There is shown a speedy reduction of nitrogen 

 both on the ends and in the corn to a point which would 

 seeir to seriously limit if not prohibit plant growth.

The suimnarized comparison shows a much more spee4- 

 y dim.inuition of the nitrogen than of the moisture. The 

 nitrogen contents lowers with the moidture not only in 

 this plat, but holds true on the part of all plats where 

 crops were grown. (See Table "A" Appendix) But the ni- 

 trogen lowers relatively much more rapidly when a large 

 crop pf "weeds" were grown. It is interesting to note that 

 the nitrogen content of the corn grown mn this plat was only
