illustrations show that a much more favorable 

 condition exists and a greater amount of plant 

 food is available, therefore, a still greater stooling 

 and growth. Study well the specific design of 

 Cuts No. 10, and No. 11, and grasp what they really 

 represent. No. 10 illustrates the effect of an ideal 

 soil condition on growth, and No. 11 gives a 

 contrast of the influence on growth of roots and 

 plants of both ideal and the poor fitting of the seed 

 bed. 



CHAPTER X 



SUMMER TILLING FOR WHEAT 



Under the heading of "Preparation Before Seed- 

 ing", we have discussed at some length summer 

 tilling in a broad sense, but in this chapter we 

 wish to cover it with relation to winter wheat and 

 much more in detail. 



Summer tilling is handling the field from early 

 spring to time of fall planting in a manner not 

 only to gather and store the rain water as it comes, 

 but to improve the soil and bring it up to a high 

 state of physical condition for increasing the 

 available plant food. 



As first outlined years ago, summer tilling was 

 only intended for wheat growing and more 

 especially winter wheat. But we have found that 

 similar principles, with some modifications, and 

 previously referred to as Spring Tillage, are ad- 

 mirably adapted to the plan of growing corn, 

 cane, broom, millet, potatoes and similar crops,
