forage crops and grazing them off is a good method of improving 
soils lacking in organic matter. 
Kinds of crops: (a) For the cotton belt Bermuda, bur clover, 
white clover and Lespedeza make good permanent pastures. These 
should be supplemented by small grains and rape for winter, crimson 
clover and vetch for spring, cowpeas (fig. 9) and sorghum for summer, 
corn with soy beans, velvet beans or peanuts for fall. (6) For the 
Central and Middle Atlantic States, including the bluegrass region, 
bluegrass should be used largely for permanent pasture. It should 
be supplemented by rye (fig. 10) for winter, rape (fig. 11) for spring, 
red clover for spring and summer, corn with soy beans and rape for

fall, (c) For the Northern and Eastern States bluegrass or redtop 
provides permanent pasture. Supplementary grazing should be 
furnished by oats and peas for spring, rape and red clover for sum- 
mer, and early field corn for fall, (d) For the West grazing is fur- 
nished by alfalfa and corn. Corn should be "hogged down." 
Study questions. — What is the value of the permanent pasture? 
Why are supplementary crops necessary? What grazing crops are 
used in the community for permanent hog pastures ? What supple- 
mentary grazing crops are grown? Make out a list of seasonal 
succession crops for supplementary grazing adapted to the com- 
munity. Compare this fist with the crops suggested for your sec- 
tion of the country.
