Plowing Weeds with 4020 Tractor Ahead of Beans

We're doing this on a small part of the field to try and bury any weed seeds well below the surface of the soil. Plowing is out of fashion, but we wanted to see if it would help suppress weeds in the cash crop of beans.
I think the majority of the weeds shown in the video are either pennycress or pepperweed (Lepidium densiflorum).
The tractor is pulling a three bottom plow.

Quiero enterrar las semillas de malezas debajo de varios centímetros de tierra y el disco no llega lo suficientemente profundo
