Farmers who do not want the length of their growing season limited by standing water or overly moist soil conditions rely on professionally installed tile drains to start their growing season on time! Kiesow, Inc. has over 45 years of experience helping farmers throughout Central and Southern Wisconsin extend their growing season and increase their crop yields and generate higher revenues using drainage ditches and field tiling. We use a Global Positioning System (GPS) to survey your fields and determine the optimum location and pitch of drainage tiles.
