What is clay soil and the properties of clayed soil. The definition of clay soil. Clay soil is is a situation where in the sample of soil has more proportion of clay than the rest of soil type. So a soil is said to be clayey if the proportion of clay in a sample of soil is very high
One of the major properties of clayed soil is that the relative size of a clay particle is less than 0.002 mm.
Clayed soil is heavy in nature so it is very hard to work on
One major major importance of clay soil is the use of it to produce clay materials such as ceramic wares
Clay is also used to produce local pot used for cooking and storing water in some communities in Nigeria
Without wasting time on this subject let us go sit down and look at the importance of clay in properties of clay how to recognise clay soil
properties of Clay soil
Clayed soil particles are fine powdery and smooth when dry
The particles of clay are sticky and moldy when wet
One great aspect of clay soil is that the particles are tightly bound together with little spaces
the physical structure of a given sample of clay is granola and does not lose water easily
a typical clayed soil sample is poorly aerated with high water-holding capacity
Percolation in clayed soil is low but capillary is high
One good aspect of clayed soil is that it does not support leaching when it contains plant nutrient in high quantity
A typical clayed soil is very hard and difficult to turn around when dry this property of the clay soil is why it is used for the production of pots and ceramic materials that can We Stand 1000 degrees Celsius
Clayed soil can easily form a ribbon or cast when molded
Clayed soil support waterlogging and it is very hard for soil erosion to take place in a sample of soil when you have clay at the greater percentage
One physical property of a typical clay soil is that it has a grey and brownish colour
Note,.. clayed soil can be improved upon through liming
List of all to remember about clay soil is that it is difficult to cultivate crops on it but with the addition of organic manure on a a piece of land it becomes easy to cultivate crops on it

Depending on the size of these soil particles, the texture can range from very porous (sandy) to extremely dense and resistant to water movement (clay).1
Clayed soil is prevalent in many parts of the United States, and it can be very problematic if you are trying to grow a flower or vegetable garden. While some trees and shrubs grow well in clay, most annuals, perennials, and vegetables don’t have roots strong enough to force their way through dense clay. If spring flower bulbs are your dream, forget it—most bulbs tend to rot over the winter in clay soils.
Clay soils can be improved, however. With some background information and a well-designed strategy,
Clay is the smallest of the three soil particle sizes, sand, silt and clay. Clay particles are less than 0.002 millimeters in diameter, feels sticky when wet, and can be formed into a ball. Individual clay particles are not visible to the naked eye and often accumulate in the lower soil layers (the subsoil) as particles travel with soil water or mechanical sorting down through the topsoil.
Topsoil is generally higher in sand, silt, organic matter, and microorganisms. Subsoil is often higher in clay and salts.
Clay particles are plate-shaped and can align in sheets which can compact and form hard soil layers called pans. Landscapes around new construction often have surface soils that are high in clay. This happens when topsoil is removed to build a foundation and the newly exposed subsoil (high in clay) becomes the surface material.
The original topsoil should be replaced when construction is over. It also is important at that time to break up any compacted subsoil so plant roots can penetrate the soil.
What is land in economics?
Land in economics does not only include land surface of the earth but all other free gifts of nature or natural resources like forest, mineral resources, rivers, oceans and atmosphere. Unlike other ction, the supply of land is limited. The reward for land is rent.
Characteristics or features of land
Land is immobile: Land cannot be moved from one geographical location to another
The supply of land is fixed: It is practically impossible for man to increase the quantity of land.
Land is a free gift: Land is given freely by nature.
Land is subject to diminishing returns: When a piece of land is frequently bought under cultivation, it becomes less productive
Variability: The quality and value of land varies from one place to another as some areas of land are more fertile than others
Rent: The reward for land is classified as rent
Land has no cost of production: No cost was involved in bringing land into existence
Land is heterogeneous: No two parcels of land are the same in value or in other characteristic
