Silt Soil
In the case of silt soil, rock particles are much smaller in size when compared to sandy soil. Silt soil mostly consists of rocks and mineral particles. The texture of the soil is smooth and the quality is fine. It has a soapy, silky texture. Silt soil has a higher water-holding capacity than sandy soil. Silt soil is transported by the wind currents and the waves, so they are mostly found in river banks, and lakes.
Silt soil is very fertile and is considered one of the best for the growth of vegetation. Silt soil is the most fertile in comparison to other types of soil. There is a huge amount of organic material present in this soil which supports plant growth. This type of soil is generally used for agricultural purposes. It is formed when rocks are weathered, or worn away by water or ice. These particles further get smaller in size when they are rubbed against other rocks in the water stream. Almost 35-40 percent of the total soil in India is Silty soil, which explains the large agricultural sector of our country. The banks of all the rivers contain this soil like the Ganga Brahmaputra basin.
Types of Soil : Sandy Soil, Clay Soil, Slit Soil and Loamy Soil
Soil refers to a broad term that means a loose layer of earth that covers the surface of the earth and includes disintegrated rock, inorganic and organic materials, and humus. Changing the form of soil from rock to soil takes 500 years or even more.
When different forces act upon the rocks, they break down into smaller parts to form “soil”. The forces also include the force of wind, water, and salt reactions. There are mostly 3 stages of soil, namely:
- Solid soil
- Soil with air in the pores
- Soil with water in the pores
The types of soil are determined based on texture, proportions, and different forms of mineral and organic composition.
