Society and the other, a series of six samples, by the Association of Feed 

 Control Officials. More than 100 laboratories analyze these samples and 

 our laboratory stands very well in relation to others reporting on this work. 



We have continued collaborative work with the Association of Official 

 Agricultural Chemists in the development and improvement of analytical 

 methods. This laboratory is especially concerned with the development of 

 methods for determining nitrogen in fertilizers. 



Numerous inquiries by residents of the State have been made, and 

 answers supplied concerning feed and fertilizers. Many of these inquiries 

 can be answered without analytical work. However, a limited number of 

 such analyses are made each year in specialized cases.
