Absorption rate of clay (Helen)

The absorption rate of clay seems to vary a little depending on the source.

Infiltration rate of

We could perform a water absorption test to determine what type of soil we currently have. The following procedure is from the University of Wisconsin – Madison Arboretum site

Procedure: Perform the following infiltration test at each location selected.

  1. Dig a hole 6 inches deep by 6 inches in diameter.
  2. Fill hole with water and let stand for one hour.
  3. Refill hole with water. Measure depth of water with a ruler.
  4. Let stand 1 hour. Then measure the depth again.
  5. Use the following chart to determine soil types based on the rate at which water soaks into the soils.

Soil type: Rate

  • Sand: 1.5 inches/hour or 4 hours total
  • Silt :1/2 inch/hour or 12 hours total
  • Clay 1/3 inch/hour or 18 hours total
