Definition of "unleached" [unleached]

  • Not leached: as applied to wood-ashes, implying an important distinction, since such ashes when unleached, or not exhausted of soluble matter by the action of water, have notable manurial value on account of the potash salts which are present; but the value on this account is almost entirely lost after leaching.
