Driftless SW Wisconsin | In drilling beans after stripped 30" corn it would seem obvious on a low P soil that there will be drilled 8" beans placed where there is not P from the previous stripped corn. Broadcast would obviously have some P near all of the drilled beans.
We are seeing that over multiple years of moving back and forth in strips fertility evens out.
Better yet is stripping 30" beans between 30" corn rows with applied fertilizer specifically for the beans. We have customers who are seeing significant financial advantage to fertilizing beans rather than just planting them with no fertilizer supposedly living off the excess from the corn crop.
Strip till let's you put down what the coming crop needs, when and where it needs it. Fall placement of K especially makes it more available in the spring, or so I am told. If you are in a low K soil then maybe try to get it down in a strip in the fall.
This also brings up the point of depth of fertilizer placement. P especially contributes to early root development. Having it 8 or 10" deep somewhat delays the time for the roots to get to the needed fertilizer.
An interesting topic with many different possible interpretations.
