SWEET CLOVER 3O5 



that it may come to be used for purposes of soil 

 renovation. 



Soils — But little can be gleaned from American 

 sources on this subject. Notwithstanding, it may be 

 said with safety that it has greater power to grow on 

 poor, worn and hard soils than any forage plant that 

 has yet been introduced into America for economic 

 uses. 



It will probably be found true of it, as of other 

 clovers, that it will thrive best on soils that have 

 produced timber, and more especially timber of the 

 hardwood varieties. This means, therefore, that it 

 will grow well in probably all kinds of clay soils 

 and also in loam soils underlaid with clay. It has 

 high adaptation for soils abounding in lime. It 

 can be made to succeed on hard clay subsoils from 

 which the surface soil has been removed. But it 

 will also grow well on sandy soils and even on 

 gravels when a reasonable amount of moisture is 

 present. The author succeeded in growing it in 

 good form in 1897 and 1898 in a vacant lot in 

 St. Paul, from which 6 to 8 feet of surface soil had 

 been removed a short time previously. The subsoil 

 was so sandy that it would almost have answered 

 for building uses. 



This clover will probably grow with least success 

 on soils of the prairie so light in texture as to lift 

 v/ith the winds, and in which the underlying clay is 

 several feet from the surface, also in slough soils 

 that are much saturated with water. 



Since it grows vigorously on road sides, in rocky 

 waste places and even in brick yards when sown
