How do you measure clay content?
Wet the dirt by kneading it in your hand until it’s uniformly hydrated and you don’t have dry crumbly patches or runny dripping mud. If the moist soil feels sticky and continues to stick to your hand without falling out when you turn it upside-down, that’s a great indicator that the soil has a decent clay content.
How do you find the percentage of clay in soil?
Once the soil has settled, it’s time to determine the percentage of sand, silt, and clay relative to the total soil level. To calculate the percentage, divide the depth of each layer of soil by the total soil depth in the jar, and multiply by 100.
How do you test soil quality?
Use a shovel to dig up about 1 cubic foot of soil. Put the soil on a piece of cardboard, break it apart, and look for earthworms. If your soil is healthy, you should find at least 10 earthworms! If your soil has fewer than 10 worms, add more organic matter—compost, aged manure, leaf mold.
How can you tell the quality of clay?
The three important general characteristics to take note of are shrinkage, absorption and warping/slumping. Other important qualities to note are color, texture, plasticity and hardness. Some results are determined with visual and touch tests while others require simple formulas.
How can you identify clay?
Wet clay is recognized by its soft, plastic consistency. Clay is more easily recognizable when it is wet, then it displays the soft, plastic consistency we associate with clay. Be aware when walking around on damp ground, looking for slick and sticky spots where clay is located.

- Pure silt soils are rare, especially in gardens.

How do you fix heavy clay soil?
Amending your soil properly can overcome heavy, compacted clay and get it back on track for healthy lawn and garden growth. Adding materials such as organic compost, pine bark, composted leaves and gypsum to heavy clay can improve its structure and help eliminate drainage and compaction problems.
Is it OK to build a house on clay soil?
Clay soil isn’t particularly good for construction because it’s susceptible to moisture fluctuation. It expands when it’s moist and contracts when it’s dry, resulting in uneven floors and fissures in the foundation. Clay creates poor soil support, and you’d need a proper structural foundation to keep it stable.
