Humeston, IA
In the north central part of the field, was there a previous farmstead there, or perhaps across the road? The high P and K levels there would suggest so...
Also, it would be safe to assume the low pH areas are your Clarion ridges, and the rest is Canisteo? I love northern Iowa soils and their repeatability!
