The reason I would put turnips in with it, is that they naturally put nitrogen back in the ground. This will keep your soil in good standing year after year without adding chemicals.
Has anyone used one of these? Seen one in use? Heard good/bad about them?

I would think in that situation you might be better off casting into the shallows. Pulling spinners/lindy's under planer boards that shallow is going to be tricky to do imo. Snags!
I mostly use my planer boards for cranks.
