The Importance of soil

Today Niro Online has significant information to bring you about soil. 

Soil is not just dirt; soil is a valuable natural resource that supports life on earth.

What is soil? 

Soil is made of rocks, decayed plants and animals, air, and water. 

The soil is the topmost layer of the earth, or the skin of the planet. It is primarily composed of clay, water, small or large rock particles, minerals, and organic matter. As nearly every form of plant grows in this layer of the ground, and since we know that plants are the ultimate source of nourishment for all living beings, this layer of the planet is accountable for all life on it. Soil is composed of dead and decomposing plant and animal remnants, followed by nutrients and minerals. 

All living creatures need nutrients to grow in order to survive. Minerals are the nutrients found in soil, and they are derived from various types of rocks in the soil. Within the pores of the soil reside both air and water. During the dry season, air is more prevalent in the soil, while during the wet season, water is more prevalent in the soil.

Microorganisms and small animals.

In the soil exist tiny living creatures like worms, termites, ants, gastropods, antheropods, and nematodes.

How Soil is formed?

The majority of the tiny weathered rock particles that make up soil are actually very small broken pieces of fractured rock. Big rocks breakdown into smaller pieces by a process known as weathering and are then moved through erosion and eventually become part of the soil. It can take many years to form soil. Wind, water, and extreme hot and cold temperatures cause rocks to break down over time. 

Soil is not just tiny rocks; it is also made up of decaying plants and animals called humus.  Humus are made up of things that were previously alive. Dead leaves decompose or break down to form a component of the soil, providing nutrients. Humus is a substance that grows on the ground and has a dark color.

Layers of Soil.

There are three different layers of soil. The top layer is known as 'Top Soil', and it is where the plants grow and where the leaves and organic matter decompose. Top soil is where the seeds are planted so they can grow into strong, healthy plants because it is rich in minerals and humus.

It is soft and porous, allowing plants to easily stretch their roots. And worms and rodents make their homes here as well.

It's about two inches thick. Topsoil is made up of rock, minerals, air, and water.

Humus, which provides nutrients to the soil, is also a component of top soil. The amount of each of these varies from place to place.

The middle layer is the subsoil, which is a combination of soil and rocks. Subsoil is hard. It is mainly formed from solid rocks.  Because it is hard and compact, only the roots of large and strong plants can reach this far down, and their efforts are rewarded because this layer is rich in minerals, deposits, and clay. The layer beneath this one is weathered parent rock with no plant or organic matter at all.

The bottom layer is called "Bedrock." It is made up of many layers of rock. This is the hardest layer, and it is made up of the unweathered parent rock that supports all of the layers above it.

There is also soil that is called simply soil, and it has lost its ability to sustain life; it is dead soil.

The color and texture of soil differ from place to place.

Soil types and properties: how are these types of soil formed?

Depending on its properties, soil looks and feels different. There are various types of soil based on their color. Red, black, dark brown, light brown, and other colors are available. The color of soil is determined by the rocks from which it is extracted, and the rocks get their color from the minerals from which they are composed. A rock is made of red iron ore, so the soil formed from it will also be red in color. And it will be high in iron.

Types of Soil.

Soil comes from tiny pieces of withered rock. The size of the rock particles in soil distinguishes it from other types. Based on the size or texture of the soil particles, there are four types of soil.

1. Gravel
2. Sand
3. Silt
4. Clay
5. Loam

1. Gravel

Gravel is large pieces of rocky soil that look similar to babble. It is typically found near valleys and river beds. The soil has many gaps between its particles. Because of the large particle size, this soil cannot hold a lot of water because it is loosely packed. But it can hold a lot of air.

