Belleville, Ontario | There are a whole lot of people with more experience than I, but for residue concerns, take a sample of soil and do a bioassay on it (grow some raddish in a pot in the house under good care). The side benefit is your wife will finally think you have taken an interest in the house plants. Do not dump out her spider plant to do this, get your own pot (personal experience) Mustards are very sensitive to atrazine and pursuit. Canola is used by many labs as the bioassay 'sensor'.
I would try some sorghum/sudan grass. It is more drought tollerant, tollerant to atrazine, and has a very netted root system. It will suck up N like crazy, too. Maybe try some in the mix. Nothing like tap rooted cover crops, though.
