Early rain killed many of tlit.' beets in tlii.s Held and as a result they stood very tliin 

 on the <,M(tnnd. The relatively high yield on plot 1 indieates the presence of some 

 nniial\iral eondition. A study of the yields of jjlots 1 to S indieate that nitrof^'en 

 and jjotash are more needed on tliis soil than jdiosphoric aeid. This eonelusion is 

 further verified by the fact that the addition of phosphoric acid in plot !) seems to but 

 slightly increase tlu; yield over that of plot 7 without the phosphoric acid. Further- 

 more, as single elements, nitrogen and potash gave higher yields tlian phosphoric acid 

 in every case except the potato plots.

Beets were sown on this experiment, but the severe rains destroyed them. Plot 5 

 was in a sag where the wash from otlier plots materially benefited the crops. Leav- 

 ing out this plot, there appears a need of complete fertilizers to improve this soil. 

 Further experimenting will be necessary to determine the particular elements most 

 beneficial. Unfortunately, Mr. Thompson will be unable to continue the experiment 

 another year.
