S.E. Iowa | My recommendation would be to use a drainage mole. basically its a tear drop or ball shaped piece of metal 4-6-inches in diameter attached to a sub soiler type shank that is pulled though the ground at a 2-3 ft depth. leaves a tunnel in the ground that allows water to drain through. Even though the tunnel only last for 2-3 years before having to redo it, many thousand of acres were drained using a mole in the United States. | |

Field drainage with gravel instead of tubes?
