Chapter 6

_For wheat_, the guano should be spread broadcast at the time of seeding the wheat, at the rate of 200 lbs. to 250 lbs. per acre and ploughed in. If the land has been previously fallowed, it will be sufficient to plow it in with a one horse plow; if broken up for the first time, there will be no objection to using a larger plough. The best depth for getting it in, however, is, I think, from four to six inches. It always acts more powerfully on clean land; indeed if there is much crude vegetable matter in the soil, there is frequently little or no advantage derived from its application. Experience, therefore goes to show that the most economical application is to corn land; that is, to land that has just produced a crop of corn, no matter how poor it may be. If it is intended to be put on land that has been lying in grass, it would be advisable to fallow it as early in the season as practicable, and afterwards to get it in with a small plow as already suggested.

The same direction will apply to oats and also to rye. But for oats, 125 to 150 lbs of guano will be as much as can be used to advantage.

A. B. Allen of New York, one of the earliest, and most strenuous advocates of using guano, who, long before he ever thought of being engaged in its sale, used to distribute small parcels among farmers and gardeners to enable them to try experiments and learn its value, in a letter to the Southern Cultivator, says:--"Never put guano in the hill with corn, no matter if covered two or three inches deep; for the roots will be certain to find it, and so sure as they touch the guano, so caustic is it, that it will certainly kill the corn; the same with peas, beans, melon vines, in fact most vegetable crops. Wheat and other small grains have so many roots, and tiller so well, there is no danger of guano killing them, when sown directly with the seed. Still, as before remarked, it is better to plough it in before sowing the seed.

"After corn is up, you may apply a table spoonful, at the first time hoeing; dig it an inch or two deep six inches from each stalk. A table spoonful to the hill will take 250 to 350 lbs., per acre, according to the distance the hills are apart. If the soil be rather poor, a second dose at the time the corn first shows its silk, will add considerably to the yield in grain, if followed by rains, but little or nothing to the growth of stalk. Guano increases the size of grain more than stalks; hence one must be content to wait till the grain is fully matured before giving an opinion of the virtues of guano.

"Before applying the guano, it is better to mix it well with an equal quantity of plaster of Paris or charcoal dust. Either of these substances help to retain the ammonia and prevent its evaporation.

"The genuine unadulterated Peruvian guano, is so much superior to any other kind, it is in reality the _cheapest_, though the price is considerable higher than that of the other qualities."

_Guano on Oats._--Mr. Allen says, "I am satisfied from experience and observation in the use of guano, for the past twelve years, that the best method, decidedly, of applying it to crops in our dry climate, is to plow or spade it into the ground; and autumn is the best time for doing this, as it gives time for the pungent salts contained in the guano, to get thoroughly mixed with the soil before spring planting. Do not fear to loose the guano by plowing it in as deep as you please--it will not run away, depend upon it. At the south, it loses half its virtue if not plowed in at least three inches deep; six or twelve inches would be still better."

Because "autumn is, for many reasons, the best season" for applying guano, as a general thing, we do not recommend an application to this crop, notwithstanding our full conviction it will increase the product upon any light, poor soil, from ten to twenty bushels to the acre, for each cwt. applied. As some however, will find it more convenient and profitable to manure the oat than wheat crop, we recommend them to plow in from 200 to 300 lbs. to the acre, on ground that was clean tilled the previous year, and sow the oats in drills, three or four bushels to the acre and seed with clover, herds, or ray grass. If not to be followed with grass, we would use a much less quantity; say 125 or 150 lbs. to the acre. As may be seen in the account of Mr. Harris' crop, not one half of the 400 lbs. was taken up by the oats. With wheat, on the contrary, the guano is dissolved more slowly by winter rains, giving the crop a vigorous growth in fall, and sometimes all winter, so it sends out double the number of stalks in spring. The sun too, is so much less powerful at that season, evaporation does not take place so easily as in summer.

_Great Crops from Guano._--In England, 48 bushels of wheat and 100 of oats have been made from an acre dressed with 200 lbs. of guano. A late English writer, in detailing his own experiments, and urging others to the same course, says; "The reason guano is serviceable to all plants arises from its containing every saline and organic matter required as food. It is used beneficially on all soils; for, as it contains every element necessary to plants, it is independent of the quality of the soil. So far as the experiments in England and Scotland may be adduced, one cwt. of guano is equal to about five tons of farm-yard manure, on an average; but it is much higher for turnips than for grass."

_Guano on Grass._--As we are opposed to using it as a top dressing, of course we shall not recommend its application to this crop. Generally, by using it on wheat and other crops, the farmer will save manure enough to top dress his meadows. Nevertheless, in combination with proper ingredients, we do say it is a good and profitable manure for grass. For each acre mix from 200 to 400 lbs. with as many bushels of plaster, or ten to one of charcoal, or twenty to one of dry swamp muck or peat, woods mould or fine clay, and sow upon the meadow or pasture early in spring. If the season is moist, the benefit will be very great; if dry, it will probably be said, as it has been before; "Oh, this guano is good for nothing--I tried it once on grass and it never done a bit of good."

