This is an important fact for it is well known that clover 

 stores up nitrogen in the surface soil, its long deep roots gather- 

 ing the costly element from the sub-soil and bringing it up with- 

 in the reach of the cereals, or other crops, thus by the use of 

 comijinations containing a large per cent, of potash, we are able 

 indirectly, through the growth of clover to increase the available 

 nitrogen in our surface soils. 



So far as results have been obtained we are justified in saying 

 that chemicals rightly proportioned can be used as a complete 

 substitute for farm yard manure, that they will produce as great 

 a value of crop, dollar for dollar as manure ; and that they improve 

 the quality of the hay by increasing the clover and, indirectly, the 

 supply of available nitrogen is increased. 



In conclusion I wish to say that I am thoroughly convinced 

 that our fertilizer manufacturers must give us in New Hampshire 

 more than four per cent, of potash and from other New England 

 States, I am receiving letters which convince me that New En- 

 gland as a whole would be benefited by ten per cent, of potash