2. Sandy Soil

The sandy soil is gray or brown and has smaller particles than gravel. Sand contains larger particles than the other kinds. It has a gritty and rough texture to it. There are air spaces between the sand grains in sandy earth. Water can rapidly pass through sand because of the air space. Sand does not retain much water, so a sand castle gets washed away by the sea. Sand is found in the deserts and on beaches. Compared to gravel, it can retain more water. Sand is created naturally through the process of erosion, which is the gradual wearing away of something by a natural force such as wind, water, or even just the wear and tear of animal activity. Sand is formed when rocks are gradually whittled down into tiny pebble grains. The long and slow process begins high in the mountains. Over thousands of years, alpine winds and water begin to break down massive mountains, tiny piece by tiny piece. As rocks chip off mountains or break off into rivers, they slowly make their way downstream, eroding and breaking down into even smaller pieces as the water swirls around them. All rivers eventually lead to the ocean, and so do the majority of the rock particles from mountains that travel downstream. Waves, tides, and other elements in the water continue to break down these pieces until they become the tiny little rock grains we call sand. Most of us envision beige sand on a beach, but it actually comes in a variety of colors. Tan, pink, white, and even black are all options. The color of the sand is determined by the type of rock from which it was extracted. Tan sand is the most common and is composed of a rock called quartz that has been tinted by a chemical called iron oxide and another mineral called feldspar. Iron oxide is a type of rust, which is why the sand has an orangey-reddish tan tint. Pink sand beaches are less common, but they can still be found in beautiful places around the world, including Bermuda, the Bahamas, Greece, the Philippines, and Indonesia. The pink color comes from minifera, which are tiny single-celled critters with red shells that tint the sand pinkish. Pink sand is found in tropical areas because these tiny organisms live in coral reefs. White sand beaches are mostly made of quartz, but the sand heads haven't been tinted by iron oxide for feldspar. Black beaches, which form near volcanoes, are probably the most uncommon. They are formed by eroding lava and basalt rocks produced by volcanic eruptions. Iceland, Hawaii, and Japan are just a few examples of places known for their volcanic black sand beaches. 

The rock particles do not adhere to one another, and this type of soil, sand, does not hold any water. Because sand is coarse and loose, water can easily drain through it. Sand is not a good soil for growing plants because it does not retain water or nutrients necessary for plant growth.

3. Silt

Silt contains medium-sized rock particles that are smaller than those found in sand. When wet, it has a smooth feel. In contrast to sand, which does not hold any water, clay does. Because silt does not drain as well as clay, a bird's footprint sticks to it. Silt is a type of soil that is primarily deposited by rivers. When a river flows down a mountain, it carries some weathered or broken rock particles with it. When the river reaches the lower areas, it deposits those fine particles on the river's banks and river beds. It appears to be very fine sand, which is soft to the touch.

4. Claying soil or clay.

It is composed of extremely fine particles that adhere to one another. It can hold a lot of water, but not much air. It is commonly found near river beds and is very soft and smooth to the touch. Clay has the smallest rock particles of any soil type, and it feels sticky when wet and hard when dry. The small rock particles packed tightly together hold the most water, but because there is little space for air, the water helps clay keep its shape. As a result, it is used in the production of pottery.

Clay particles adhere to one another very closely. It feels silky and smooth to the touch. Clay absorbs water and allows it to drain slowly. Clay doesn't drain well and doesn't provide space or air for plant roots to breathe. So, using only clay in the garden is not a good idea because it prevents plants from growing properly. Roses, Bergsmots, Compassplant, and Partridge Peas are grown in clay soil. Clay can be fired or sun-dried to make bricks, which are then used in building construction.

What is the best type of soil for growing plants?

Most plants cannot grow in sand because it does not hold enough water. Clay holds but does not contain the necessary air for plants. As a result, the best soil for growing plants is called loam, and it is composed of sand, silt, clay, and humus. 

Humus is composed of decomposing plants and animals.

5. The Loam.

Loam is a mixture of sand, silt, gravel and humus. It is made up of various rock particles and humus. It has an equivalent amount of all four. The quantity of different kinds of soil in loam soil determines its quality. It retains a good amount of moisture while also allowing for good drainage. The decaying plant and animal matter add structure to the soil, which helps keep plant roots in place.

Loamy soil contains a lot of air and water. It is widely regarded as the finest soil for growing plants and crops.

All crops do not grow in all soils; each plant requires a certain amount of water and air to grow properly, so various soils are appropriate for the growth of different types of plants. However, plants grow well when the soil can contain enough water, air, and humus. For example, rice requires a lot of water to grow, so it grows well in clay soil, whereas wheat grows well in loamy soil, and date palms grow well in sandy soil. Other factors that aid crop growth include the sun, water, air, and appropriate farmer care. All of this will be useless if the soil is not fertilized. The soil must be fertilized. Soil fertility refers to the soil's capacity to grow good and healthy crops. 

