EXERCISE 25. THE PRODUCTION OF CORN IN THE 

 UNITED STATES 



Equipment: Yearbook of the United States Depart- 

 ment of Agriculture. * 



Method: From the Yearbook obtain the figures for 

 the production of corn in each State of the United States. 

 Represent the geographical distribution of the areas of 

 large production on the accompanying map by the use of 

 appropriate shadings. Those States which produce more 

 than 100 million bushels should be shaded black; those 

 producing more than 50 million and less than 100 million 

 a lighter shade; and those producing less than 50 million 

 left unshaded. 



Discussion : Climatic and soil conditions determine the 

 distribution of the crops in the United States. The greater 

 part of the corn grown in this country is produced in seven 

 or eight States of the Middle West, which are known as 

 the corn-belt States. Wheat is more widely distributed, 

 while oats are confined largely to the North Central States. 



The United States produces about four-fifths of the 

 world's corn crop. 



The corn belt states of this country appear to have the 

 best combination of sunshine, temperature, rainfall and 

 soils for the production of corn. Water is undoubtedly 

 the most important factor in the successful culture of corn. 

 A study of corn yields in connection with the records of the 

 Weather Bureau has brought out the fact that there is a
