382. Influence of Fertilizers upon Composition of 

 Wheat. Experiments by Lawes and Gilbert (Rotham- 

 sted Memoirs, Vol. Ill) show that the different kinds of 

 manure, as nitrogenous, mixed and mineral, influence 

 the yield but not materially the composition of the grain. 

 During the time of the experiment, covering a period of 

 twenty years, the nitrogen, phosphoric acid, and potash 

 in the dry matter of the grain were fairly constant, and 

 when different manures were used, there were no greater 

 variations in the composition of the grain than were 

 observed between crops upon the same plots similarly 

 manured during different seasons. Climatic conditions 

 influenced the composition of the kernel to a greater 

 extent than did fertilizers.

 kins' and Winton's "Average Composition of American 

 Feeding Stuffs," spring wheat is given as containing 12.5
