Be very careful with manipulation if the rice grows back. A few years back, we went out a month before season to fix up our pit. The rice had grown back after harvest and had headed back out. There was rice everywhere and I was real excited. Two weeks before season started, our farmer went in and rolled the stubble down in front of our pit. Week before season started, feds came in and flagged every field in the area that had the stubble rolled with all the volunteer rice. Said it was not normal agricultural practice, and we had to move fields. Farmer had to disk the rolled area until there was no more evidence of rice left before it could be hunted.
