Explaination for translatable string "harvest"

[Lucian Adrian Grijincu <lucian grijincu gmail com>]

Could you please add a comment near translatable strings that contain
"harvest" explaining what it means (those comments should end up in
.po files).

It's not a common computer metaphor, and translations for this can
easily get ridiculous.

Thank you,
