these purposes, bluegrass, timothy, red clover, cowpeas and soy beans. 

 The cultivated crops alternating with these are hemp, tobacco, corn and 

 wheat.

LOUISIANA 



Many sugar planters plant corn and cowpeas after harvesting the last crop 

 of stubble cane, growing a crop of corn and cowpeas one year in three or 

 one year in four. The rice land is sown for two, or sometimes three years, then 

 devoted to cotton or allowed to grow weeds and grass, and then put in rice 

 again. On the prairies of southwestern Louisiana many fields have been 

 devoted to rice for twelve or fourteen years in succession. On a majority 

 of the larger plantations cotton is grown continuously year after year. Corn 

 is practically the only other crop grown so there is little rotation. On the 

 alluvial lands, one year in four or five cotton land is put into corn and cow- 

 peas. In the hill lands a few plant grain or cotton, two years; then corn and 

 cowpeas one year; and sometimes a crop of oats, followed by a crop of cow- 

 peas. A very desirable rotation is oats, cotton and corn, with cowpeas 

 between. The oats are harvested in May and the land put in cowpeas. 

 These are harvested in September or October and the land is fall-plowed 

 and the following year planted in cotton. The cotton is followed with corn, 

 and cowpeas sown in the corn at the last plowing. The corn is gathered 

 in September or early October and the land is plowed and sown to oats. 

 With the addition of a reasonable amount of acid phosphate this builds 

 up the land very perceptibly.

MAINE 



In many sections of the state no systematic rotation is practised. We 

 have many "patchy farms"; a man will go to the middle of the field, or to one 

 side, and plow a small area and on this plant any crop. In Aroostook County 

 a three-course rotation, consisting of potatoes, oats or wheat, and clover, 

 is followed. On the college farm, we are practising a four or five-year 

 rotation, potatoes, corn, oats, seeding with the oats to grass, and clover, 

 and allowing the land to remain in grass one or two years. This rotation 

 is frequently followed in dairy sections.

MARYLAND 



The principal crop rotations practised in this state are: Southern Maryland 

 (Tobacco section), (1) tobacco, wheat, red clover; (2) tobacco .wheat, red- 

 top and red clover. Central and eastern Maryland (dairy farming and 

 grain and hay crops), (3) corn, wheat, timothy and clover, timothy; (4) 

 corn, winter barley, timothy and clover, timothy; western Maryland (beef- 

 cattle and grain farming), (5) corn, wheat, clover; (6) corn, oats, wheat, timothy 

 and clover, timothy.
