  1. Precision Technology Use of Ag. Subsurface Tile Drainage Systems Samantha Ambrose SOIL 4213

  2. Introduction • What is tile and how does it work? • The old days • Today’s technology

  3. What is tile? • Originally clay pipes • Slotted, flexible plastic tubing • 7.5 to 46 cm diameter • Removes excess water from the root zone 24 to 48 hours after a heavy rain Image from: http://www.abalonwpg.ca/weepingtile.htm

  4. How does it work? Header tile Lateral tile Image from: http://www.extension.umn.edu/distribution/ cropsystems/dc7740.html Adapted from: http://www.omafra.gov.on.ca/english/engineer/facts/10-091.htm Tile outlet Open ditch

  5. Installation Variables • Topography • Crops • Soil texture • Spacing • 15 to 40 meters • Depth • Placed 0.9 to 1.2 meters

  6. Installation-Then • Clay pipe: 5,000 BC • Hand tools used for installation • 1906: 3 ft deep, $2.42 per 100 ft

  7. Installation-Then • Machine Trenching • 1906: $1.24 per 100 feet http://www.ag.ndsu.edu/waterquality/documents/History_of_Drainage.pdf

  9. Installation-Now • Contractors • GIS/AGPS • Soil maps • Contour maps • Aerial photographs • Field history is essential www.heartlandaggroup.com

  11. AGPS-Pipe Pro • Calculates tile depth and slope during installation • RTK GPS uses Vertical Curve Technology (VCT) • Real time guidance with grid control that reduces flagging

  12. Summary • Tile drainage installation has come a long way in the past 100 years • Potential for more improvement with new technology
