Ablaqueátion. [ablaqueatio, Lat.] The act or practice of opening the ground about the roots of trees, to let the air and water operate upon them.
Trench the ground, and make it ready for the spring: Prepare also soil, and use it where you have occasion: Dig borders. Uncover as yet roots of trees, where ablaqueation is requisite. Evelyn's Kalendar.
The tenure in chief ought to be kept alive and nourished; the which, as it is the very root that doth maintain this silver stem, that by many rich and fruitful branches spreadeth itself into the chancery, exchequer, and court of wards: so if it be suffered to starve, by want of ablaqueation, and other good husbandry, not only this yearly fruit will much decrease from time to time, but also the whole body and boughs of that precious tree itself, will fall into danger of decay and dying. Bacon's Office of Alienations.
