A propos du livre

Présentation de l'éditeur

That an increase of solubility in bones and other phosphates would be attended by an increased productive power in the crop, was the idea of Liebig. This great chemist, in 1840, recommended, in lieu of bones, the use of the substance long well known to chemists as the acid or super-phosphate of lime, which is producible from bones and other phosphates by the action of sulphuric acid. Practice has since shown the great advantage of Liebig ssuggestion. The introduction of the dung of birds and other animals, under the name of GUANO ;and the discovery, in Suffolk and other counties, of immense quantities of fossil bones, and other animal remains, known as COPROLITES ,have followed quickly upon each other, and there can be no doubt that by their means an entire revolution will be made in the practice of A griculture. The concentrated character of most of the genuine artificial manures, particularly adapts them for use in the mountainous and hilly districts of our country, where the carriage of ordinary manure is both difficult and expensive. One waggon may now easily carry enough manure for 15 or 20 acres of turnips. Formerly 15 or 0loads were required for a single acre. Of all the artificial manures, Peruvian Guano is perhaps not only the most concentrated, but is, from its composition, adapted to the greatest variety of crops. The chief mineral constituents of plants lime, magnesia, potash, soda, chlorine, sulphuric acid and phosphoric acid, (the latter the most important) are found in Guano. Nitrogen, the most valuable constituent of manures, is found in Peruvian Guano in great abundance, and in a condition well adapted for vegetation.
