[9] The ancient custom in the Land of Israel was to mark the ground surrounding Orlah-plantings with crushed potsherds (חרסית), so as to signify that the fruit grown on the trees are forbidden to be eaten until after the first three years.
And anybody who says that there is no (prohibition) of orlah outside the land of Israel will not (merit to have) either a great-grandchild or grandchild who cast property ownership in the lot of the congregation of HaShem.

[20] Papain, (a "second crop" enzyme extracted from the papaya peel, used in beer, biscuits, and as a digestive aid) is likewise under rabbinic scrutiny as a dilution ratio of 200:1 (200 non-orlah fruit to 1 part orlah) is required to permit orlah, essentially prohibiting benefiting from this enzyme.
