early and late water is assumed. First year — Plat i , 

 oats ; plat 2, wheat ; plat 3, potatoes or corn ; plat 4, 

 potatoes or corn. Second year — Plat i, oats, seed to 

 alfalfa; plat 2, potatoes, plow deep; plat 3, wheat; 

 plat 4, wheat. Third year — Plat i , alfalfa ; plat 2 , 

 wheat; plat 3, wheat, seed to alfalfa; plat 4, potatoes, 

 plow deep. Fourth year — Plat i, turn under alfalfa 

 and plant to potatoes ; plat 2, wheat, seed to alfalfa ; 

 plat 3, alfalfa ; plat 4, oats or wheat. After the fourth 

 year raise two crops of potatoes after alfalfa. 



Wheat may follow wheat once. Wheat should 

 never follow oats. Oats had better follow wheat than 

 oats. Alfalfa should be seeded in the spring with 

 wheat or oats and should remain two years after the 

 seeding year. Potatoes should follow alfalfa and may 

 follow potatoes once. The following shows another 

 rotation worked out on this plan, with the exception 

 that alfalfa does not always remain on the ground two 

 years after the planting : First year — Plat i , wheat ; 

 plat 2, wheat ; plat 3, oats ; plat 4, oats or barley. 

 Second year — Plat i, wheat, seed to alfalfa; plat 2, 

 potatoes, plow deep; plat 3, potatoes, plow deep ; plat 

 4, oats, seed to alfalfa. Third year — Plat i, alfalfa ; 

 plat 2, wheat, seed to alfalfa; plat 3, potatoes ; plat 4, 

 alfalfa. Fourth year — Plat i, potatoes; plat 2, alfalfa; 

 plat 3, wheat, seed to alfalfa; plat 4, potatoes. Fifth 

 year — Plat i, potatoes; plat 2, potatoes ; plat 3, alfalfa; 

 plat 4, wheat. Sixth year — Plat i, wheat, seed to 

 alfalfa; plat 2, potatoes; plat 3, alfalfa; plat 4, wheat, 

 seed to alfalfa. Seventh year — Plat i, alfalfa ; plat 2,
