CONSTANTS FOR ALLUVIAL SOIL, THIRD CROP. 



n=110 Ba=1.0075 



A=68.7363 E5=.7125 



3=15.6697 Ec=1.908 

 C=22.79% 



Conclusions. 



From the foregoing it may be seen that the second crop clover has 

 more flowers in the head than the first crop clover, and that black 

 loam underlaid with gravel is the best soil for the production of red 

 clover.