Loam is always a gardener's first choice because it contains humus and is a mixture of all types of soil. Hence, loamy soil is excellent for growing plants. Loam is frequently used in the cultivation of flowers, fruits, and vegetables.

Humus:

an organic material that is dark brown or black in color and is composed of decayed plant or animal matter. It is the remains of living material that become a component of the soil, like when small insects and animals die in the soil and their bodies decompose into humus. Plant waste such as fallen leaves, twigs, fruits, and seeds also decompose into humus, which makes the soil very fertile by adding nutrients and darkening its color. Because of the combination of soil and humus, loam is the best soil for growing plants because it has the ideal amount of air, water, and nutrients.

Soil and Plants.

Soil provides plants with the nutrients and water they require to develop. Aside from supplying food and water, plants absorb nutrients from their roots. Soil helps plants stand upright by holding their roots in position. When roots take hold in the soil, they prevent soil erosion. For example, tree roots prevent soil erosion by reaching deep into the soil and holding it together. Farmers want to plant their crops in the finest soil with the most nutrients to prepare the soil for seed planting. A tractor is used to till the ground with a cultivator. Soil tilling mixes up the topsoil, bringing nutrients to the surface. Crops grow in a variety of soil types. Rice grows in clay-rich soil that retains a lot of water. Pineapple grows best in sandy soil, while carrots grow best in a blend of soils. Top soil is a valuable natural resource because soil farmers strive to conserve it by rotating the types of crops they grow and controlling irrigation so that soil does not wash away when crops are harvested. The farmer allows the plants that were left behind to decompose and become part of the soil again, providing nutrients.

It is known that soil is fertilized by a herbal plant called Butterfly Pea Flower. This plant provides nitrogen to the soil. Butterfly Pea Flower - Clitoria ternatea

Soil and worms.

Worms spend their entire lives eating soil; they feed on decaying plants and leaves within the soil, which contributes to soil health. A worm does not have eyes, legs, or teeth when examined under a microscope, but it does have strong mouth muscles that allow it to swallow tiny bits of soil. Worms eat what is in front of them as they move forward and back. The soil passes through the digestive system of the worms and emerges as waste known as "castings", which are high in nutrients for plants. Worms contribute to soil in other ways as well. After it rains, worms crawl deep underground, creating tunnels. Worm tunnels are beneficial because they mix up the soil, allowing air and water to enter and helping plants grow. Farmers raise worms like other animals because they are so beneficial. Worm farms raise millions of wriggling earthworms, which are then sold to other farmers to keep their soil healthy. 

The soil is teeming with biodiversity.

Fungus and bacteria are among the other organisms found in the soil.

All of these organisms, including earthworms, contribute to the fertility of the soil. These organisms decompose the remains of dead plants and animals, converting them into simple substances. And these elements make the soil fertile.

Fungi

Fungi collaborate with plant roots as well. They grow in super thin-strands that extend from the roots of plants. In fact, they function similarly to extra roots, assisting the plant in extracting nutrients from the soil. The plant provides some of the food it produces, as well as other useful items, to the fungi. However, not all soil fungi and bacteria attach to roots. Some generate energy by breaking down dead plants and creatures. They are referred to as decomposers. Decomposers are essential because, without them, dead plants and animals would pile up. They are cleaning up the environment. Soil decomposers are an essential source of food for critters such as worms and tardigrades. After they are eaten, the waste critters generate acts as fertilizer, helping plants above the soil to remain healthy. 

Important Functions of Soil.

Soil is used in a variety of ways, including making animal and human habitats. People and animals rely on soil to grow plants for food, but soil has other uses as well. People all over the world build their homes out of soil. Wet sand and clay soil are poured into rectangular molds. Mud bricks, also known as adobe bricks, are stacked on top of one another to form a building's walls. 

Soil stores minerals.

Soil contains minerals that act as nutrients for plants. Organic and inorganic mineral matter can be found in soil. The weathering of rocks produces inorganic minerals. Examples include magnesium, sodium, potassium, iron, aluminum, sulfur, and chlorine. Organic minerals, on the other hand, are formed from the decomposition of plant and animal remains. Inorganic minerals provide calcium to plants, while organic minerals provide nitrogen, water provides hydrogen, and air provides carbon dioxide to plants. 

