Short answer. You do. The proceeds of the alienation must be turned over to the owner-spouse, and the sale automatically ends his administration over that property. The money does not become his by having passed through his hands, and it does not become community property either.
What the law says
The alienation of any exclusive property of a spouse administered by the other automatically terminates the administration over such property and the proceeds of the alienation shall be turned over to the owner-spouse.

The proceeds stand in for the property
The rule follows from what exclusive property is. The land was yours; what was given to your spouse was management, not ownership. When the property is converted into money the money takes its place, and it is turned over to the owner-spouse — a duty, not a matter for negotiation. The administrator is accountable for it in full, not for a share of it, and cannot set off against it his own effort, the years he spent looking after the land, or expenses he did not disclose at the time. If part of it has been spent, the obligation to account for the whole is unchanged.
Administration ends by itself
The other half of the sentence is easy to miss and useful to know. The alienation automatically terminates the administration over that property — you do not have to revoke anything, and there is nothing left to revoke, since the thing administered is gone. Where the administration was recorded in the registry of property, as a transfer of administration is required to be, that record should be dealt with so it does not continue to advertise an authority that has expired. If your spouse administered several properties, only the one sold drops out; the rest continue under his management.
Whether the sale itself was valid is a separate question
The article assumes an alienation has happened and says what follows; it does not confer the power to make one. An authority to administer is not an authority to sell, and if your spouse sold without the power to do so, you may be arguing about the transfer itself and not merely about the money. Those are different claims with different targets — one against the buyer, one against your spouse — and they can be inconsistent. Deciding which you actually want is the first thing to settle, because pursuing the proceeds tends to signal acceptance of the sale.
Trace the money while the trail is warm
Proceeds are recoverable in proportion to how well they can be traced. Get the deed of sale and the price stated in it, the buyer's proof of payment, and the account into which the money went; then follow what left that account and when. If any of it was used to buy something else, identify the something else. Gather too the instrument by which you gave the administration and the documents showing the property was exclusively yours, since your spouse's first line of defence is usually that the property was not exclusive at all.
