southern MN | As the others say, what heppens is there are wet spots in the side hills. But you don't know they are there, because you have to wait for the low spots to dry out. By the time the bottoms of the field go, the sides you can mud through as well.
Once you get the bottoms dried out with tile, it doesn't take long to realize the whole filed had wet aras that really hinder farming. Just didn't notice them before.....
The forest for the tree sort of thing.
Plan for it with big enough tile mains to start with, or figure you will end up running a second main in a few years to handle the rest of the field after the bottoms are drained. It is difficult to get it to work right on a field that has shallow drainage for a long distance; with several hills along the way that will need draining too. This shows up much more so in clay soils where the water holds up or moves along secret soil layers..... You end up with 2 different situations, hard to make one main deal with it all and we _always_ undersize that first main.
