Another Thing I have more particularly observ’d, _viz._ That the more successive Crops are planted in wide Intervals, and often ho’d, the better the Ground does maintain them; the last Crop is still the best, without Dung, or changing the Sort of Plant; and this is visible in Parts of the same Field, where some Part has a first, some other Part a second, the rest a third Crop growing all together at the same time; which seems to prove, that as the Earth is made by this Operation to dispense or distribute her Wealth to Plants, in Proportion to the Increase of her inner Superficies (which is the Pasture of Plants); so the Atmosphere, by the Riches in Rain and Dews, does annually reimburse her in Proportion to the same Superficies, with an Overplus for Interest: But if that Superficies be not increased to a competent Degree, and, by frequent Repetitions of Hoeing, kept increasing (which never happens in common Husbandry) this Advantage is lost; and, without often repeated Stercoration, every Year’s Crop grows worse; and it has been made evident by Trials, which admit of no Dispute, that Hoeing, without Dung or Fallow, can make such Plants as stand in wide Intervals, more vigorous in the same Ground, than both common Dunging and Fallowing can do without Hoeing. This Sort of Hoeing has in Truth every Year the Effect of a Summer-fallow; tho’ it yearly produce a good Crop. This is one Reason of the different Effects Plants have upon the Soil; some are said to enrich it, others to burn it, _i. e._ to impoverish it; but I think it may be observed, that all those Plants, which are usually ho’d, are reckoned among the Enrichers; and tho’ it be certain that some Species of Plants are, by the Heat of their Constitution, greater Devourers than those of another Species of equal Bulk; yet there is Reason to believe, that were the most cormorant Plant of them all to be commonly ho’d, it would gain[58] the Reputation of an Enricher or Improver of the Soil; except it should be such, as might occasion Trouble, by filling it full of its shatter’d Seeds, which might do the Injury of Weeds to the next Crop; and except such Plants, which have a vast Bulk to be maintained a long Time, as Turnep-Seed[59].
