SOILS 



The table following shows the composition of average 

 farm manures : 



Solid and liquid manure. In the liquid portions of the 

 manure the digested nitrogen is found, as is also the 

 larger part of the potassium. This explains why the loss 

 is so great, from a money standpoint, when liquid manure 

 is not preserved properly by absorbents, or otherwise held 

 so as to prevent its loss from being washed away. Yet 

 in just this way the greater value of stable manure is 

 never secured to the farm. On the average farm little 

 consideration is given this liquid portion. And then to 

 think : it is the most valuable product made on the farm. 

 And you let it get away ! 



In the undigested portions of manure some nitrogen is 

 present also. A large part of the phosphorus is contained 

 in the solid parts. Since nitrogen and potassium are con- 

 tained in liquid manures, and, at the same lime, are very 

 soluble in water, the active influence of this sort of 

 manure in forcing vegetation is recognized at once. You 

 can do no wiser thing than to begin at once in the saving 

 of all liquid manures clearly the most valuable home- 

 produced manure.
