corn, wheat or oats, clover. The four-course corn, oats, wheat, clover, is 

 more or less used in central Indiana; also corn, wheat or oats, clover and 

 grass two years. In southern Indiana we sometimes find a two-course 

 wheat and clover rotation. For general purposes we consider the three- 

 course rotation best. Most of our farmers claim that they can get a better 

 stand of clover in wheat than in oats. Occasionally we find a four-course 

 rotation, consisting of corn, corn, small grain, clover.

Corn is the "money-crop" of Iowa and it is desired to raise as many crops 

 of corn as possible. Clover has thus far been found the most satisfactory 

 leguminous crop for a rotation in this state. In the southern part of the 

 state a common rotation is corn two years; wheat one year; clover one year. 

 This may be extended into a five-year rotation by allowing the land to remain 

 in clover and timothy for two years. Another rotation, practised less 

 extensively, is corn one or two years; oats one year; wheat one year; clover 

 and timothy, one or two years. In the northern portion of Iowa, where 

 winter wheat has not been as successfully grown, the rotation most extensively 

 practised is corn two years; oats one year; clover one year. In many cases 

 it is necessary to sow a catch crop of cowpeas in order to include a leguminous 

 crop in this rotation. Winter wheat is superior to oats as a nurse crop for 

 clover, and is being included in rotations wherever it can be successfully 

 grown.

Less than 10 per cent., and perhaps less than 5 per cent., of Kansas farmers 

 practise rotation of crops. The three main crops are corn, wheat and 

 alfalfa. Many fields can be found in some sections upon which wheat has 

 been grown almost continuously from twenty to thirty years. The same 

 may be said of corn-growing, especially in the eastern part of the state. 

 Alfalfa is often left on the fields for many years. The size of the farms 

 is such that the farmers must resort largely to wheat culture, as it would be 

 impossible to farm them thoroughly with several crops with the small amount 

 of nelp. In most of the wheat sections the farmers grow some corn, kaffir 

 corn or sorghum, but do not have any definite rotation. Two rotations we 

 are suggesting are: (1) Alfalfa, four years; corn, two years; wheat, one year; 

 and alternating two years of corn with one of wheat for nine years more 

 before seeding again to alfalfa. (2) Grasses and clover, three years; corn, 

 two years; spring grain, one year; wheat with catch crops, one year, repeating 

 the latter three twice before seeding to grass and clover in wheat.

There is no very generally adopted rotation, but as the fanners understand 

 the importance of getting humus in the soil, and of using clover or some 

 related plant in order to increase the nitrogen, they generally employ for
