ADAPTATION 



Strawberry clover is adapted to all the Western 

 States and to some adjacent areas, including parts 

 of western Nebraska. 



Adaptation to temperature varies with different 

 strains. Some strains are adapted to cool climates 

 in northern areas; other strains are adapted to milder 

 climates farther south. 



The degree of tolerance to high concentrations of 

 salts is influenced by temperature, by moisture con- 

 tent of the soil, and by the kind and dispersion of 

 salts. Because one or more of these conditions may 

 vary widely within a short period, it is impossible to 

 state any definite degree of salt concentration that
