 INVESTIGATIONS.

Prof. J. F. Duggar, Director, 



Alabama Agricultural Experiment Station. 

 Auburn, Alabama. 

 Sir: 



The following condensed statement of the work of this de- 

 partment for the year 1910, is respectfully submitted: 



1. Adams Project: Soil Requirements by Plant Analysis. 

 Hitherto the work on this project has been limited to Potash 

 in the Cotton Plant. As this narrowed down, the analytical 

 work has been completed, and the manuscri])t will soon be 

 ready for the printer. 



It was decided to extend the scope of the work so as to 

 include both phosphoric acid and potash and use the turnip 

 as the plant for investigation. Three different types of soil 

 Avere selected for the study, and inbedded cylinders were used 

 as containers. The same system of fertilization was used as 

 with the cotton plant, using the three fertilizer constituents 

 alone and in their several combinations. 



2. Adams Project : Arsenate of Lead as an Insecticide. This 

 work was done in co-operation with the Department of En- 

 tomology, only the chemical analysis being done by this de- 

 partment. 



3. Miscellaneous. Under this head is included all the 

 chemical work for the other departments of the Station, as well 

 as for individual citizens of the State, and embraces the chemi- 

 cal I'.nalysis of corn, hays and other crops used in experimen- 

 latifHi, soils, etc. 



Respectfully submitted, 



JAMES T. ANDERSON, 

 Chemist, Soils and Crops Investigations.
