useless to apply the manure on frozen ground, for an ensuing rain ormelting of the snow may dissolve and carry away either in solution orsuspension most of the fertilizing ingredients. If a lawn is not mowed too late in the season and is not cleanedtoo completely of the mowed grass, it will generally provide its ownmulch for the winter very satisfactorily. Bone meal alone, especially if not very finely ground, may be usedin the late fall at the rate of five hundred pounds an acre, or twelvepounds to 1,000 square feet every year. Bone meal seems to be thebest phosphoric acid carrier for lawns. Nitrate of soda is the quickest-acting fertilizer and may be used broadcast in quantities up to five hun-dred pounds an acre each year. This quantity must be divided amongtwo or three separate applications. Both blue grass and clover willbe encouraged by the use of air-slaked lime as a winter dressing everyfour or five years, at the rate of one ton an acre. Chemical fertilizersare best applied in the spring as a top-dressing and about five hundredpounds an acre should be applied. A mixture of 5% nitrogen, 6% avail-able phosphoric acid, and 8% potash will produce good results. Equalparts of finely ground bone meal and sifted wood ashes at the rate ofone ton an acre make a good spring top-dressing. Kiln-dried sheep ma-nure may be used at the rate of one ton an acre or fifty pounds to 1,000square feet, with excellent results, with the assurance that it will notbring in weed seeds. It should be applied in early spring for thebest results. |
