 half the commercial fertilizer and one-half 

 the seed, except clover seed, which the ten- 

 ant is required to furnish. 



This lease provides for two clover crops 

 out of every five crops raised, thus supply- 

 ing nitrogen abundantly, and the terms of 

 the lease are such that it is necessary for the 

 tenant to keep live stock to consume these 

 clover crops in order to secure the most 

 profitable returns. The feeding of the 

 clover makes it necessary to feed some or all 

 the maize and may lead to buying addi- 

 tional concentrates. 



Stable manure is thereby supplied for the 

 field which is to raise maize, while mineral 

 fertilizers may be applied to the fields 

 sown to wheat. On the limestone soils of 

 the eastern states 50 pounds each of phos- 

 phoric acid and potash per acre applied to 

 the wheat, and 10 loads of stable manure per 

 acre to the maize will probably be found 

 sufficient to maintain the crop producing 

 power of the soil.
