Question

Out of sand, silt and clay which particles will settle down first in graduated cylinder during texture determination and write down the name of the instrument used for texture determination.

Answer 1

Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil.

To find the texture of a soil sample, first separate the fine earth* , all particles less than 2 mm, from larger particles such as gravel and stones. Fine earth is a mixture of sand, silt and clay. You must be sure to use only fine earth to perform the following field tests.
