THE ROTATION OF CROPS 



when the owner operates the farm may 

 not be desirable when the farmer is a 

 tenant. When a farm is rented, the 

 lease should provide that clover or other 

 legumes occur with sufficient frequency to 

 keep up the supply of nitrogen without the 

 purchase of a considerable quantity in chem- 

 ical fertilizers. The lease should be so 

 drawn as to make it necessary for the tenant 

 to keep live stock in order to realize the 

 largest profit. The landlord should pro- 

 vide an equitable proportion of the mineral 

 fertilizers when such are required. 



The provisions of the lease and the char- 

 acter of the rotation will necessarily vary 

 with circumstances, but the following sys- 

 tem of tenant farming which has been em- 

 ployed for many years in Maryland will 

 illustrate the principles just stated: 



The lease provides for a five-course rota- 

 tion consisting of maize, wheat, clover, 

 wheat, clover. The landlord and the ten- 

 ant share the maize and wheat equally, but 

 the clover for hay or pasture goes entirely 

 to the tenant, unless hay is sold, when it is
