has been about 600,000,000 pounds of rough rice annually. 

 In the early years of the twentieth century, a third rice- 

 growing area has been developed in the prairies in the 

 southeastern part of Arkansas. In the United States the 

 area devoted to rice increased threefold in the sixteen 

 years ending in 1905, the area reported that year being 

 nearly half a million acres, and the yield more than 

 13,600,000 bushels. 



197. Composition. Rice is a very starchy grain. A 

 human diet made up largely of this cereal should also 

 include foods rich in nitrogen, such as seeds of cowpeas 

 and other legumes, fish, lean meat, eggs, or milk. The 

 composition of rice and its products is shown below : 1 - 



McDonnell's analyses 2 indicate that a rice crop of 35 

 bushels (nearly 9 bags) and 1800 pounds of ripe straw 

 removes from the soil, in round numbers, 



12 pounds of phosphoric acid, 

 29 pounds of nitrogen, 

 35 pounds of potash.
