Note 24 — CHAP. V. Of Tillage.

’Tis of late fully prov’d, by the Experience of many Farmers, that two or three additional Plowings will supply the Place of Dung, even in the old Husbandry, if they be perform’d at proper Seasons: and the hiring Price of three Plowings, after Land has been thrice plow’d before, is but Twelve Shillings, whereas a Dunging will cost three Pounds: This was accidentally discovered in my Neighbourhood, by the Practice of a poor Farmer, who, when he had prepared his Land for Barley, and could not procure Seed to sow it, plow’d it on till Wheat Seed-Time, and (by means of such additional Plowing) without Dung, had so good a Crop of Wheat, that it was judg’d to be more than the Inheritance of the Land it grew on.

The same Effect follows when they prepare Land for Turneps, since they are come in Fashion, and sow them several Times upon several Plowings, the Fly as often taking them off; they have from such extraordinary Tillage a good Crop of Wheat, instead of the lost Turneps, without the Help of Dung; hence double-plowing is now become frequent in this Country.

The Reason why Land is enrich’d by lying long unplow’d, is that so very few Vegetables are carried off it, very little being produc’d; the Exhaustion is less than what is added by the Atmosphere, Cattle, &c. But when ’tis plow’d, a vastly greater Quantity of Vegetables is produc’d, and carried off, more than by the old Husbandry is return’d to it.
