of Mammoth clover plants makes them of slightly greater value as 

 a soil improver, and in addition the seed yield is usually larger. The 

 one crop of Mammoth clover is somewhat less than the two crops 

 of ordinary red clover, but may be more economical owing to the 

 greater cost of harvesting two crops of the ordinary clover. On low 

 ground the stems of Mammoth clover are apt to become somewhat 

 woody. It grows less rank on poor soils, where it is ordinarily 

 grown, rather than on the heavier soils. Furthermore, on the poorer 

 soils it is excellent as a seed-producing crop, being used in a rotation 

 of corn, grain, and clover, each one year; the Mammoth clover is 

 allowed to stand for seed and no attempt is made to utilize the hay 

 other than for returning fertility to the land. The variation in the 

 time of maturity of this clover enables it to avoid many of the insect 

 pests which greatly injure the fields of ordinary clover. This item 

 is important in reducing the injury from many of the insects 

 which play havoc with the successful production of seed of the ordi- 

 nary red clover. The seed of the Mammoth clover is slightly larger 

 than, and is recommended above, either the ordinary or alsike on 

 poor sandy lands in the North. 



Other Species; White Clover. The low-growing, shallow- 

 rooted white clover (Trifolium repens) is adapted only for pasturage, 

 as it does not attain sufficient height to be mown for hay. The seed 

 crop matures in July and August in the Northern States. Yields of 

 seed vary from 2 to 6 bushels per acre, and the price is about the 

 same per bushel as that of red clover. A 2-year rotation of barley 

 one year followed by white clover for seed the second is common 

 in central-eastern Wisconsin. Elsewhere it is usually seeded in a 

 mixture with blue grass and rarely if ever causes bloat as red clover 

 is apt to do. 



Giant White or Ladino Clover. A tall-growing variety of white 

 clover (Trifolium repens var. lata), first experimented with in this 

 country by the North Carolina Experiment Station, was procured in 

 Italy and may be imported thence in limited quantities. It grows 

 several times taller than the ordinary white clover but not so tall as 

 either the alsike or the ordinary red clover. It furnishes an excellent 

 yield of good pasturage and makes sufficient growth to be cut for 

 hay. The stems grow prostrate and only the elongated leafstalks 

 and leaves are used for hay, which is a very nutritious feed but is 

 somewhat hard to cure. 



Alsike Clover. Intermediate in general appearance between 

 the white and red clovers, and erroneously supposed to be a hybrid 

 between the two, is alsike clover (Trifolium hybridum), also called 

 Swedish clover. Alsike is especially adapted to w r et soils and also 

 to soils which are too low in humus to grow red clover to advantage. 

 Seed may be taken from the first crop, although an early clipping 

 (especially- if the spring is unusually wet) will usually result in a 

 better crop of seed. The blooms are excellent as honey producers. 

 In comparison with red clover, which lasts only two years, the alsike 

 lasts for three to five years or even longer. The seed is much smaller 

 and 4 to 8 pounds per acre is an ample seeding. The hay k some-
