Fall tillage as we wish to indicate, refers to the 

 work following the harvest of one crop and the 

 preparation of the land for the next crop, whether 

 it be for fall or spring planting. The first very 

 important step is to follow the harvester with the 

 disk harrow, as shown in Cut No. 21 showing 

 engine pulling harvester and tandem disk, and 

 Cut No. 22 showing horses pulling tandem disk. 

 There is no time when ample moisture means 

 more in the soil than during the hot weather 

 following the cutting of a crop of small grain in 

 July or August. This is especially true of winter 

 wheat fields. 



Many have said in the past, " What's the use 

 of disking dry ground behind the harvester? " 

 This points to the honest, but stubborn belief of 

 men who have never watched the effect of such 

 work. We have repeatedly observed the soil dry 

 at the bottom of the disked stubble ground just 

 as the disk harrow passed over reasonably close 

 to the harvester and then again, at the end of ten 

 days or two weeks, even though it was hot, dry 

 weather and no rain, and the result of the upward 

 movement of moisture by capillary attraction 

 found this same firm soil moist enough to plow 

 well. 



It is the accumulation of this moisture in this
