These results show in a general way that the NO3 lowers

 and June, however, show an increase, uxthough there is

 was considerable reduction of NO3, in May, and a alight 

 reduction in moisture. After this period the amount of 

 NO^ was fairly constant with a slight decrease in moisture 

 content. It is hardly probable that this was beneath the

 In the surface. The roots of the cotton plant doubtless 

 penetrated somewhat into the third foot of soil, but did 

 not reach the fourth foot. The data shows a valuable 

 reserve in this soil beneath three feet, accumulated by 

 leaching from the surface which under the proper condition* 

 of capillarity would be of material advantage to the plant,
