formulated in Europe with beets dependent on rainfall, to 
our Colorado conditions, where the beets are grown with 
irrigation. This opens up a wide field for experiment and 
research. No one station in any one season can hope to 
compass the problem. The following soil analyses made by 
Mr.Chas. Ryan are presented as a contribution to the subject. 
They should be studied in connection with the analyses of 
the beets grown in the several sections. 
Much more of this work will need to be done before any 
generalizations can be drawn.