Soil stores water.

Soil is made up of particles and pores, which can be filled with air or water. The number of pores in soil varies according to soil type. Infiltration is the process by which water enters the soil; when the soil has taken up all of the water, it is said to be saturated. Water is purified by the soil. Rainwater filters and purifies itself as it passes through the various layers of soil. For all the waste water that passes through it, soil acts as a physical strainer, a biochemical renovator, and a biological recycler. 

Many different types of organisms live in soil. Both macro- and microorganisms live in soil. Worms, rodents, and insects are examples of macroorganisms. Microorganisms include fungi, bacteria, algae, protozoa etc. These macro- and microorganisms are crucial. Moles spend their lives underground, digging tunnels to search for worms and insects in the soil. Many animals live in burrows beneath the ground, such as the Kitfox, the burrowing owl, and the tiger salamander. 

Earthworms aerate the soil, creating air spaces in the soil. And it also aids in the disintegration and mixing of its constituents by passing large amounts of soil through their bodies and ejecting it on the surface as worm casts. The amount of soil that earthworms pass through their bodies is massive. Earthworms are thought to transport about ten tons of soil per acre per year. The soil ejected by earthworms is more fertile than the original. Earthworm activity causes soil to be transferred from the lower layers to the surface. The earthworms' small burrows provide aeration and drainage in the soil. 

Soil is the medium in which plants grow. It provides all of a plant's needs for growth. Water and some aerated nutrient solutions are two other mediums in which plants can grow. However, soil is the most common and important medium for plant growth. There are other mediums in which plants can grow besides water, and some aerated nutrient solutions are also possible. However, soil is by far the most common medium for plant growth.

Plant needs that are met by soil:

Mechanical support: 

Growing plants can stay upright because their roots are anchored in the soil. The soil's hold on plant roots causes plants to stand upright. 

Nutrient Supply: 

Roots penetrate deeper into the soil in search of nutrients, water, and air.

Air and Water Supply

Soil acts as a reservoir for both water and air. The plant absorbs water from this reservoir through its roots. Roots take in oxygen from the air stored in the soil. The heat or warmth of the soil aids in the rapid decomposition of litter. They allow nutrients to be released more quickly. 

The soil also stores the heat from the sun and distributes it to the growing plants. Soil is required for the production of many things, including nearly everything we use in our daily lives. All the fruits and vegetables we eat, as well as the clothes we wear, are supported by soil. The majority of the clothing we wear is made of cotton, which comes from cotton plants, which are grown in soil. Many baskets and carry bags are made of jute, which grows in soil. Erasers are made of rubber, which comes from a tree that grows in soil. Tea leaves are used to make tea, which is a plant that grows in soil. The milk we drink comes from a cow, and the grass this cow eats is a plant supported by soil. Hence, soil has numerous applications. 

Loamy soil mixed with straw is also used in wall construction and applied to the inside of walls to control humidity. 

Soil nourishes plant seeds, allowing them to germinate and grow healthy. It gives nutrients to plants, keeps their roots stable and strong beneath the soil, and aids in the absorption of water and minerals.

In the construction:

Since ancient times, soil and rocks have been used to construct various buildings. Many forts and locations have been built with sand, stone, marble, and soil. In fact, the bricks used to build modern houses are made of soil as well. 

In villages, houses are directly made of mud, and sandy soil is used to produce items such as glass and cement, both of which are useful during construction. Cob is made by combining clay, straw, and sand. And cob is a building material that is used to make buildings, ovens, and benches. Clay soil is also used in making walls, floors, counter tops, and ceramic tiles. Pottery can be made from clay soil. A lump of clay is hand-molded into cups, bowls, and vases. Some cultures paint their faces and bodies with natural colors found in soil. This allows people to express themselves as well as their community's traditions. 

Soil is also used in medicine; a naturally occurring bacteria in soil is used to create antibiotics that treat infections.

The soil is home to a variety of organisms in our ecosystem, including rabbits, ants, moles, scorpions, earthworms, and snakes. 

Finally, soil provides us with many essential minerals such as iron, copper, and aluminum.

It can be shown below.

• Iron ore -> iron 
• Copper ore -> copper 
• Aluminium ore -> Aluminium
