Study Notes

Experiment: Soil Water Absorption and Retention

Two glass tubes are prepared, each with two holes and a muslin membrane at one end.
Sandy soil absorbs water rapidly and loses it quickly due to weak attractions between its large particles.
Clay soil absorbs water slowly and retains it for longer periods due to strong attractions between its small particles.

Soil Texture:

Soil texture refers to the relative proportions of sand, silt, and clay particles within a soil sample.

Determining Soil Texture:

A soil texture triangle is used to determine the texture of a particular soil.
To read the triangle, a line is drawn from each of the three components (sand, silt, clay) towards the opposite side of the triangle.
The point where the lines intersect represents the soil texture.
Each component (sand, silt, clay) must be represented by a line that is parallel to one side of the triangle.
The head of the formed angle (the point where the lines intersect) represents 100% of the specific component.
