CROP ROTATIONS 



clover will make enough growth to furnish some pasture that 

 season. 



Third year, clover hay one or two cuttings, and pasture through 

 the following winter. 



In the growing of alfalfa a rotation may be followed. Corn 

 followed by a cover crop may be used the first year. In the spring 

 oats and peas are sown and the crop cut for hay in the blossom 

 stage. The 'soil is prepared immediately for alfalfa and kept

 then occupy the ground for three or four years, or as long as the 

 stand remains good. It is then plowed up for corn. 



Long rotation courses are sometimes followed in regions 

 where a single crop is desired for market. This may be the case 

 where cotton is to be grown as frequently as possible without 

 detriment to the soil. In the corn belt and in wheat growing 

 states long rotations are sometimes adopted.
