Mustard produces significantly more glucosinolates than other brassicas, which biofumigates the soil during decomposition, proving to be toxic to many soil pathogens and pests.
To best utilize these glucosinolates, mature green vegetation should be turned into the soil. In no-till operations you will still benefit from having this species for this use.
When allowed enough growing season, brown mustard stem residue can remain erect throughout the winter months, aid in capturing snow to help build moisture in the soil profile.
Growing mustard in a potato rotation was observed to increase tuber quality and yields similar to that of chemically fumigated fields. Other documented effects of having mustard in your rotation is suppressing potato early dying and reduced root rot in pea rotations.
Some customers are concerned that these mustards are difficult to control like their wild cousins but actually they can be easily terminated with many commonly utilized herbicides.
