CAMPBELL'S SOIL CULTURE MANUAL 57 



after heavy rains. If you can't loosen it with any other 

 tool, disk it. Watch, and so far as possible, harrow when 

 the surface is just moist. This will prevent the loss of 

 any moisture, holding it as far as it may be possible beneath 

 the blanket, and in case of heavy rain harrow again. With 

 this blanket properly provided during June and July the 

 sod itself will not only be found to be well rotted but the 

 top of the subsoil to a depth of one to three inches also. 

 In August, or as soon as the soil beneath the blanket is 

 rotted, it should be plowed again, this time with the 

 stirring or stubble plow, cutting about two and a half 

 inches deeper and following with the sub-surface packer, 

 the same as outlined for ordinary stubble plowing. The 

 harrowing should be very thorough. 



If care has been taken to conserve the rain waters 

 and the work well done, this ground may be planted to 

 fall wheat or to spring crops the following spring, after 

 which it should be treated the same as old ground, except 

 to run the plow two inches deeper the next time. 



There is no economy, but on the other hand, great 

 waste, in trying to economize or minimize the amount 

 of labor required to thoroughly prepare the soil for the 

 sowing or planting of grain, for the work of thorough 

 preparation is easily and quickly done, and when once 

 done a successful harvest is assured.
