The 225th prohibition is that we are forbidden from harvesting s'fichim [uncultivated crops] which grow during the jubilee year in the same way we harvest in a regular year, as we explained regarding the shemittah year.1
The source of this prohibition is G‑d's statement,2 "[The 50th year shall be a jubilee to you in that you may not plant;] you may not harvest crops which grow of their own accord."
