One hundred pounds per acre is one pound for 48 square yards, a strip, say, one yard wide and 48 yards long. It may be necessary to repeat the experiment several years, before we can be sure what will give the best results; but we shall learn much that will help even during the first year. In mixing fertilizers, care must be taken not to mix those which injure one another; thus nitrate of soda and muriate of potash, both take up moisture from the air quite readily, and when mixed with other substances are liable to make the whole mass pasty, or even to run together and bake in the bag; these should be mixed but a short time before they are to be applied. Nitrate of soda and acid phosphate, when they are mixed and allowed to stand, become damp and act chemically upon each other, and the result is loss of fertilizer elements into the air; the same is true when basic slag and sulphate of ammonia are mixed together. We are frequently advised to apply fertilizers to the crop while it is growing. Nitrate of soda is generally used in this way, and to aid in spreading it, it is often mixed with acid phosphate. Now both of these substances, as well as muriate and sulphate of potash, are likely to burn the foliage of plants with which they come in contact; hence, broadcasting these over growing plants on a damp morning is liable to do serious injury to the foliage; it is safer to apply them with a drill.
