Clovers and How to Grow Them

by Thomas Shaw

Sowing.—White clover is sown by much the same methods as the medium red variety. (See [page 75].) But it will stand more hardship than the other variety; hence, it may be sown earlier. This means that it may be sown in northerly latitudes any time, from the melting of the winter snows until early summer, and in southern latitudes almost any season, except during the hot summer months. In either latitude, however, the early spring is usually the most suitable season for sowing.

The seed may be sown by hand, by hand machines, or by the seeder attachment of grain drills. It is more commonly sown along with other clovers and grasses, and the methods of sowing these will also be suitable for the sowing of white clover. (See [page 18].) But when the seed is sown alone, as for producing seed crops, the nurse crop need not of necessity be sown thinly, from the fear that the young plants should be smothered by an undue density of shade.

There is no mixture of clovers and grasses grown for pasture to which this plant may not be added with profit, providing the seed is not already in the land in sufficient supply. But it is seldom sown with either clovers or grasses, or with these combined, for the production of hay. It is the judgment of the author, however, that in localities which have special adaptation for the growth of this plant, it should render excellent service in providing hay for sheep, if sown along with alsike clover, and a little timothy; the latter being sown mainly to support the clovers so that they will not lodge. The white clover would furnish hay considerably finer even than the alsike; hence, such hay should be peculiarly adapted to the needs of sheep. Some authorities object to the presence of white clover in hay intended for horses or cattle, lest it should induce in them more or less salivation. The author leans to the opinion that in cured hay injury from the source named will in no instance prove serious, owing to the small amount, relatively, of white clover in average hay crops.

The amount of seed to sow will vary with such conditions as soil, climate and the nature of the pasture, but in any event it need not be large. The seeds of white clover are small, considerably smaller than those of alsike. For ordinary grazing along with other grasses, or grasses and clovers, it will seldom be necessary to sow more than 1 pound of seed per acre. Sometimes a less quantity will suffice, as when there is more or less of seed in the land, and, as already intimated, because of the store of seed in the land in many instances, it is not necessary to sow it at all. Especially is this true of sections which have been tilled for some time. When sown with alsike clover to provide hay, 2 pounds of seed per acre would be a maximum amount, and 4 pounds when sown alone to provide seed.

When sown in newly cleared forest lands or on prairie sod, the methods to be followed will depend upon circumstances. More commonly when thus sown the seed is not covered artificially; consequently, much of it in dry seasons may not grow. The plan, therefore, of sowing small amounts of the seed on such lands two years in succession would be safer than to sow twice the amount of the same in one year. In time this clover would find its way into such areas. It comes through such agencies as birds, hay fed to teams engaged in lumbering, and the overflow of streams; and as soon as it gets a foothold its distribution is further accelerated by the droppings of cattle which contain the seeds, and by the winds.

The power of this plant to increase is simply wonderful. This is owing to: 1. The relatively large number of seedheads produced from the plants. 2. The power which these have to multiply by means of rootlets from the incumbent stems, which fasten into the soil. 3. The prolonged season during which the heads form. 4. The habit of growth in many of the heads, because of which they are not grazed off. 5. The strong vitality of the seed. And 6. The great hardihood of the plants.

Pasturing.—White clover ranks next to blue grass as a pasture plant within the area of its adaptation (see [page 261]), when its productiveness, continuity in growth, ability to remain in the land, palatability and nutritive properties are considered together. In palatability it ranks as medium only. In the early part of the season while it is still tender and juicy, it will be eaten by stock with avidity, but as the seed-maturing season is approached, it is not so highly relished. In nutrition it ranks higher than medium red clover. It does not make much of a showing in the early part of the season, but in favorable seasons, about the time that blue grass begins to fail, it grows rapidly and furnishes much pasture.

It is pre-eminently the complement of a blue-grass pasture. When these grow together, the two will furnish grazing in a moist year through all the season of grazing. Both have the property of retaining their hold indefinitely in many soils and of soon making a sward on the same without being re-sown, when the cultivation of the ground ceases. The blue grass grows quickly quite early and late in the season, and the clover grows likewise during much of the summer. As the older plants of the clover fail, fresh ones appear, and the blue grass feeds on the former in their decay. They thus furnish humus and nitrogen for the sustenance of the blue grass.

But much moisture is necessary in order to insure good blue grass pastures, and they are more luxuriant when the moisture comes early in the season, rather than when the plants are nearing the season of bloom. To such an extent is white clover influenced in growth by such weather, that in some seasons it will abound in certain pastures, while in others it will scarcely appear in the same. Those favorable seasons are frequently spoken of as being "white-clover years."

While this plant furnishes good grazing for all kinds of domestic animals kept upon the farm, as a pasture for horses and mules, there is the objection to it that it will in a considerable degree so salivate them that much "slobbering" follows. This is sometimes produced to such an extent as to be seriously harmful. The trouble from this cause increases as the seed-forming season is approached. It has been known thus to salivate cattle, but the danger of injury to them from this source is slight. These injurious results to horses will be obviated in proportion as the other grasses are allowed to grow up amid the clover; in other words, in proportion as the pasture is not grazed closely early in the season. The animals which then graze on these pastures must take other food with the clover.
