5. Crops of dissjinilai" feeding habits should follow each other to 

 release the soil of excessive demands for special elements of plant 

 food. 



0. The rotation should be sso arranged that in connection with the 

 humn« produced and the farm manure the soil is kept in the best 

 mechanical condition. 



7. Rotations should be jjlanned so as ki produce the fodder for 

 stock that both in the form of milk and live stock, some imi)ortaut

 TO produce liumiiication, how to i)roduce nitrification. How to pre- 

 vent denitritication, how to presvrNe manure if it be necessary to do 

 so, how best to utilize farm manure, how and when to use lime, how 

 to make commercial fertilizer, how to determine what fertilizer our 

 crop and soils need, hoA>' it helps us to recognize the feeding capaci-

 which we mav get the best results all around. WiU not then a 

 knowledge of chemistrv be of adl^'antag•e to the farmer?
