carefully preserved manure will be higher in available plant 

 constituents than one not so handled. Moreover, the agricul- 

 tural value of such manure will be higher. This is shown 

 by actual tests from Ohio. 1 Over a period of fourteen years, 

 in a three-years' rotation of maize, wheat, and hay, a stall 

 manure gave a yield 38 per cent, higher than that with a yard 

 manure.

INCREASE YIELDS FROM YARD AND STALL MANURE. 



In New Jersey, fresh manure showed a gain in crop yield 

 53 per cent, higher than leached manure over the three years 

 immediately following the application. Such figures are 

 worthy of careful consideration. 



302. Application of manure. — In the application of ma- 

 nure to the land, the same general principles observed in the 

 use of any fertilizer should be kept in mind. Of these, fine- 

 ness of division and evenness of distribution are of prime im- 

 portance. The efficiency of the manure may be raised con- 

 siderably thereby. Moreover, it is generally better, since the