_On potatoes_, 400 lbs. to the acre, broadcast, may be used to good advantage, if it is plowed in deep enough, on clean land. As it is a caustic manure, and requires a good deal of moisture, as well as potatoes, it is not suitable for the hill or surface dressing. A less quantity will pay a greater profit to the immediate crop, without much after benefit, if it is drilled in the bottom of a deep furrow and then covered by turning two furrows, one from each side, so as to leave a slight depression between them, and directly over the guano. Upon these beds plant the tubers in drills. After hoeing, scatter a mixture of equal parts of lime, salt, ashes and plaster, a large handful every yard, all over the rows, and we will warrant the crop free from the potato rot.

_On turnips_, nothing can exceed guano, unless the phosphate of lime in bones could be rendered equally pulverulent. Use 3 to 600 lbs. per acre, and plow it in at the last plowing, and top dress with five bushels of ashes and two of salt as soon as the turnips are up. Follow with wheat or rye and grass. One half the above quantity and five bushels of bone dust dissolved in sulphuric acid, will produce a wonderful crop of turnips, or ruta bagas. Guano may be used to equal advantage upon all kinds of root crops.

_Benefits to the Dairy Farmer._--The beneficial use of guano in the manufacture of butter and cheese, is unquestionable. In many districts in England, and in some in this country, the continual cropping of grass and conversion of it into cheese, has so exhausted the soil of its phosphates, the milk will no longer produce the quantity of casein necessary to make cheese making profitable. When this is the case, you will find the cows seeking to supply the deficiency by eating bones. Wherever guano has been used upon pasture land, it is found that cows eat the increased luxuriant grass most greedily, and improve not only in quantity but quality of their milk. We cannot, therefore, recommend too earnestly, to all dairy farmers, to give their pasture lands an immediate dressing of guano. If you have not full faith in what we are telling you, try an experiment for yourself. Mix 200 or 300 lbs. of guano with two or three bushels of plaster, and that with two or three loads of charcoal dust from the bottom of some coal pit, or from burnt peat, or swamp muck; or, if the charcoal is not attainable, use woods mold, or powdered clay or fine loam, to any extent you can afford; and if you can afford nothing but the guano and plaster, don't fail to afford a dressing of that, because it will afford you a rich return. No other manure can be used upon pasture land, to produce the same effect. Cattle never reject the grass of guanoed land, as they do that lately manured.

_On Flax._--Experiments in England have proved guano superior to any other substance ever applied to this crop. With the aid of this manure, farmers will never complain of flax exhausting the soil. With 300 lbs. per acre, successive large crops can be grown upon the same ground. It should be plowed in, but not so deeply as for some other crops, as it is not expected to benefit succeeding ones as much as the present. As soon as the "flax cotton" movement now progressing is fully understood, there will be immense fields of flax grown for that purpose, and the best and most economical fertilizing material, and for which there will be a large demand, will be Peruvian guano; for no good farmer will attempt to grow a crop without it. A top dressing of 25 or 30 bushels of ashes to the acre will be found beneficial; but farmers ought to try which is best, more guano and less or no ashes, or the reverse. We cannot advise rotation with this crop, where guano is used, because the ground becomes so clean and free from weeds, it is of great advantage, and so far as we are informed, continuous good crops result from the annual application of the same quantity of guano, year after year.

_On Cabbages._--Field culture. After the ground is well prepared, lay it off in checks three to four feet square. With a spade, throw out a deep spit at each check and put in a spoonful of guano, or at the rate of 400 lbs. per acre, and cover with soil. Set the plants immediately and water if possible. After the first hoeing, throw a handful of ashes on each plant.

_For Carrots, Beets and Parsnips_, plow in 500 lbs. per acre, twelve to eighteen inches deep. Top dress with ashes, salt, and fine manure in compost, to assist the young plants; the long roots will find the guano and it will produce such a crop as you never saw before.

_On Hops._--Make a mixture of three cwt. of guano, one of salt, one and a half of saltpetre, and one of gypsum, for each acre; sow broadcast and plow in about four inches deep, and you will find your manure well paid for, and no exhaustion of the soil, as is usually the case wherever this crop is cultivated, as it is a very gross feeder, and requires very rich land or great deal of manure; for which reason it is not as much cultivated as it will be as soon as the virtues of the above application become fully known.

