Rotation 3. — -Three-year crop rotation, Catawba County, N. C, and other southern 



Piedmont areas. 



First year. Cotton. Planted in April and May; first picking in September; cover 

 crop crimson clover or rye planted; land available to plow in spring. 



Second year. Corn. Planted in April or May; peas planted in middles at last work- 

 ing of corn; seed picked; land disked and small grain planted. 



Third year. Small Grain. Peas or soy beans planted for hay or seed; land available 

 for fall and winter and early spring plowing. 



This arrangement allows approximately one-third for cotton, one- 

 third for small grain, and one-third for corn. If more than the usual 

 amount of stock is being kept this may perhaps be a more desirable 

 rotation than those already described. 



For some special cases a two-year rotation, with 50 per cent of the 

 land in cotton, may be desirable. This rotation in addition to giv- 

 ing 50 per cent of the land to cotton gives 25 per cent to small grain, 

 25 per cent to summer hay crops, and 25 per cent to corn with summer 

 legumes between the corn rows, and with the aid of the manure made 

 on the place will keep the humus content of the soil up to a fairly 

 good standard. This rotation is not recommended for land of a low 

 degree of fertility, nor for farms requiring a great deal of corn and 

 hay for live stock. 



Rotation 4. — -Two-year upland crop rotation for Catawba County, N. C, and other- 



southern Piedmont areas. 



First year. Cotton. Planted in April and May; first picking in September; one- 

 half field planted in small grain; one-half plowed in winter and spring for corn. 



Second year. Small Grain and Corn. From half of field small grain harvested in 

 June; cowpeas or soy beans for hay or seed; other half of field corn planted in 

 April or May; peas planted in middles at last working; hay harvested in Sep- 

 tember; corn and peas gathered in October and November; land available for 

 winter and spring plowing. 



Occasionally different rotations are wanted for different classes of 

 land on the farm. The farm having both uplands and bottom lands 

 should have a rotation in which cotton is by far the most important 

 crop for the higher lands and one in which preeminence is given to 

 corn for the bottom lands. 



For the upland fields, or cotton land, the suggested rotation covers 

 a period of 3 years. (Rotation 5.) 



Rotation 5. — Three-year upland crop rotation for Catawba County, N. C, and other 

 southern Piedmont areas. 



First year. Cotton. Planted in April and May; first picking in September; cover 

 crop crimson clover or rye ; land available for spring plowing. 



Second year. Cotton. Planted in April and May; first picking in September; small 

 grain planted after second picking — October. 



Third year. Small Grain. Harvested in June; cowpeas or soy beans for hay, or 

 seed; land available for fall, winter, and spring plowing.
