33 CLOVERS 



It also aids in fertilizing the soil, tliough 

 probably not quite to the same extent as white 

 clover. 



Yellow clover is indigenous to Europe. It is 

 grown to a considerable extent in pastures in certain 

 areas in Great Britain, France, Germany and other 

 countries. It has highest adaptation for climates 

 that are moist and temperate. Although this plant 

 is not extensively grown in the United States, it 

 would seem probable that it will grow at least rea- 

 sonably well in a majority of the States. The ex- 

 ceptions will be those lacking in moisture in the 

 absence of irrigation. It will grow best in those 

 that more properly lie within the clover belt ; that is, 

 in those that lie northward. It grows with much 

 vigor in Oregon and Washington west of the Cas- 

 cade Mountains. In Canada, yellow clover will 

 grow with much vigor in all areas susceptible 

 of cultivation, unless on certain of the western 

 prairies. 



Yellow clover has highest adaptation for calcare- 

 ous soils. In certain parts of England it has grown 

 so vigorously on soils rich in lime as almost to as- 

 sume the character of a troublesome weed. It will 

 grow well on all clay loam soils, and reasonably 

 well on stiff clays, the climatic conditions being suit- 

 able. It has greater power to grow on dry soils 

 than the small white variety. 



Since yellow clover is usually grown as an adjunct 

 to permanent pastures, it can scarcely be called a ro- 

 tation plant. But, like other clovers, it enriches 

 the soil, and, therefore, should be followed by crops
