Soil Analysis

Regloth

soft part of soil

Bedrock

hard part of soil

Using the soil texture ternary diagram, determine the type of soil given the following proportions (in mass):
• Silt: 10%
• Sand: 50%
• Clay: 40%

sandy clay loam

A soil is analyzed through sieves of different pore size. The table below tells you the total mass of soil analyzed is 2.8g. There is 0.3g of soil finer than the 50 microns sieve. Calculate the percent finer (inmass %) that is associated to the sieve of pore size 50 micrometers

.3/2.8 x 100= 10.71%

Which soil type is composed of 91% sand and 9% clay?

sand

What type is the soil for which the mass analysis is shown below?
Sand mass: 2.85g = 85%
Silt+Clay mass: 0.5g = 15%

Loamy sand

Gravel

rock fragments and pebbles 2 millimeters and up

Sand

the coarsest soil, with particles 2.0 mm-50 µm in diameter.

slit (soil)

fine soil 50 micrometers to 2 micrometers

clay

the finest soil, made up of particles that are less than 0.002 mm (2µm) in diameter.

loams

Soils containing a mixture of clay, sand, silt

Munsell notation
