I don’t think it would…Not unless you already an issue to begin with..Just keep a root system in place at all times. When you terminate one root system then another is coming in behind it to take its place. Even though it’s been terminated, the cereal grain roots in Joe’s garden are still stabilizing the top soil right now and helping to maintain the “structure” of his soil. They serve as framework basically…….It would be a good idea to add in some radishes into the cover crop mix along with some clover. The radishes would take that root framework deeper into the soil profile and the clover would provide a little extra N to compensate for what the biomass will tie up as it begins to decompose. Vetch would be another option for a legume.

It probably wouldn't be a bad idea to dust the whole garden with a little 34-0-0.....
