mention the characteristics features of the following loam, clay, silt, sand
Answers
Answer:
The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture. A clay loam texture soil, for example, has nearly equal parts of sand, slit, and clay. These textural separates result from the weathering process.

Answer:
Types of Soil
Soil is classified into four types:
Sandy soil.
Silt Soil.
Clay Soil.
Loamy Soil.
What is Loamy Soil?
Loamy Soil is the mixture of clay, sand and silt soil which consists of additional organic matter and is very fertile compared to other types of soil. It is well suited for cultivation as the plant roots get a sufficient amount of water and nutrients for their growth and development
What is Clay Soil?
Clay or clay soil is mainly composed of the smallest particles of soil, which are densely packed with very little or no airspace and they effectively retain water. This soil is not suitable for growing plants as it is harder for moisture and air to penetrate into the soil
What is Sandy Soil?
Sand or sandy soil is formed by the smallest or fine particles of weathering rocks. This soil is known as the poorest type of soil for agriculture and growing plants as they have very low nutritional value and poor water holding capacity.
Which soil is called the gardener’s best friend?
Loam or Loamy soil is called the gardener’s best friend.
Which crop can be grown in Loamy soil?
Loamy soil is suitable and the best soil for growing crops such as cotton, oilseeds, sugarcane, wheat, pulses, jute and other vegetables
What are the different types of Soil?
There are different types of soil and are categorized mainly based on the size of the particles and the percentage of particles present in it—the three primary types based on its texture: Sand, Loamy and Clay.
Other types of soil based on the percentage of particles, resulting in more compound types of soil: loamy sand, sandy clay, silty clay, etc. Apart from these, soils are also classified based on their colour- Red soil, Black soil and Brown Soil.
Loamy Soil
Loam is the fourth type of soil. It is a combination of sand, silt and clay such that the beneficial properties from each is included. For instance, it has the ability to retain moisture and nutrients; hence, it is more suitable for farming. This soil is also referred to as an agricultural soil as it includes an equilibrium of all three types of soil materials being sandy, clay, and silt and it also happens to have humus. Apart from these, it also has higher calcium and pH levels because of its inorganic origins.
Clay Soil
Clay is the smallest particle amongst the other two types of soil. The particles in this soil are tightly packed together with each other with very little or no airspace. This soil has very good water storage qualities and makes it hard for moisture and air to penetrate into it. It is very sticky to the touch when wet, but smooth when dried. Clay is the densest and heaviest type of soil which does not drain well or provide space for plant roots to flourish.
Silt Soil
Silt, which is known to have much smaller particles compared to sandy soil and is made up of rock and other mineral particles, which are smaller than sand and larger than clay. It is the smooth and fine quality of the soil that holds water better than sand. Silt is easily transported by moving currents and it is mainly found near the river, lake and other water bodies. The silt soil is more fertile compared to the other three types of soil. Therefore, it is also used in agricultural practices to improve soil fertility.
Sandy Soil
The first type of soil is sand. It consists of small particles of weathered rock. Sandy soils are one of the poorest types of soil for growing plants because it has very low nutrients and poor water holding capacity, which makes it hard for the plant’s roots to absorb water. This type of soil is very good for the drainage system. Sandy soil is usually formed by the breakdown or fragmentation of rocks like granite, limestone and quartz
