| hi JrDitchDigger,
Unless your fields have VERY low weed seedbanks because of aggressive long-term chemical weed control, I think you will experience a significant flush of weed germination as the soil warms up.
I have a few questions:
when did you plant the cereal rye?
Also, how mature was the rye when you rolled it? Had it started shedding pollen? Had it finished shedding pollen?
******************************************************************************
At the WIU Organic Research Farm, we normally don't roll/crimp until at least a week after the rye (or triticale) has finished shedding pollen.
Regarding the rye still standing in your no-till soybeans, in my experience, most of it eventually falls down and if there is much precipitation, a substantial portion of the rye will germinate during the summer and then die under the soybean canopy.
During very dry seasons, we have a lot more rye volunteer in the fall.
We have not had problems growing corn following organic no-till soybeans as long as we used enough manure to supply adequate N and terminated the volunteer rye when it was relatively short (e.g., less than a foot tall).
