All Sorts of Land, when made fine by Tillage, or by Manure and Tillage, will serve to produce Turneps, but not equally; for chalky Land is generally too dry (a Turnep being a thirsty Plant); and they are so long in such dry poor Land before they get into rough Leaf, that the Fly is very apt to destroy them there; yet I have known them succeed on such Land, tho’ rarely. Sand and Gravel are the most proper Soil for Turneps, because that is most easily pulveriz’d, and its Warmth causeth the Turneps to grow faster, and so they get the sooner out of the Danger of the Fly; and such a Soil, when well-till’d, and Horse-ho’d, never wants a sufficient Moisture, even in the driest Weather; and the Turneps being drill’d will come up without Rain, and prosper very well with the sole Moisture of the Dews, which are admitted as deep as the Pulveration reacheth; and if that be to Five or six Inches, the hottest Sun cannot exhale the Dews thence in the Climate of _England_: I have known Turneps thrive well in a very dry Summer by repeated Horse-hoeings, both in Sand and in Land which is neither sandy nor gravelly. When I sow’d Turneps by Hand, and ho’d them with a Hand-hoe, the Expence was great, and the Operation not half perform’d, by the Deceitfulness of the Hoers, who left half the Land unho’d, and cover’d it with the Earth from the Part they did hoe, and then the Grass and Weeds grew the faster: Besides, in this Manner a great Quantity of Land could not be managed in the proper Season. When I drill’d upon the Level[69], at Three Feet Intervals, a Trial was made between those Turneps and a Field of the next Neighbour’s, sown at the same Time, whereof the Hand-hoeing cost Ten Shillings _per_ Acre, and had not quite half the Crop of the drill’d, both being measur’d by the Bushel, on Purpose to find the Difference[70]. [69] ’Tis impossible to hoe-plow them so well when planted upon the Level, as when they are planted upon Ridges; for if we plow deep near the Row, the Earth will come over on the Left-Side of the Plough, and bury the younger Turneps; but when they stand on Ridges, the Earth will almost all fall down on the Right Side into the Furrow in the Middle of the Interval. [70] And I have since found, that Turneps on the same Land, planted on Ridges, with Six-feet Intervals, make a Crop double to those that are planted on the Level, or even on Ridges with Three-feet Intervals.
