While sand lucerne has higher adaptation than common alfalfa for sandy and gravelly soils, it does not follow that it has equal adaptation for being grown on ordinary alfalfa soils. No advantage, however, would result from growing sand lucerne where common alfalfa will grow equally well, as it is not superior to the latter as a food, if, indeed, it is equal to the same, and there would be a distinct disadvantage in the greater cost of the seed of sand lucerne. Sand lucerne is not any more a rotation plant than the common variety. In fact, it is even less so, since it would not be practicable to introduce it into short rotations when grown in northerly latitudes, as it does not reach a maximum growth for several years after the seed has been sown. But in mild latitudes, it may be found practicable to introduce it into short rotations, like other alfalfa (see page 135), and on land that is too sandy to grow the common variety in the best form. Much of what has been said about the preparation of the soil for common alfalfa will equally apply to the preparation of the same for sand lucerne. (See page 137.) But when the latter is sown on sandy or gravelly land, a moist condition of the seed-bed at the time of sowing is even more important than when sowing common alfalfa under ordinary conditions. The same methods of sowing the seed will be in order as are suitable for sowing common alfalfa in any particular locality. (See page 147.) This will mean that in Northern areas sand lucerne can best be sown in the spring and as early as the danger from frost is over, that the plants may get as much benefit as possible from the moisture in the soil before dry weather begins. It will also mean that if sown southward in the autumn, it may in some instances be necessary to wait longer for the sandy soils on which the seed is sown to become sufficiently moist to sprout the seed than for such a condition in soils on which common alfalfa is usually sown. The amounts of seed to sow will also be practically the same. (See page 152.) The adaptation of sand lucerne for providing pasture is as high, if not, indeed, higher, than that of common alfalfa, since it is said that it has less tendency to produce bloat in cattle and sheep, and it is not so easily destroyed, at least in Northern areas, by grazing. In providing pasture, its higher adaptation is in furnishing the same for cattle, swine and horses.
