secured. The following rotations are recommended as Avell adapted for 

 conditions prevailing in the county : 



First Year — Corn with soy beans and cowpeas drilled in the row at 

 planting or before the first cultivation. They may be broadcasted 

 just before the last cultivation if this is more desirable. 



Second Year — Wheat or oats, followed by red clover, spring seeding. 



Third Year — Red clover. 



This is a very short rotation and is admirably adapted for use by 

 the grain farmers of the county. It will be essential to use lime where 

 red clover is seeded in order to be sure of success. The corn stover and 

 wheat straw from such a rotation should be plowed in or be fed to 

 stock and the manure carefully saved and returned to the soil. The 

 soybeans or cowpeas and the last crop of red clover in the third year 

 should be turned in to add to the organic matter and nitrogen supply 

 of the soil. In starting this rotation on the average soils of the 

 county use the fertilizer mixture given above for leguminous crops. 

 If available, farm manure may be used with acid phosphate. In that 

 case, if the application is fairly liberal the necessity for applying ni- 

 trogen in the fertilizer mixture will be materially reduced or entirely 

 done away with. During the first year wheat or oats are grown on 

 the land they should receive the treatment indicated above for corn. 

 In addition to the acid phosphate, it would be well to apply 200 to 400 

 pounds of rock phosphate, as this fertilizer is for both the wheat and 

 clover crop that is below. An application of 600 to 800 pounds of rock 

 phosphate per acre to a good crop of red clover at the time or just be- 

 fore it is turned into the soil in the field might furnish much of the 

 phosphoric acid required by the crops of the second period of the rota- 

 tion. Within a comparatively short time enough nitrogen should be 

 furnished by the soybeans or cowpeas, the clover and the roughage or 

 stable manure, if the crops are good and the manure saved and applied 

 back on the land or plowed directly into the soil after maturity. The 

 application of rock phosphate and lime should be made every four to 

 five years. Live-stock farming in connection with this rotation might 

 help in improving the j^roductivity of these soils if the manure is prop- 

 erly saved and applied back on the soil, 



FOUR-YEAR ROTATIONS. 



A good four-year rotation is the same as the above, with oats and 

 soybeans or cowpeas following" the corn the second year. 



Other four-year rotations which could be adopted in this county 

 are: 



First Year — Corn. 



Second Year — Crimson clover and cowpeas or soybeans. 



Third Year — Wheat and oats, red clover. 



Fourth Year — Ked clover.
