Ozaukee county has many farm fields with high clay content or highly organic soils. So how do farmers make a field with lots of clay or organic matter possible to farm and grow a crop? The answer is drain tile, which can either be a plastic tube or concrete cylinders. Both have the same goal which is to remove excess water from the soil horizon which will be planted with seed for a future crop. However, there are rules set in place to protect natural areas, such as wetlands from being drained intentionally or accidentally.
