ROTATION OF CROPS. 



it requires twice as much manure and commercial fertilizer to 

 maintain fertility as when used in a rotation of crops. 



In the plats where corn is raised continuously without ma- 

 nure or fertilizer the corn crop has become comparatively worth- 

 less. 



Where there has been rotation with out fertilizers or manure 

 there is still a very good production.

NOTE No fertilizers are to be used in this plat work as the aim is 

 to demonstrate the effects of rotation only. The plats should be a frac 

 tional part of an acre, say, one-tenth, one-twentieth, or one-fortieth of 

 an acre.
