potash, 160 lbs. 



500 lbs. 



I would only ask the farmers of New Hampshire to try these 

 combinations, even if at some trouble and extra expense, for I 

 am certain that on by far the greater part of our soils, such 

 Mixtures will prove superior to the prepared goods as now com- 

 pounded.
