Страница 59 - And it shall come to pass in the increase, that ye shall give the fifth part unto Pharaoh, and four parts shall be your own, for seed of the field, and for your food, and for them of your households, and for food for your little ones.
Страница 248 - ... but whoever will refer to the simplest principles of chemistry, cannot entertain a doubt on the subject. As soon as dung begins to decompose, it throws off its volatile parts, which are the most valuable and most efficient. Dung which has fermented, so as to become a mere soft cohesive mass, has generally lost from one third to one half of its most useful constituent elements.
Страница 249 - Dry straw of wheat, oats, barley, beans, and peas, and spoiled hay, or any other similar kind of dry vegetable matter, is, in all cases, useful manure. In general, such substances are made to ferment before they are employed, though it may be doubted whether the practice should be indiscriminately adopted.
Страница 226 - Mucilaginous, gelatinous, saccharine, oily, and extractive fluids, and solution of carbonic acid in water, are substances that in their unchanged states contain almost all the principles necessary for the life of plants; but there are few cases in which they can be applied as manures in their pure forms ; and vegetable manures, in general, contain a great excess of fibrous and insoluble matter, which must undergo chemical changes before they can "become the food of plants.
Страница 379 - Winchester bushels of lime. First, a layer of dry sods or parings, on which a quantity of lime is spread, mixing sods with it, then a covering of eight inches of sods, on which the other half of the lime is spread, and covered a foot thick ; the height of the mound being about a yard.
Страница 288 - It combines likewise with the animal acids ; and probably assists their decomposition by abstracting carbonaceous matter from them combined with oxygen ; and consequently it must render them less nutritive. It tends to diminish likewise the nutritive powers of albumen from the same causes ; and always destroys to a certain extent the efficacy of animal manures, either by combining with certain of their elements, or by giving to them new arrangements. Lime should never...
Страница 408 - ... with earth, dung, or other manures, and let them lie to ferment — that if used alone, they may either be drilled with the seed or sown broadcast— that bones which have undergone the process of fermentation are decidedly superior...
Страница 486 - ... kept on the same field ; for the foul grass produced by the dung of some animals, will be consumed by others ; and as it is well known that different species of cattle prefer different kinds of grass, there is an evident advantage in this practice. In every field, numerous plants spontaneously spring up, some of which are disliked by one class of animals, while they are eaten by others ; and some of which plants, though eaten with avidity at a particular period of their growth, are entirely rejected...
Страница 435 - ... action of ammonia. In like manner, stale liquid manure is not so good a top-dressing to grass as fresh, or when it is largely mixed with water ; because science now informs us, that ammonia becomes concentrated in stale liquid manure, and is therefore in an injurious state for plants ; and that it is necessary to mix liquid manures largely with water, in order to dilute the ammonia, and allow the proper action of the humic acid, which exists in large quantity in them.
Страница 493 - Next, the grass-cocks are to be well shaken out into staddles (or separate plats) of five or six yards diameter* If the crop should be so thin and light as to leave the spaces between these staddles rather large, such spaces must be immediately raked clean, and the rakings mixed with the other hay, in order to its all drying of a uniform colour.
