What Is Soil? How Does soil get formed?

 What is soil?

 Clay is a mixture of minerals.

How does soil get formed?

Soil is formed by breaking and erosion of the upper crust of the earth.

Type of mineral

 Minerals can be divided into two types, first on the basis of origins and second on the basis of utility.

Origin

 On the basis of origins, the minerals are divided into two parts, the first is the organic minerals and the second these are mineral minerals.

Organic minerals are those whose source is trees, thus the minerals obtained in this way are called organic minerals.

 And these organic minerals are the minerals that are found in other things besides the tree, the mineral obtained from other things except the tree is called these organic minerals.

On the basis of utility, we sit the mineral in two parts, first primary mineral and second mineral.

Utility

Primary minerals are minerals in which the real game is silicate equivalent of silica + oxygen.
Ferrum aluminum, magnesium, calcium are found in silicates
Primary minerals do not play any special role in the life of tree plants. If the primary mineral is not there, then the tree plants can do their work and survive.

Secondary minerals are also called soil minerals and it is also called mineral oxide. Second minerals have an important contribution to the life of tree plants. The more soils are the second minerals in the soil, the more fertile the soil will be and the more soils in that soil. More plants will grow, this means that the second mineral plays a very important role in making the soil fertile and for the plants to survive and grow.

Types of soil

We can divide the soil by texturing and Indian Agricultural Research Center in 2 ways.

Depending on the texture, we can divide the soil into three parts.
Sand, silt, and clay.

Indian Agricultural Research Center has divided the soil into 8 parts...

1. alluvial soil 
2. black soil
3. red soil 
4. laterite soil 
5. mountain soil 
6. desert soil
7. marshy soil 
8. gravelly soil

Based on the texture, we have divided the soil into three parts, one sand soil two silt 3 clay.

The size of sand-clay particles is larger than the particle of all types of soils because the size of the particle is large, it has high porosity due to which it has very low water retention capacity, so this type of soil contains millets We can grow types of crops, in this type of soil we can grow gram dal maize mustard millet i.e. coarse grains.

The size of the clay particle is smaller than the particle of all types of soils, the size of the particle is very small in clay, so it has less porosity and this soil has a very high water-holding capacity, so this type of soil In those crops which require more water, those crops are grown in this type of soil like rice sugarcane jute.

Silt soil is formed after mixing of sand-clay particles and clay soils where the mixture of sand clay and clay soil goes where the silt soil goes. In this type of soil, there is no loss even if the water gets less like Wheat, Barley.
