Hitherto the want of enough cleared land has led farmers to put in wheat among the corn, and half put it in at that. Others have plowed their fallows, or their grass lands, so early in the season, that rains and settling have made it hard again by seed-time. Then, without stirring it, the grain has been thrown (away) upon it, and half harrowed in and left to its fate. Equally bad has been the system of late single plowing. Others have given their grain no soil to bed their roots in; a scratched surface receives the grain; its roots, like the steward, cannot dig, and so get no hold; and are either winter killed, or subsist upon the scanty food of the three or four inches of top soil. With some single exceptions, wheat cannot be said to have been cultivated yet. The two great operations in rendering soil productive of wheat, are either the development of the materials already in the soil; or, the addition to the soil of properties which are wanting.
Much land yielding only twelve or fifteen bushels, by a better preparation would, just as easily, yield thirty. Let us suppose that a common plowing of four or five inches, precedes sowing. Out of this superficial soil the wheat is to draw its food. Constant cropping has, perhaps, already diminished its abundance. Then wheat is rank in stem, short in the head, and light in the kernel. But below there is a bed of materials untouched. The subsoil, if brought up, exposed to the ameliorating influence of the elements, will furnish in great abundance the elements required. The simple operation of deep and thorough plowing will, often, be enough to increase the crop one-half. Deep plowing gives a place for the roots, which will not be
apt to heave out in winter; it saves the wheat from drought, it gives the nourishment of twice the quantity of soil to the crop.
Five acres may become ten by enlarging the soil downward. These remarks are desultory; and, while we intend to continue writing on the subject, we say to such as may be getting ready for the wheat-sowing, plow deeply and thoroughly; unlike corn, wheat can only be plowed once, and that at the beginning. It should be thoroughly done, then, once for all.
Wheat lands ought to be so farmed as to grow better from year to year; certainly, they ought to hold their own. Lands may be kept in heart by the adoption of a rotation suited to each particular soil; or, if frequent wheat crops are raised, by fallows or manuring. It is a fact that in this neighborhood farms in the hands of careful men are yielding better crops of wheat every year; while multitudes of farmers think themselves fortunate in twelve or fifteen bushels to the acre, there is another class who expect twenty-five or thirty bushels, and in good seasons get it. This is encouraging. As our lands get older we may look for yet better things. Some farmers put in from 100 to 800, and even 1,000 acres of wheat. The native qualities of the soil are relied upon for the crop. To manure or clover such a body of land is impossible with any capital at the command of its owners. But with us, each owner of a quarter section puts in from ten to twenty acres, and it lies within his means to dress this quantity of land to a high degree.
Soils fit for Wheat.—A vegetable mold cannot yield wheat, because it does not contain, and therefore cannot afford to the crop, silicate of potash, or phosphate of magnesia; the first of which gives strength to the stem, and the second of which is necessary to the grain. On such soil wheat may grow as a grass, but not as a grain.
A mere sand will not yield wheat; because wheat requires, and such soils do not contain, soda, magnesia, and especially silicate of potash.
All clays contain potash, which is indispensable to wheat, but they may be deficient in soda, in magnesia, and in other alkalies.
A calcareous clay-loam may be regarded as the best soil for wheat. And when it does not exist in a natural state, all the additions in the form of manure should be with reference to the formation of such a soil. If the land be light and sandy, clay, and marl, and wood ashes should be added, together with barnyard manure; if the soil is a tenacious clay, it should be warmed and mellowed by sand and manure; if it is deficient in lime, lime in substance, or in marl must be given; vegetable molds, if heavily dressed with wood-ashes and lime, may be brought to produce wheat.
To prepare the Ground.—This operation depends upon the condition of the soil. But, in all cases, the deepest plowing is the best. The roots of wheat, if unchecked, will extend more than five feet. Stiff, tough, soils, unbroken for years, and especially if much trampled by cattle, will require strong teams. Oxen are better than horses to break up with. It has been said, that a yoke of cattle draw a plow deeper, naturally, than a span of horses. They are certainly better fitted for dull, dead, heavy pulling. And if oxen have been well trained they will do as much plowing in a season as horses, and come out of the work in better condition.
