To grow good crops of crimson clover, it is necessary that there shall be a considerable amount of plant food in the soil that is readily available. Farmyard manure when it can be spared or secured will supply the need. But the results will probably be more satisfactory where the manure has been applied to the previous crop, as, for instance, to potatoes or corn, and for the reason, probably, that in the relatively dry season at which the seed of this plant is sown, the residue of the manure still in the soil is more readily available than freshly applied manure would be. Good crops have been grown on land thus manured, when at the same time seed sown on land under similar conditions and similar in other respects failed to give satisfactory yields. In a majority of instances farmyard manure cannot be spared for such a use. When it cannot, if necessary, commercial fertilizers may be applied. Those rich in phosphoric acid and potash are usually most needed, but sometimes nitrogen also is necessary. When nitrogen is used, it may be best applied on the growing crop and while it is young. Phosphoric acid and potash may be fitly applied when the land is being prepared, and in a way that will incorporate them with the surface soil. These may be used in the form of wood ashes, bone meal, Thomas' slag, Kainit, sulphate or muriate of potash, South Carolina rock and acid phosphate. Acid phosphate and muriate of potash stand high in favor with some growers when applied in the proportions of 9 and 1 parts and at the rate of, say, 200 pounds more or less per acre. =Sowing.=--The date for sowing crimson clover would seem to depend more upon latitude than upon any other influence. North of the Ohio River it should seldom be sown later than September 1st, lest the growth of the plants should not be strong enough to endure the winter weather. Nor should it be sown earlier than July 1st, lest the plants should reach the blooming stage without having made a sufficient growth, an objection which applies to sowing earlier than July 1st in any part of the United States. All things considered, August is the most favorable month for sowing the seed north of the Ohio and Potomac rivers. In the South, sowing at a later period is preferable. In the latitude of Tennessee, September would usually prove more suitable for sowing than an earlier date, and near the Gulf, October. But it may be sown earlier and later in these respective latitudes. It is a good time to sow the seed in much of the South when the autumn rains begin to come, and the same is true of the Puget Sound country.
