(c) Other Activities of the Fertilizer Section. 

 After the completion of the fertilizer inspection work an op- 

 portunity was found for the analysis of a great variety of ferti- 

 lizing by-products which had been sent to the laboratory by 

 farmers and farmers' organizations; also, during November, 

 December, January, February and March, much co-operative 

 analytical work was done on some of the problems of the Agri- 

 cultural Department, particularly with reference to the analy- 

 sis of crops grown in certain experiments both in the field and 

 with pots. They may be briefly summarized as follows: — 



Weights, dry matter and duplicate phosphoric acid determinations on 



157 samples of rape. 

 Weights, dry matter and duplicate phosphoric acid determinations on 54 



samples of millet seed and straw. 

 Weights and dry matter determinations on 392 samples of millet seed 

 and 392 samples of millet straw; also 140 potash, 128 nitrogen and 

 22 phosphoric acid determinations were made on this series. 

 Thirty samples of soil and subsoil collected in various sections of the 

 State have been analyzed for their content of acid soluble potash as 

 well as for their mechanical analyses. 

 Five hundred and sixteen different substances have been received and 

 analyzed for farmers and the various departments of the experiment 

 station, and may be grouped as follows : — 



Fertilizers and fertilizer by-products, 198 



Lime products, 22 



Soils for lime requirements and organic matter tests, . . . 289 

 Soils for partial analysis, water soluble constituents, ... 5
