Learning about uses of soil is highly crucial for kids to know about its agricultural, ecological and environmental significance. Soil is like the skin of earth which is home to countless living organisms and plants. From sustaining life to regulating earth’s temperature, soil plays a crucial role in sustaining life on earth. Let’s explore some most fascinating facts and uses of soil in our lives.

What is Soil

Soil is the mix of minerals and organic matter that holds air, water and microorganisms. It is a thin powerful layer that covers most of the land and supports the ecosystem in many ways. There are four main components of soil: mineral particles, organic matter, water and air. Each of these components work together to create a remarkable ecosystem.

Significance and Uses of Soil

Soil serves as the fundamental foundation for life on earth. From agricultural to environmental significance, soil is a life-support system for us in many ways:

Biodiversity: Soil is the reservoir for biodiversity on earth. It is home for a vast variety of living organisms such as bacteria, fungi, insects, earthworms, moles and burrowing mammals. The diverse microbial life living in soil is a great contributor in the ecosystem. It helps in cycling nutrients, decomposing organic matter, purifying water and in formation of soil structure.

Food Production: Soil has a huge agricultural significance. It is the foundation for growing all types of food on earth including grains, vegetables, fruits and crops. From anchoring roots to providing all the vital nutrients soil gives the necessary support a plant needs to grow. The properties and right type of soil for agriculture is important. For example, clay soil is considered the most suitable type of soil for framing as it retains water and nutrients for proper growth of crops.

Climate Regulation: Soil acts as a huge terrestrial store for the carbon present on earth holding much more carbon than both plants and trees on the earth. After the plants or animals die their bodies are decomposed by microorganisms in the soil This carbon from their remains stays in the soil before returning to the atmosphere. Sometimes this carbon stays in the soil for hundreds for years before getting released into the atmosphere. This stored carbon in soil plays a crucial role in regulating earth’s climate. The soils store around 1,500 billion tonnes of carbon which is much more than the carbon present in the atmosphere and is vital for our planet.

Water Filteration: One of the remarkable functions of soil is purification of water. Soil filters the rian water and stores it as groundwater which we extract and consume. The different layers of soil act as a giant filtration system that cleans the water and stores it. The microorganisms living in the soil filter out pollutants and contaminations in water before sending it to the underground sources called aquifers. Healthy soil seeps water like a sponge and reduces the chances of flooding

Properties of Soil

Certain properties determine the uses of soil and dictate its fertility, health and ability to grow plants. The physical, chemical and biological properties of soil are described below:

Physical properties of Soil determine how it holds water, air and root growth. The physical properties of a soil include soil texture, soil colour, soil structure, etc.
Chemical properties of soil tells its nutritional value of the soil and the chemical process happening inside them. Various factors such as soil pH, sodium absorption ratio, etc are known as its chemical properties.
Biological properties of soil refer to the living components of the soil such as bacteria, fungi, arthropods and earthworms.

Different Types of Soil

The type of soil matters to decide the type of plantation that grows in it. Based on the properties of soil it can be categorized into following types

Sandy Soil: Highly concentrated sandy particles, sandy soil is grainy with a lower amount of nutrients. This type of soil warms quickly and becomes dry as it has low water retention that supports medium plant growth. Plants that need well-draining soil and hot weather grown in this soil such as olives, rosemary and oregano.

Clay Soil: This type of smooth soil has a huge agricultural significance. It is highly moist with high nutritional composition that is suitable for growth of crops. The particles in clay are closely packed and lock the roots to limit their airflow which help them to grow better.

Peaty Soil: With higher composition of decomposed organic matter, peaty soil is extremely fertile and full of nutrients. Its spongy texture makes it suitable for retaining water and is suitable for growing vegetables, shrubs, trees and grass. This kind of soil often needs drainage for keeping plants healthy.

Chalky Soil: This type of soil contains rocks or limestone particles and is commonly found in higher altitudes. It has a low pH level and needs manure or fertilizers to grow plants. Trees, shrubs and vegetables like cabbage, spinach and beets can grow in chalky soil.

Loamy Soil: Clay, stilt and sand together form loamy soil which is rich dark soil which is nutrient dense and perfect for growing plants, vegetables and trees. It can retain moisture and has excellent drainage capabilities that give suitable conditions for the plants to bloom.
