2 Methods of assessing soil texture

what is soil texture?

Soil texture is one of the physical properties of soil along with soil structure, soil color, soil temperature, soil porosity, and others.

2 Methods of assessing soil texture

Soil texture can be defined as the coarseness or fineness of the soil determined by the relative proportion of soil particles of different diameters.

The size of soil particles can make the soil coarse-textured, medium-textured, and fine-textured.

The texture of the soil can be assessed by either sense of feel method or particle analysis method. 

Methods of assessing soil texture

Sense of feel method

this method is done in the field in which soil sample is rubbed, preferably in wet condition between fingers, and may give any of the following results;

  • gritty feel – this imply the soil is of coarse texture as its particle are large in size and is recognized as sand soil.
  • flour feel – the soil is slightly fine or medium texture as its particles are medium in size and is recognized as silt soil.
  • plastic feel – the soil is of fine texture as its particles are quite small and is known as clay soil.

Particle analysis method

this method is more accurate as it is done in the laboratory and involves recognizing the texture of the soil by measuring the size of soil particles in the soil sample.

Diameter of the particle (mm)Name of soil
Less than 0.002clay
0.002 – 0.02silt
0.02 – 0.2Fine sand
0.2 – 2Course sand
2 – 20Fine gravel
20 – 200gravel
