Guano: A Treatise of Practical Information for Farmers
24]"/> in the same manner as the other. During the succeeding winter and spring, the appearance of my wheat field became the subject of much notice and remark on the part of my neighbors, as well as others from several adjoining counties who saw it, many of whom supposed that this application of guano could not possibly produce such a crop as its then present appearance indicated—in this, however, they were disappointed—there were two small pieces left without manure of any kind. One of these upon the best part of the field, and the other upon a part of medium quality.
"It may be recollected that the crop of wheat that season was generally most inferior, both in quality and quantity. Upon the parts left without manure, it was scarcely worth cutting, and men of integrity and good judgment, were of the opinion that without the aid of the guano, I could not have saved more than 60 or 70 bushels of wheat from the field. The product was 320 bushels, that weighed 64 lbs. to the bushel. The guanoed portion continued at harvest to be decidedly better than that manured from the barn yard and stable. This field was sown with clover in the spring of 1846, and to this time its appearance affords as strong evidence of great improvement in the land, as it did during the growth of wheat. It has now been pastured freely during two summers, and been exposed to the action of the frosts of two winters, and upon the guanoed portion I have not yet seen a single clover root thrown out of the ground, while from the part manured from the barn yard, it has almost entirely disappeared. Good farmers have frequently remarked during the present summer that the appearance of this field warrants the conclusion that it is now capable of producing largely of any crop common to our country.
"Thus 'worn out land' is renovated, and ample means produced for increasing its fertility. Similar instances of improvement exist in very many examples that can be seen in this portion of our country, resulting from the application of lime, bone and poudrette, as well as from guano."
Guano prevents clover from being thrown out by frost.—We wish to call back the attention of the reader to this reliable statement of Mr. Stabler, not only for its importance to farmers, but because the same thing has been remarked by other gentlemen who have used guano. It can only be accounted for from the fact, that guano seems to be peculiarly adapted, more than any other manure, to give the young clover a vigorous start, so that in its early stages it acquires a growth too strong to be affected by the usual course of freezing and thawing, by which less vigorous plants are thrown out. For this reason alone, if guano had no other value, farmers in some sections of the country where the soil is peculiarly affected by this difficulty, would find their account in the use of an article which would enable them to grow clover, for clover is manure, and it should be a sine qua non with every farmer to avail himself of all the means within his reach to increase the supply of manure from the products of his farm. Let him not depend alone upon the purchase of guano, but rather upon the means which that brings within his reach of increasing his home supply by the growth of clover, and largely increased production of straw. Those who are interested pecuniarily, which the writer is not, in the increased sale of guano in the United States, have no fears that our recommendations to make manure at home—to use lime, plaster, bones, clover, and every other source of fertility within their reach, will decrease the sale of guano. On the contrary, those who are most disposed to use all these sources of fertility, are the very men most disposed to use a substance which all experience has proved superior to all others. Besides, there is, and probably always will be, enough "worn out lands" which can be profitably renovated, to use up all the guano which will ever find its way into this country. So our earnest recommendation is, where lime is available, let no man claiming the honorable title of farmer, fail to make the application. Let him also gather up all the fragments—let nothing be lost—make all the manure at home he possibly can, and then he will not only have the means, but a disposition also to buy that which a beneficent Providence sends him from the coast of Peru; of the good effect of which we will prove by further testimony—that of the Hon. James A. Pearce, Senator from Maryland, and a farmer of no small note in that State. He says—"In April 1845, I applied 350 lbs., probably of African or Patagonian guano to an acre of growing wheat, the land being entirely unimproved and very poor. It was applied as a top dressing, of course, but mixed with plaster." (In what proportion he does not say, but we will by and bye; but he does say)—"The wheat was doubled in quantity at least—fine clover succeeded it—and in two crops, one of corn and one of small grain, three and four years afterwards, the effects are still apparent." Now this effect was produced by the use of the guano as a top dressing; a method universally acknowledged to be the most unfavorable to the development of the full value of the application.
The editor of the Farmer in answer to an inquiry whether a combination of charcoal, plaster, and guano would make a profitable top dressing in spring for wheat, says, "yes"—but thinks if it had been plowed in with the seed in the fall, the result would have been much better. However, says he, "we entertain not the slightest doubt, that, if his wheat field be top dressed with the mixture next spring, it will greatly increase the yield of his wheat crop, unless the season should prove a very dry one, as the charcoal, and plaster, will each tend to prevent the escape of the ammoniacal gases of the guano, and as it were, offer them up as food to the wheat plants.
"In April 1845, I applied 350 lbs. of guano to an acre of growing wheat, the land being entirely unimproved and very poor. Of course it was applied as a top-dressing, mixed, however, with plaster. The wheat was doubled in quantity at least; fine clover succeeded it; and in two crops, one of corn, and the other of small grain, last year and the present, the effects are still apparent."
If our correspondent would mix, in the proportion of 200 lbs. of guano, one bushel of charcoal, and half a bushel of plaster per acre, and sow the mixture on his wheat field next spring, after the frost is entirely out of the ground, then seed each acre with clover seed, and roll his land, we have no doubt that his wheat crop would be increased five or six bushels to the acre, perhaps more, and that he would have a good stand of clover plants, and a luxuriant crop of the latter next year.
"Our opinion is, that guanoed land should always be sowed to clover, or clover and orchard grass."
In this, particularly the opinion of the last paragraph, we fully concur—to obtain the full value of guano it must either be mixed with plaster or charcoal, or what is better, plowed in and thoroughly incorporated with the soil, and the land always sown with clover, peas or some other plant of equal value for green manure. It is true Col. Carter has been successful with wheat after wheat; while many continue successful, by carefully retaining all the straw; the guano being sufficient to keep up the everlasting ability of the soil to produce an annual crop of grain.
