Ribbon Test As An Indicator of Soil Type

APES-O$CKMO

The ribbon test is a method for estimating soil texture. A moistened clump of soil is squeezed between the thumb and fingers. The length of ribbon that holds together is a predictor of the relative amounts of sand and clay in the soil. With 20% or more clay content, one would expect a ribbon to be two inches or longer. Sandy soil will generally produce a one inch or shorter ribbon.

What can be concluded about a soil sample that produces a 0.5 inch ribbon using the ribbon test?

A

High nutrient content.

B

High water-holding capacity.

C

Contains a high percentage of organic matter.

D

Low drainage capacity.

E

High permeability.