_For Tobacco_, guano has been found to possess superior qualities, particularly in obviating the difficulty heretofore experienced in getting plants sufficiently early. We have the testimony of several witnesses to prove that burning a seed bed is quite unnecessary, if guano at the rate of 400 to 600 lbs. to the acre be mixed with an equal amount of ashes, and plaster and well raked in previous to sowing. Of the effect upon the crop, we give the testimony of a Virginia planter.

"In the spring of 1850, I applied 200 lbs. to the acre, on eight acres of land, which had been manured three years before for tobacco, and the same quantity, on three acres which had never been manured, and was very poor. On the last I also turned in some half rotted straw, raked up in the barn yard, after all the farm yard manure had been hauled out. Between these two pieces of land, 19 acres were heavily manured. The whole 30 acres had been well broken with four horses, early in the winter. The last year was the worst I have ever known for tobacco. Nevertheless, the first eight acres produced a very fine crop--the last three acres brought much better tobacco than the adjoining manured land, I should say not less than 600 lbs. to the acre."

_Wheat on Guanoed Tobacco Land._--This field was sown with wheat, and the writer says--"I measured from these 30 acres next year upwards of 600 bushels of wheat of very fine quality; both pieces of guanoed land being _above_ the average of the whole lot. Adjoining the _three_ acres is an equal quantity of land of the same quality, which did not yield five bushels to the acre."

Of the effect upon another crop of wheat, the same gentleman says--"Two years ago I purchased three tons, two of which I applied to 20 acres of a James River hill, which though not gullied, had been a good deal worn by hard croppings, or bad cultivation, or both combined. The Guano was sowed _dry_, and on the wide rows laid off for sowing wheat, and ploughed in with two horses, the wheat then harrowed in. I forgot to say that the land had been fallowed in with three horses in the month of August, and the wheat sowed in October. In consequence of the dryness of the guano, and the width of the rows, the wheat was very much striped, being very luxuriant where the guano fell in the largest quantities. The product did not exceed 200 bushels, or 10 bushels to the acre, but the quality was so superior that I saved it all for seed."

"The land sowed two years ago, is now _striped with clover_, as it was with wheat."

This land is a tenacious red clay formation, from which the soil we presume has all been washed away "long time ago." No planter, he says, would have put such land in tobacco without heavy manuring; and yet it produced a fair crop of tobacco. Owing to distance from navigation, he could not use lime, or any heavy manure, and without guano he could not make crops, and, consequently could not make manure at home.

The editor of the American Farmer, in a note says--"Our correspondent appears to desire that his land should be brought to a state of fertility by the _quickest_ practicable process, and from the beautiful results of his experiments with guano, we know of no agent to which he could look with so much certainty of success as to that very manure."

_The quantity per acre for Tobacco._--We should recommend at least 400 lbs. sown broadcast and plowed in, on such land as described, not over four inches deep. The tobacco to be followed with wheat, the wheat with clover, the clover after one year with corn and then tobacco and guano again. The clover should have a bushel of plaster fall and spring. Whoever tries this will find the benefit of guano on tobacco. But there is one still greater benefit; we have been assured that the tobacco worm which it was supposed from his natural taste, nothing could nauseate, actually gets sick of guano, and refuses his accustomed food.

_Another mode of applying_ it to tobacco has been practised successfully as follows:--Mark off the land in checks and put a small spoonful in each check, and cover up directly under the bed where the plant is to stand, three or four inches deep. To this a handful of ashes and plaster may be advantageously added. Guano does not give tobacco the rank flavor that is often acquired from high manuring.

Mr. Pleasants, although many experiments have failed, principally, as he believes, from improper application, says in a recent letter--"There is no actual reason why guano should not act as well on tobacco as any other crop. The failures are doubtless to be ascribed to the injudicious manner in which it has been applied. I can conceive of only one mode in which it can be used to advantage, and that is by strewing it along a deep furrow as described for corn; then bedding upon it and confining the cultivation to one direction. This has been my way of cultivating cabbages for the market for several years, and the guano has always acted promptly and powerfully. If chopped in at the base of the hill it would require a great quantity of rain to dissolve it and make it available to the young plants, for the conical shape of the hill has a tendency to shed the rain instead of absorbing it. I expect soon to receive very accurate results of a crop grown with guano, which Judge Nash represented to me as splendid. If I cultivated tobacco, I should have every confidence of success by planting it on ridges with the Guano buried at a considerable depth, say from four to six inches beneath the surface of the ridge--1 lb. to ten yards would be a sufficient quantity.

"In short, I consider guano good for any crop. For potatoes (that is Irish potatoes) I regard it as a specific manure. The quantity I apply is 3/4 lbs. to every ten yards put in the furrows as recommended for corn and tobacco, and then covered over about one inch with earth drawn from the sides of the furrows. After this the potato cuttings are planted and covered over with the plough or hoe. The quantity recommended is about right as far as my experience goes (which is of several years duration) if the cuttings are placed about two inches apart."

