Crops and Cropping 171 



the fertility of other people's land in this way, and these 

 must get what their land needs in some other way. The 

 most ready way is through the use of commercial fer- 

 tiUzers. 



There has been so much experimentation with com- 

 mercial fertilizers on various crops by the experiment 

 stations all over the country that farmers in many sections 

 have imbibed the notion that for every crop grown they 

 need a specially adapted fertilizer mixture. 



In the discussion of the various crops we will endeavor 

 to show what we consider the proper use of these fertilizers 

 in the growth of the money crops through their use more 

 directly on the crops that feed the stock, feed the land, 

 and increase the humus of the soil. In order to treat 

 more fully of the crops that do these things we will follow 

 the chapters on the leading farm crops with one especially 

 devoted to the various legume crops that are so important 

 in the improvement of the soil, for, as we have often 

 stated, in our opinion the farmer of the future must be a 

 legume farmer, and must depend more and more on this 

 class of plants for feeding his stock and feeding his soil.
