4 KXTKSMU'S ClKCULAt NO. 24 [Jul ROTATIONS FOR ( KNTRAL ILLINOIS In the most important corn-producing section of the state H a ,.,.,„,.„! Illinois, a five-year rotation consisting of two y(,a'rs'f [ D, one year of oats, one year of clover or other legume crop Z year of wheat would be fairly satisfactory to meet the ,,r'(.s,nt agency. This rotation iwitli 20 f„ ,,, ,,t ,,f wheat), would pro . e just about tliree times the average proportion of wheat now •rrown in the state. In entr . an even greater increase over the proportions grown at the present time. A four-year rotation consisting of one year of corn, one year of oats, one year of clover or other legume crop, and one year of wheat would also be satisfactory for this section, especially for grain farmers. This rotation would still furl her increase the proportion of wheat. Both these rotations are coming into somewhat common use among the best farmers in the corn-belt section of the state. Both make possible a very satisfactory distribution of man and horse labor during the cropping season, and both permit the seeding of sweet clover in the wheat as a cover crop to be plowed under for corn. Farmers in central Illinois should plan to grow from one-fifth to one-fourth of their improved land in wheat. ROTATIONS FOB SOUTHERN ILLINOIS In southern Illinois, which grows a major part of the wheat produced in the state, the proportion of wheat grown may be still further increased. Rotations containing from one-fourth to one-third of wheat may be used to good advantage in this section. The fouryear rotation consisting of corn, oats, clover, and wheat is usually a satisfactory one on well-limed land. By seeding wheat in the standing corn, or after the corn is cut for silage or shocked in the field, a three-vcar rotation <VP /^~_ 1 x _ J clover may he used v mi,«ftt. and luutuuns are: corn, cowpeas corn, eowtipas r>r omr)<nn«n J treated WHEAT AND GREATER PROFITS gested, may have to be varied for individual farmers.
