Reference for Ketubot 160:4

והלכתא בעל שמכר קרקע לפירות לא עשה ולא כלום מ"ט אביי אמר חיישינן שמא תכסיף רבא אמר משום רווח ביתא

And the law is that if a husband sold [his wife’s] field for its usufruct his act has no legal validity. What is the reason? Abaye said: Lest the land deteriorate. Raba said: In order [to safeguard] the comfort of his house.
