Seite 85 - ... and in this state, may be used in the same manner as rape-cake, and delivered into the furrow with the seed. The Chinese, who have more practical knowledge of the use and application of manures than any other people existing, mix their night-soil with one third of its weight of fat marl, make it into cakes, and dry it by exposure to the sun. These cakes...
Seite 150 - ... that it contains. The solution of the question, whether marl, mild lime, or powdered limestone, ought to be applied, depends upon the quantity of calcareous matter already in the soil. All soils are improved by mild lime, and ultimately by quick-lime, which do not effervesce with acids ; and sands more than clays.
Seite 92 - It may cool the dung for a short time ; but moisture, as before stated, is a principal agent in all processes of decomposition. Dry fibrous matter will never ferment. Water is as necessary as air to the process ; and to supply it to fermenting dung, is to supply an agent which will hasten its decay. In all cases when dung is fermenting, there are simple tests by which the rapidity of the process, and consequently the injury done, may be discovered. If a thermometer, plunged into the dung, does not...
Seite 89 - During the violent fermentation which is necessary for reducing farm-yard manure to the state in which it is called short muck, not only a large quantity of fluid, but likewise of gaseous matter, is lost; so much so, that the dung is reduced one half, or two...

Seite 91 - ... his manure goes nearly twice as far. A great objection against slightly fermented dung is, that weeds spring up more luxuriantly where it is applied. If there are seeds carried out in the dung they certainly will germinate; but it is seldom that this can be the case to any extent; and if the land is not cleansed of weeds, any kind of manure fermented or unfermented will occasion their rapid growth. If slightly fermented- farm-yard dung is used as a...

Seite 168 - Lecture, that the earthy and alkaline substances seem never to be formed in vegetation ; and there is every reason likewise to believe, that they are never decomposed ; for after being absorbed they are found in their ashes. The metallic bases of them cannot exist in contact with aqueous fluids ; and these metallic bases, like other metals, have not as yet been resolved into any other forms of matter by artificial processes; they combine readily with other elements ; but they remain undestructible,...
Seite 7 - And I do flux the whole, by adding six parts, by weight, of limestone for every five of such parts of the raw mine rubbish as may have been used for the purpose last before mentioned.
