Unless things have changed in the last couple of years, it's still a thing down south
So much is watered down the row, you could plan on plowing twice and not worry about bedding before planting.
Corn will turn purple on ground that has been flood irrigated for rice. You have to plow it to get oxygen to the roots. In small beans and sandy ground your fighting blowing sand when it gets dry so plowing is still kind of a thing even when it's not needed.
California is a different animal. It's still chisel plows and offset disc's before planting and D8 to D10's with rippers when replanting an orchard.
