Pagina 11 - ... constituents, being implied by fermentation. The most reasonable explanation of the fermentation of sugar has been given by Liebig. Ferments, the great German chemist says, being in a state of decomposition, have their constituent particles in a state of motion, and by communicating, mechanically, on impulse or motion to the particles of sugar, destroy the balance of affinities, to which its existence is owing, and thus give rise to a new balance or equilibrium more stable under existing circumstances....
Pagina 12 - ... field, hay, nevertheless, heats to some extent in the stack. A slight fermentation so far from being injurious, may be useful, for as is well known, peculiar aromatic principles are thus generated, which certainly renders hay more palatable, and it may be, more nutritious. As long as the green color is retained there is no danger of the hay losing in quality, but if the heat in the stack becomes so intense and continuous as to turn the hay decidedly brown, I have no hesitation in saying that...
Pagina 165 - ... crops is stimulated. In nearly all the cases reported it will be seen that the expenses of cultivation are very much reduced, and yet that a larger amount of produce is said to have been realised. The reduction of expenditure is more susceptible of proof than increase of produce.
Pagina 6 - IF grass or clover could be made into hay without undergoing any change in composition, the hay, when made, would no doubt be found as valuable as the green food from which it was derived. From exposure to the broiling heat of the sun on a hot summer's day, cut grass or clover hardly lose anything else but water, neither do their constituents undergo material alterations if the grass is not much bruised, and the drying process takes place with sufficient rapidity. The green colour, sweet taste, and...
Pagina 8 - ... liable to be washed out, but the bruised state of the plants, admitting at least a partial diffusion of the various constituents through the lacerated cell-walls, induces fermentation, which, if not checked at once, causes further loss. During the fermentation soluble albumen and sugar are destroyed — two of the most valuable elements of nutrition. In showery weather, grass recently cut should, for this reason, not be turned over more than is absolutely necessary, and under all circumstances...
Pagina 87 - The seven-horse-power engine did three acres a day to the same depth. mixed with subsoil, and produces a straw stout and standing erect. The root crops are also better. Work is done not only with greater despatch, but with greater certainty. It was once difficult to say when four teams would finish a 20-acre field, but with steam the time of finishing cnn be predicted to within an hour.
Pagina 465 - They state further that to obtain a maximum amount and gross value of produce from a given amount of sewage, it should be applied in small quantities per acre, and in dry weather; but the great dilution of town sewage, its large daily supply at all seasons, and its greater amount in wet weather, when the land can least bear, or least requires, more water, render it quite inappropriate for application on a comprehensive scale to arable land for corn and other ordinary rotation crops.
Pagina 535 - ... series of experiments to between 3 and 4 tons per acre ; and the further profit on the increase of the size of the set from 4 ozs. to 8 ozs., averaged about 5 tons an acre ; all the intermediate steps partaking proportionately of the increase. Secondly. The advantages in favour of the large sets is more marked in the late than in the early varieties. Thirdly. In the use of small sets of from 1 oz. to 3 ozs. in weight, a larger balance over and above the weight of the sets was obtained by planting...
