Fig. 7.—Diagram showing the distribution of nitrates in plot G before and after irrigations. Season of 1916. 
The data presented in figure 9 show a strong and rather consistent 
lateral movement of nitric nitrogen in soil L. In the upper 6 inches the 
variation during the season was from 0.69 to 37.28 mgm. From 6 to 18
