=Preparing the Soil.=--The preparation of the land for alsike clover on ordinary soils is the same as for medium red clover. (See page 74.) Usually, that degree of fineness in the pulverization which best prepares the soil for the nurse crop with which alsike clover is sown, will also best prepare it for the alsike. But there may be some instances, as in strong clays, when a fine pulverization that would suffice for the needs of the nurse crop would be advantageous to the alsike. This finer pulverization can only be secured by the judicious use of the roller and the harrow. In loose-lying soils, more especially in areas where the precipitation in winter comes in the form of snow, and, therefore, does not wash the land as it does when it falls as rain, if the land on which alsike is to be sown is plowed in the fall, and only harrowed in the spring, or cultivated and harrowed when preparing it, the moisture will be better conserved than if it were plowed in the spring. When thus managed, strong clays in the area under consideration will usually have a much finer pulverization than can be obtained from spring plowing. When the preceding crop has been given clean cultivation, to plow land subsequently before sowing to alsike would bring up many weed seeds to the surface, where they would at once begin to grow. On slough lands, where water saturation is present during a portion of the year, even to the extent of appearing for a short interval over more or less of the surface, the seed may be sown without any previous preparation of the land, and in some instances successfully. In other instances it will fail should the following summer prove adverse. The stand is rendered much more certain in such instances by first burning off the grass, sowing the seed upon it, covering it more or less with the harrow and running the mower over the ground, say, twice in the season, to let in sunlight to the young plants. The grass thus mown may be left as a mulch. Pasturing, but not too early in the season, will in some instances give results equally good. In such situations the sowing should be done, and also the harrowing, before the frost has left the ground, except for a short distance from the surface, or the horses may sink too deeply when doing the work. The success is dependent in no small degree on the denseness or want of denseness of the root growth of the grass plants already covering the soil. The more dense these are, the less easy is it to obtain a stand, and the more peaty the soil immediately underneath the surface, the greater is the danger that the young plants will perish in a time of drought.
