SOUTHERN FIELD CHOPS 



99. Corn products. — From the corn plant are made 

 great numbers of products. Among those made from the 

 grain are corn meal, grits, hominy, and corn flakes, — all 

 for human food ; also whisky, corn oil, glucose, starch, and 

 many others ; and for stock food, gluten meal, corn hearts, 

 corn bran, and others. 



The pith of the stalk is used as a packing material in 

 the construction of warships. From the stalk cellulose is 

 manufactured. All parts of the plant are used as food for 

 live-stock. 



100. Draft on soil fertility. — A crop of 40 bushels of 

 corn and 2500 pounds of stover removes approximately 

 the following amounts of plant-food : — • 



From the above table it may be seen that every bushel of 

 grain removes about one pound of nitrogen, two fifths 

 of a pound of phosphoric acid, and about one third of a 

 pound of potash. 



These figures impress the need of the corn plant for nitro- 

 gen, which is most economically supplied in a preceding soil- 

 impreving or leguminous crop (as cowpeas), or in manure. 



It should be noticed that the stover removes about three 

 times as much potash as does the grain; and also practi- 

 cally half as much nitrogen. Hence the removal of the 

 stover greatly increases the need for nitrogen and potash 

 in the fertilizer for succeeding crops.
