Soil Infiltration rate


In use from 2015-01-01


  1. Materials:
  • Stainless Steel Cylinders 28.5cm ID x 22.8cm Ht
  • Ohaus Ranger 3000 Scale
  • Mariotte-syphon (25L carboy with spigot, PVC pipe, silicon epoxy, flexible tubing, vacuum grease)
  • 20L carboys for water bringing well water to air temperature.
  • Plastic driving plate
  • Rubber mallet
  1. Protocol:
  • Infiltration rate is measured using a single-ring infiltrometer method.
  • Cylinder is driven 5cm with a plastic driving plate and rubber mallet into the soil and allowed to settle for at least 24 hours.
  • The soil inside the cylinder is flooded with water at air temperature.
  • A constant water depth of 10cm in the cylinder is maintained through a Mariotte-syphon.
  • The weight of the water in the Mariotte-syphon is measured every 10 seconds using a scale until the rate becomes constant.
  • Infiltration rates are estimated from the linear portions of the measurements in each location.
  • Linear regression is fitted to the linear portion and used to determine steady infiltration.
  1. Notes:

In row-cropping treatments T1-T5, rates are measured in between soybean and poplar rows. Tire tracks and paths are avoided in all treatments.
