ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 



same county have been analyzed and the 

 results presented are computed from the 

 averages of these analyses. In many 

 counties of the state several distinct 

 types of soil are to be found, sometimes 

 lying In fairly distinct areas of consid- 

 erable size, but frequently more or less 

 intermingled or overlapping. In each 



county, those types which are thought 

 to be most representative and likely to be 

 most easily recognized, or most common- 

 ly met with, are included in the tables. 

 Information as to the composition of 

 types not included in the tables may gen- 

 erally be obtained by correspondence

Practical Ratines of Soil 



While the composition of the soil is 

 no* necessarily a certain index of its 

 crop-producing ability, a knowledge of its 

 plant food content makes it possible to 



compare it with other soils of known 

 fertility, and so get a fairly accurate idea 

 of its probable relative grade or value 

 for agricultural purposes. As a result of 

 long-continued study of this subject the
