Note 118 — CHAP. IX. Of Wheat.
Reading edition
Tho’ the Ridge in the Middle of the Interval should, for Want of sufficient Mould, or otherwise, be too low to give Shelter, yet there is generally some Earth falls to the Left of the Hoe-plough, and lodges upon that Part which is left on the Outside of the Row; which, notwithstanding that Part be very narrow (as suppose Two or Three Inches), yet a small Quantity of Earth lying thereon, so near to the outside Row, gives an extraordinary Shelter to the young Wheat plants that grow in it.
Shelter is a great Benefit to Wheat; but yet Nourishment is more: for in the Winter I see the Wheat-plants upon the most exposed Part of the Ridge flourish, when single Plants in the Bottom of the Furrow are in a very poor languishing Condition, without any Annoyance of Water, they being upon a Chalk Bottom.
[119]Frost, if it does not kill the Wheat, is of great Benefit to it; Water or Moisture, when it is frozen in the Earth, takes up more Room than in its natural State; this Swelling of the Ice (which is Water congealed) must move and break the Earth wherewith it is mixt; and when it thaws, the Earth is left hollow and open, which is a kind of Hoeing to it. This Benefit is done chiefly to and near the Surface; consequently the more Surface there is, by the Unevenness of the Land, the more Advantage the Soil has from the Frost.
This is another very great Use of the Ridge left in the Middle of the Interval during the Winter; because that Ridge, and its Two Furrows, contain Four Times as much Surface as when level. This thus pulverized Surface, turned in in the Spring hoeing, enriches the Earth, in proportion to its Increase of internal Superficies, and likewise proportionably nourishes the Plants, whose Roots enter it; and that Part of it wherein they do not enter, must remain more enriched for the next Crop, than if the Soil had remained level all the Winter.
[120]It is a vulgar Error that the Winter Rains do not enrich the Earth; and is only thought so, because we do not see the Effect of them upon Vegetables, for lack of Heat in that Season. But some Farmers have frequently observed, that one half of a Ground plowed up just before Winter has produced a Crop of Barley as much better than the other Part plowed up at the End of Winter, as is the Difference of a Dunging, even when there has been very little Frost.
