How soils form is a question with a complex but very interesting answer. Over the years, waste, materials and particles are deposited in one region. Over time, the action of wind, rain and heat join with the prolonged work of fungi, bacteria and other microorganisms.
Now that you know how soils are formed, how about delving into their composition and types? We separated the main components:
The sand is made up of small grains of rock and minerals smaller than 2 millimeters in diameter. The predominant mineral in its composition is quartz. In addition to being found on beaches and rivers, sand is present in the composition of many soils and is what gives the feeling of roughness.
Clay is an important element of how soils form. It is responsible for the viscosity sensation of soils. Its grain is much smaller than that of sand, not exceeding 0.002 mm.
Its name is less well known, but silt is responsible for the silky feel of the soil. Its particle is intermediate between clay and sand and varies between 0.002 and 0.05 mm.
In addition to sand, clay and silt, many soils have pollutants. It is the result of improper handling, contamination by industries or household waste, contaminated water sources, among other reasons. In all cases, this poses a very serious problem as it prevents its use and can cause serious environmental damage and pose many risks to people’s health. The soil is fundamental to the basis of human food, enabling agriculture and livestock. It is also used in various industries and is still essential for urbanization and sustainable growth. This is why the soil decontamination process is so important.
The disposal of contaminated soil is a combination of techniques and methods used to remove toxins from soil or water. Remediation and disposal of contaminated areas allows protection of the environment and humans.
