The lack of left over N is definitely holding back the growth in our cover crops.
Noticed this strip after the winter wheat trial plots. About 2ft wide it had no wheat in it all year so no crop to remove the applied N. The Phacelia is much greener and bulkier there.
Also less stubble there which would probably lock up some N temporarily while it breaks down.
The wet spring would have washed out a lot of N.
In ways, I’m glad to see a lack of left over N, it means that it wasn’t wasted.
