REPORTS OF PROJECT LEADERS ON RESEARCH WORK 



FOR THE YEAR 1940 



AGRICULTURAL CHEMISTRY 



The agricultural chemistry department for several years has 

 cooperated extensively with other departments which have needed 

 assistance in chemical analysis. This has permitted a fuller utiliza- 

 tion of both personnel and equipment in the chemistry department 

 and has made it unnecessary to duplicate either in carrying on var- 

 ious projects in other departments. 



During 1940, the agricultural chemistry department has assisted 

 the agronomy department with 5 projects ; the horticulture depart- 

 ment with three projects; the dairy husbandry department with one 

 project ; the entomology department with one project ; and the poul- 

 try husbandry department with one project. Abstracts of these proj- 

 ects are included with the reports of the cooperating departments. 

 The Chemical Composition of Timothy (T. G. Phillips and T. O. 

 Smith) 



A series of samples, simulating grazing, was taken in 1939, and 

 determination of the soluble carbohydrates is nearly completed. The 

 difficult analytical problems involved in the determination uf the 

 solube carbohydrates are being studied. Dr. Kazimierz Strzemienski, 

 employed in August to assist with this work, is making valuable con- 

 tributions to this phase of the study. 



A brief paper is being printed describing the method developed 

 under this project for the determination of small amounts of reducing 

 sugars. It will appear in the Journal of the Association of Official 

 Agricultural Chemists.

Inspection of Feeding Stuffs and Fertilizers (T. O. Smith and H. A. 

 Davis) 



In the enforcement of the law regulating the sale of concentrated 

 commercial feeding stuffs, 485 brands of these products were analyzed 

 for the state Department of Agriculture, the analyses requiring ap- 

 proximately 3760 individual determinations. 



One hundred nine brands of commercial fertilizers were also
