humus by green manure crops such as rye and legumes; 

 deep plowing followed immediately by sub-packing the soil 

 (by using the disk set nearly straight or, in light soils, by 

 using a sub-surface packer); and thorough preparation of 

 the seed bed. The success of these measures is seen by 

 comparing the average yield of 14.5 bushels per acre for the 

 entire state of California with 33.7 to 57.3 bushels on sandy 

 soils, and 43 to 48 bushels on heavy soils, where this practice 

 was followed. 



In the Corn Belt wheat is generally a secondary crop. It 

 is used in rotation, in part, to provide a cash crop, and in 

 part, to secure a stand of clover. It is a common practice 

 to sow wheat in the early fall between rows of corn. This 

 method saves labor. It gives good results when a good mulch, 

 a fine seed bed and freedom from weeds have been secured 

 by thorough cultivation during the growing season. Because 

 the maturing corn crop removes plant food from the soil a 

 light application of a complete fertilizer will be needed to 

 give the young wheat plants a good -start. Instead of a light 

 application of a complete fertilizer many wheat growers prefer 

 a heavy application of acid phosphate alone. This practice 

 is based upon the fact that wheat requires for a high yield a 

 liberal supply of phosphorus. The place of rotation will 

 depend upon the cropping plan for the farm. It is valuable 

 as a nurse crop for clover, affording an easy way to secure a 

 good stand. The straw is of considerable value for feeding 

 live stock. At the same time it will make some return for 

 the use of the land. Its relation to other crops should be 

 such that the care of the wheat will not interfere with other 

 work during harvest time. 



Seed. The first consideration is to select the kind and 

 variety of wheat best adapted to the region in which it is
