For the ribbon test, take a small amount of moistened soil and squeeze it between your fingers.

If the soil forms a long ribbon, it indicates high clay content.

If the ribbon crumbles easily, the soil may contain more sand.

For the jar test, fill a clear jar with a soil sample and water.

Shake the jar vigorously for a few minutes, then let it sit undisturbed.

Over time, soil particles will settle into distinct layers.

The sand will settle at the bottom, followed by silt, and clay will remain suspended longer.

Measure the height of each layer to determine the percentage of each soil particle size.

After conducting these tests, compare your results to the soil texture triangle.

Use the proportions of sand, silt, and clay to classify the soil texture.
