"Now it will be immediately perceived, that these recommendations of a practical farmer completely fulfil the conditions, which theory suggests, for making the best use of our manure, by first neutralizing the ammonia, and afterwards detaining it within the pores of a spongy sub- stance, until it is spread over the land. "The most effectual plan, however, of preventing its "* Part II p. 13D." 280 APPENDIX TO PART I. loss, would seem to be, not to wait for the slower action of carbonic acid upon... it, but to combine it directly with those acids, which form with it salts fixed at common tem- peratures. "Hence, Liebig advises the addition of sulphuric or of muriatic acid, both cheap substances, to the other materials of the dung-heap, which, forming with the ammonia pres- ent, the sulphates and muriates of that alkali, would at once prevent any loss of it by evaporation. " If these expedients be not adopted, it should at least be borne Jr mind, that unless means are taken to prevent it, the most valuable portion of the manure is constantly escaping, during exposure to air and sun, by evaporation, and also by draining off into the ground, whence, instead of a material calculated to afford a ready supply of nitro- gen to the plant, we obtain an effete mass, in which that element is in a great measure wanting, and which, there- fore, can only influence the growth of plants, by virtue of the phosphoric salts and other fixed ingredients still pres- ent in it.
