Clays have a large specific surface, often predominantly negatively charged, that retains nutrients against leaching and reacts with hydrogen and aluminium ions, while buffering the soil against extreme pH changes. The clay itself may be a source of plant nutrients when it degrades.
Why is clay soil important?
As soils, they provide the environment for almost all plant growth and hence for nearly all life on the Earth’s surface. They provide porosity, aeration, and water retention and are a reservoir of potassium oxide, calcium oxide, and even nitrogen.
What are the uses of clay soil?
Because of these properties, clay is used for making pottery, both utilitarian and decorative, and construction products, such as bricks, wall and floor tiles. Different types of clay, when used with different minerals and firing conditions, are used to produce earthenware, stoneware, and porcelain.

What are the qualities of clay?
What are the characteristics of clay?
- Plasticity – sticky, the ability to form and retain the shape by an outside force, has a unique “crystal” structure of the molecules, plate like, flat, 2 dimensional, water affects it.
- Particle size – very tiny – less than 2 microns, 1 millionth of a meter. (
What is clay made of?
Clay minerals are composed essentially of silica, alumina or magnesia or both, and water, but iron substitutes for aluminum and magnesium in varying degrees, and appreciable quantities of potassium, sodium, and calcium are frequently present as well.
Can I put topsoil over clay?
Important Note: Do not roto-till clay after a heavy rain because it will destroy the clay structure, further compacting the soil. An easier method, if possible for you, is to simply apply 6 inches of quality topsoil over your existing clay soil and plant your lawn in that.

What is clay and its properties?
The small size of the particles and their unique crystal structures give clay materials special properties. These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability.
How do you identify clay soil?
If the soil falls apart when you open your hand, then you have sandy soil and clay is not the issue. If the soil stays clumped together and then falls apart when you prod it, then your soil is in good condition. If the soil stays clumped and doesn’t fall apart when prodded, then you have clay soil.

What is the important of clay?
Clay is a kind of material that is formed through the processes of weathering and erosion. Clay has the smallest particle size of any soil type. This also means that clay retains water well. Clay is an important part of soil because it contains nutrients that are essential to plant growth.
