APPENDIX 407 



FLORIDA 



There is little or no systematic rotation practised. In the northern part 

 of the state, where corn and cotton are grown, they follow corn with cotton 

 and sow cowpeas in the corn, or a row of peanuts between the rows of corn. 

 Farther south where velvet beans are grown and used for fattening cattle 

 a rotation is: corn the first year, velvet beans the second year, and the velvet 

 beans are pastured off during winter and the ground is again put in corn. 

 In the vegetable section of the state, no rotation is practised unless it is 

 forced by plant diseases which can be killed only by rotation.

IDAHO 



There is little systematic rotation of crops here. A few farmers rotate 

 grain with such crops as corn, potatoes, and beans. In some irrigated 

 sections grain is rotated with sugar beets. In older irrigated sections an 

 effort is being made now to rotate grain with alfalfa. Our practice at the 

 Station is a five-year rotation: Two years of grass, one of corn, one of wheat, 

 and one of oats or barley.

ILLINOIS 



Some crop rotations which are being practised to some extent in this state 

 are: 



THREE- YEAR ROTATION 



First year, wheat, followed by cowpeas or soy beans as catch crop; second 

 year, corn, with cowpeas or soy beans as catch crop; third year, cowpeas 

 or soy beans (to be followed by wheat). All crops except the wheat should 

 be fed or pastured or used as bedding and all manure returned to the land. 

 If the corn crop is cut and shocked, then a three-year rotation of corn, wheat, 

 and clover is a good one. 



FOUR- YEAH ROTATION 



First year, corn, with cowpeas or soy beans as catch crop; second year, cow- 

 peas or soy beans ; third year, wheat (with clover to be seeded in spring) ; 

 fourth year, clover. 



If well filled, the second crop of clover should be harvested for seed. All 

 other crops, excepting wheat and possibly cowpea or soy bean seed, should 

 be fed and the manure returned to the land. 



FIVE-YEAR ROTATION 



This may be the same as the four-year rotation except that timothy may 

 be seeded with clover and the land pastured the fifth year.

INDIANA 



Corn is our principal crop practically all over the state, and forms the basis 

 of every rotation, as it is generally desired to bring in corn as often as possible. 

 The prevailing rotation, whenever any system is followed, is the three-course
