To Determine Soil Texture

Step 3 (Refine initial soil texture classification from Step 2 for relative amounts of sand and silt) Wet a small pinch of the soil in your palm and rub it with a forefinger.

If the soil:

  • Feels very gritty, go to E
  • Feels very smooth, with no grittyfeeling, go to F
  • Feels only a little gritty, go to G

E. Add the word sandy to the initial classification.

Soil texture is (check one):

  • sandy clay,
  • sandy clay loam,
  • sandy loam

sandy clay loam, sandy clay, sandy loam


Soil Texture is complete.

 

F. Add the word silt or silty to the initial classification.

Soil texture is (check one):

  • silty clay,
  • silty clay loam,
  • silt loam
Soil Texture is complete.

Soil Texture is complete.

 

G. Leave the original classification of (check one):
  • clay,
  • clay loam,
  • loam
