When the mammoth and medium varieties of clover are sown for hay with one or two kinds of grass only, it is not common to sow more than 6 to 8 pounds of either per acre. The maximum amount of the seed of the alsike required when thus sown with grasses may be set down at 5 pounds per acre. These three varieties are chiefly used for such mixtures. With more varieties of grass in the mixtures, the quantities of clover seed used will decrease. When clovers are sown with mixtures intended for permanent pastures, it would not be possible to name the amounts of seed to sow without knowing the grasses used also, but it may be said that, as a rule, in those mixtures, the clovers combined seldom form more than one-third of the seed used. The seeds of some varieties of clover are less than one-third of the size of other varieties. This, therefore, affects proportionately, or at least approximately so, the amounts of seed required. For instance, while it might be proper to sow 12 pounds of medium or mammoth clover to accomplish a certain result, less than one-third of the quantity of the small white variety would suffice for the same end. The influences of climate and soil on the quantities of seed required are various, so various that to consider them fully here would unduly prolong the discussion. But it may be said that the harder the conditions in both respects, the more the quantity of seed required and _vice versa_. =Pasturing.=--When clover seed is sown in nurse crops that are matured before being harvested, the pasturing of the stand secured the autumn following is usually to be avoided. Removing the covering which the plants have provided for themselves is against their passing through the winter in the best form. In some instances the injury proves so serious as to result in a loss of all, or nearly all, the plants. The colder the winters, the less the normal snowfall and the more the deficiency of moisture, the greater is the hazard. But in some instances so great is the growth of the clover plants that not to graze them down in part at least would incur the danger of smothering many of the plants, especially in regions where the snowfall is at all considerable. But when the seed is sown alone or in mixtures of grain and even of other grasses in the spring, grazing the same season will have the effect of strengthening the plants. This result is due chiefly to the removal of the shade that weeds and other plants would furnish were they not thus eaten down, but it is also due in part to the larger share of soil moisture that is thus left for the clover plants. Pasturing clover sown thus should be avoided when the ground is so wet as to poach or become impact in consequence. Unless on light, spongy soils which readily lose their moisture, such grazing should not begin until the plants have made considerable growth, nor should it be too close, or root development in the pastures will be hindered.
