SECTION 3 (MANURES) CHAPTER VI (DIFFERENT KINDS OF ANIMAL EXCREMENT) Pg 116

 

Night soil has been used as a manure, for ages, in China, which is, undoubtedly, one great secret of their success in supporting a dense population, for so long a time, without impoverishing the soil. It has been found, in many instances, to increase the productive power of the natural soil three-fold. That is, if a soil would produce ten bushels of wheat per acre, without manure, it would produce thirty bushels if manured with night soil.

Some have supposed that manuring with night soil would give disagreeable properties to plants: such is not the case; their quality is invariably improved. The color and odor of the rose become richer and more delicate by the use of the most offensive night soil as manure.

[What is the direct object of plants?

What would result if this were not the case?

How may night soil be easily prepared for use, and its offensive odor prevented?]

It is evident that this is the case from the fact that plants have it for their direct object to make over and put together the refuse organic matter, and the gases and the minerals found in nature, for the use of animals. If there were no natural means of rendering the excrement of animals available to plants, the earth must soon be shorn of its fertility, as the elements of growth when once consumed would be essentially destroyed, and no soil could survive the exhaustion. There is no reason why the manure of man should be rejected by vegetation more than that of any other animal; and indeed it is not, for ample experience has proved that for most soils there is no better manure in existence.

A single experiment will suffice to show that night soil may be so kept that there shall be no loss of its valuable gases, and consequently no offensive odor arising from it, while it may be removed and applied to crops without unpleasantness. All that is necessary to effect this wonderful change in night soil, and to turn it from its disagreeable character to one entirely inoffensive, is to mix with it a little charcoal dust, prepared muck, or any other good absorbent--thus making what is called poudrette. The mode of doing this must depend on circumstances. In many cases, it would be expedient to keep a barrel of the absorbent in the privy and throw down a small quantity every day. The effect on the odor of the house would amply repay the trouble.

[Should pure night soil be used as a manure?

What precaution is necessary in preparing hog manure for use?]

The manure thus made is of the most valuable character, and may be used under any circumstances with a certainty of obtaining a good crop. It should not be used unmixed with some absorbent, as it is of such strength as to kill plants.

For an analysis of human manure, see Section V.

HOG MANURE.

Hog Manure is very valuable, but it must be used with care. It is so violent in its action that, when applied in a pure form to crops, it often produces injurious results.

SECTION 3 (MANURES) CHAPTER VI (DIFFERENT KINDS OF ANIMAL EXCREMENT) Pg 118

 

It is liable to make cabbages clump-footed, and to induce a disease in turnips called ambury (or fingers and toes). The only precaution necessary is to supply the stye with prepared muck, charcoal-dust, leaf-mould, or any absorbent in plentiful quantities, often adding fresh supplies. The hogs will work this over with the manure; and, when required for use, it will be found an excellent fertilizer. The absorbent will have overcome its injurious tendency, and it may be safely applied to any crop. From the variety and rich character of the food of this animal, his manure is of a superior quality.

[Why is the manure from butchers' hog-pens very valuable?

How does the value of poultry manure compare with that of guano?

How may it be protected against loss?]

Butchers' hog-pen manure is one of the best fertilizers known. It is made by animals that live almost entirely on blood and other animal refuse, and is very rich in nitrogen and the phosphates. It should be mixed with prepared muck, or its substitute, to prevent the loss of its ammonia, and as a protection against its injurious effect on plants.

POULTRY HOUSE MANURE.

Next in value to night soil, among domestic manures, are the excrements of poultry, pigeons, etc. Birds live on the nice bits of creation, seeds, insects, etc., and they discharge their solid and liquid excrements together.

SECTION 3 (MANURES) CHAPTER VI (DIFFERENT KINDS OF ANIMAL EXCREMENT) Pg 119

 

Poultry-dung is nearly equal in value to guano (except that it contains more water), and it deserves to be carefully preserved and judiciously used. It is as well worth twenty-five cents per bushel as guano is worth fifty dollars a ton (at which price it is now sold).

Poultry-manure is liable to as much injury from evaporation and leaching as is any other manure, and equal care should be taken (by the same means) to prevent such loss. Good shelter over the roosts, and daily sprinkling with prepared muck or charcoal-dust will be amply repaid by the increased value of the manure, and its better action and greater durability in the soil. The value of this manure should be taken into consideration in calculating the profit of keeping poultry (as indeed with all other stock). It has been observed by a gentleman of much experience, in poultry raising, that the yearly manure of a hundred fowls applied to previously unmanured land would produce extra corn enough to keep them for a year. This is probably a large estimate, but it serves to show that this fertilizer is very valuable, and also that poultry may be kept with great profit, if their excrements are properly secured.

The manure of pigeons has been a favorite fertilizer in some countries for more than 2000 years.

Market gardeners attach much value to rabbit-manure.

SHEEP MANURE.

[What can you say of the manure of sheep?]

The manure of sheep is less valuable than it would be, if so large a quantity of the nitrogen and mineral parts of the food were not employed in the formation of wool.

SECTION 3 (MANURES) CHAPTER VI (DIFFERENT KINDS OF ANIMAL EXCREMENT) Pg 120

 

This has a great effect on the richness of the excrements, but they are still a very good fertilizer, and should be protected from loss in the same way as stable manure.

GUANO.

[Should the use of guano induce us to disregard other manures?

Where and in what manner is the best guano deposited?]

Guano as a manure has become world renowned. The worn-out tobacco lands of Virginia, and other fields in many parts of the country, which seemed to have yielded to the effect of an ignorant course of cultivation, and to have sunk to their final repose, have in many cases been revived to the production of excellent crops, and have had their value multiplied many fold by the use of guano. Although an excellent manure, it should not cause us to lose sight of those valuable materials which exist on almost every farm. Every ton of guano imported into the United States is an addition to our national wealth, but every ton of stable-manure, or poultry-dung, or night soil evaporated or carried away in rivers, is equally a deduction from our riches. If the imported manure is to really benefit us, we must not allow it to occasion the neglect and consequent loss of our domestic fertilizers.

The Peruvian guano (which is considered the best) is brought from islands near the coast of Peru.

The birds which frequent these islands live almost entirely on fish, and drop their excrements here in a climate where rain is almost unknown, and where, from the
