CAMPBELL'S SOIL CULTURE MANUAL 53 



putting your field in ideal condition to plow, and by using 

 reasonable caution to harrow or again disk in case of 

 excessive heavy rains you can plow at any time. 



CONSIDER SOIL CONDITIONS. 



The proper depth of plowing, as we have previously 

 attempted to show, must be governed very largely by the 

 condition of the soil, the time of year that the plowing is 

 done, the time it is to be seeded or planted, and the kind 

 of tools you have for the after work. 



Take the average prairie soil, especially if level with 

 a sand loam formation : I advise plowing fully seven inches 

 deep if to be seeded or planted soon after. But to do this 

 and anticipate a fair crop, the soil must be moist and not 

 wet. The surface must be thoroughly disked before 

 plowing, and the sub-surface packer must follow close 

 to the plow. The plowing done before noon should be 

 packed before going to dinner, and that done in the after- 

 noon packed before leaving the field at night, and then 

 follow with the harrow to get the surface in good condi- 

 tion before the clods get too dry. 



In case of early fall plowing, for spring crops and 

 moist soil, if you have sufficient team, it will be found 

 profitable to plow eight inches deep, following with a 

 packer and harrow as above mentioned. If you have no 

 sub-surface packer, beg, buy or borrow one. If you have 

 no packer, I would not advise plowing over fiver inches 

 deep, and use the common harrow with teeth slightly 

 slanting and weighted, the object being to pulverize and 

 firm the under portion of the furrow. But don't figure 

 on getting the same results from the five inch plowing 

 thus fitted. These observations are very important. 



EVEN FURROW SLICES. 



Much care and attention should be given to the furrow