_Guano for Cotton._--But few trials upon this crop have come to our knowledge, but such as have, indicate that it will prove one of the most valuable promoters of the growth of this staple product of America ever discovered. The analysis of cotton--stalk, seed and lint--compared with that of guano, is sufficient to prove the latter to be the very matter required to produce the former. We are assured upon the most reliable authority that guano will give an average increase of pound for pound upon any soil producing less than a bale per acre so that every pound of guano costing two and a half cents, will give a pound of cotton averaging at least 6-1/4 cents.

_Mode of applying on Cotton Land._--Open a deep furrow and drill in the bottom at the rate of 400 lbs. to the acre, upon land usually producing 300 to 500 lbs. seed cotton, and less for a better quality of land, down to one-fourth the quantity. Bed on this as deep as you please; the moisture of the earth will disengage the ammonia and phosphates, and send their fertilizing properties up to the roots. Never use guano as a top-dressing for cotton. The seed will be found better matured, and consequently more valuable to manure another crop, besides being so much easier separated from the lint, which will be found as much improved in quality as quantity. For Sea Island planters, where manure is so valuable and so hard to obtain, we would earnestly recommend a thorough trial of guano. As the land for this crop is mostly prepared with hoes, care must be taken that the servants do not neglect to bury it at the very bottom of a good bed.

From the knowledge the writer has of the culture and value of long staple cotton, and the price and value of guano, he has no hesitation in expressing his honest conviction that a clear profit of two to four hundred per cent. may be made upon every dollar expended in the purchase and proper application of guano to that crop.

Guano, for all staple crops in the United States, is no longer an experiment. It has been clearly demonstrated, to be the cheapest and most valuable fertilizer, particularly for all poor, worn out, hard used and exhausted soils ever discovered; which no sensible man will neglect to profit by, as soon as he learns its value, unless prevented by deep prejudice or strong circumstances.

_Application to Miscellaneous Crops._--Under this head we will give the experience of several individuals in various sections, soils and climates, in hopes it may encourage the doubtful, and direct those who are disposed to emerge from darkness into the light of scientific agriculture. A gentleman from Warsaw, Virginia, where the soil is generally a sandy loam, badly worn by long years of bad tillage, says, "My wheat looks finely, especially where I applied guano last fall. I put it in with the seed furrow about three inches deep, and also with double plow six inches deep, harrowing in the wheat frequently side by side. At this time I can see no difference in the wheat crop. I use a large wooden toothed harrow extending over the bed of ten feet, and an even soil, free from stone; they do admirable work and drill the wheat as if put in with the drill."

Willoughby Newton, whose operation we have already spoken of, says; "I do not believe it possible to improve a farm, on the old three shift system, of corn, wheat and pasture, without a large supply of foreign manures. If clover can be substituted for pasture in the summer, then the land, if not naturally poor, may be rapidly improved by the use of lime alone, in addition to the putrescent manures that may, by proper care, be made on the farm. On other land of less fertility, and drier, I greatly prefer the five field system, under which, with the use of lime, guano and clover, a rapid improvement may be effected at the same time that heavy crops of wheat are reaped."

Another writer in speaking of how to improve worn out lands, says; "Let whatever little surplus he can spare from supplying the necessary wants of his family be laid out in the purchase of some one of the reliable concentrated manures. [Guano is by far the cheapest, and therefore the best for him, if he will plow it in well]. And my observation and experience have convinced me that he may make such improvement as will bring him a quick return, and soon enable him to get his farm well set in grass. This once effected, his facilities for its further improvement will assuredly increase in a ratio just in proportion as he is careful to pursue the course indicated. If a farmer can succeed in getting his fields well set in grass, a large and long array of facts and experience have proved that he may then, under a judicious course of management, render them more and more fertile without foreign aid of any kind whatever."

The editor of the American Farmer, in deprecating the price of guano says, "Of the efficacy of guano, in restoring worn out lands to productiveness--of its capacity to increase the yield of any lands in a sound condition--there cannot be a doubt; but even with all its regenerating properties, we do think that its market value is too high. Forty-eight dollars for a ton of 2,000 lbs. of Peruvian guano is more than it is intrinsically worth, and should it be continued thus high, must, we should think, limit its use, for the obvious reason, that farmers cannot afford to pay a price for it which is so disproportionate to its real value."

Yet they do continue to pay, and make it pay a greater profit than any other manure ever purchased. We hold to have done as much as any other individual to reduce the price of guano, and wish as heartily as does the editor of the Am. Farmer, it was only half the price it now is; yet, we must counsel our readers not to wait for that cheap time coming. It is now cheaper than it was then, and probably as low as it will be for years; and in the hands of the present agents, the public may depend upon a regular supply, and of genuine quality, at what the Peruvian government deem a fair price.
