Trifolium hybridian alsike clover Clovers have long been recognized as capable of increasing soil fertility. These plants are able to increase the nitrogen content of the soil from the rout tuber- cles which they bear. The mechanical action of the Iong, deep rout systems of clovers also improves the tilth of the soil, These roots penetrate deeply into the subsoil making plant food, which is inaccessible to most other plants. Several species of clovers have been used successfully in range reseeding pro- jects throughout the west, They produce an abundance of viable seed which ger- minate well even when several years old. Seeds stored for 9 years had a germina- tion percentage of 71.6 percent. Alsike clover (T. hybrid um}, a perennial introduced from Europe, escaped from cultivation and is now found growing along roads, streams, and roe aduws in the mountains. It prefers moist soils and will thrive on poorly drained lands or • even heavy soils. This clover is not usually grown alone for hay because of its decumbent, spreading habit, but is usually cultivated in mixture with such grasses as timothy and red top. Alsike clover, although not as palatable as cer- tain other species, is never-the-less highly nutritious and apparently, does not cause bloat as readily as do some other types. (U.S. Forest Service, 1937}. Trifolium repe white clover White clover (T. re pens), a perennial with creeping stems which root at the joints was introduced from Europe but now occurs naturally on Fairly moist soils of the mountain ranges at medium to high elevations. It withstands greater temp- erature extremes than either red or alsike clover and is suited to rather cool, moist regions being quite tolerant to shade. This clover is relished highly by all livestock. It is extremely nutritious, withstands tr~r+pling well, and is 3-136 REVISED FE8 1 3 '87
