Sugarcane around Kaplan.

[Duck Butter]

Plenty of wildlife in sugarcane fields, one of the few places you can actually see quail

Also, plenty of chemicals used in rice farming as well, so the chemical comment is null and all those chemicals and wastewater gets drained off several times a year and goes right down the bayou, and they use a TON of water to pump those fields and many of them pump from groundwater = drinking water
And diesel prices to pump those fields is pretty high

Sugarcane farming seems a lot less intensive than rice
