Fields of yellow flowers

probably ragwort or buttercup Both annuals they pop up in early spring in harvested fields

Been seeing some buttercups in fields in north Louisiana. Usually don’t pop up til March

They’re for spraying with 2-4-D. They’re weeds. They pop up in fields and pastures when temps start warming in January,February. They usually die off when temps get above 90F. They don’t serve any agricultural purpose other than to give the herbicide dealers some business.

I think that’s how the town of Golden Meadow down in South Lafourche got it’s name.
Seemed like I heard that when I was a child.

Rapeseed = canola

As stated by Ron Cheramie above, most likely buttercup. LINK

It’s a combination of cane farmers that didn’t listen to their consultants and abnormally wet weather that’s keeping the sprayers out of the fields.

One comment made just Friday- “I bet you wished you would have put Command out like I told you to- that shite looks like a damn golf course with all that grass’”

It ain’t buttercups.

Now how would you know this, OP didn’t include a photo or or closeup of the flowers. So I’m only speculating as well. But based on OP description of what he saw, location, and time of year, I had fields of what he described in a pastures next to my office in Baton Rouge. Out of curiosity myself of what this plant was, I sent photos of of these fields of yellow flowers, and close up photos of the individual flowers to the Ph.D. weed specialist professor in the LSU AgCenter and he ID’d the plants as buttercup, a cool season annual common in open pastures/fields in south Louisiana.

Now as a kid growing up in south Louisiana, buttercups were referred to a plant with a pink flower with a center (stamens) covered in yellow pollen. However, those are are actually white evening primrose.

“Pee-pee” flowers
