What is soil farming? what is the importance of soil in agriculture.

Soil is loose material which lies on top of the land. It has many things in it, like tiny grains of rock, minerals, water and air. Soil also has living things and dead things in it: “organic matter”. Soil is important for life on Earth. Because soil holds water and nutrients, it is an ideal place for plants to grow.
Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties.
The top layer of the earth’s surface in which plants can grow, consisting of rock and mineral particles mixed with decayed organic matter and having the capability of retaining water. …
Soil can be classified into three primary types based on its texture – sand, silt and clay. However, the percentage of these can vary, resulting in more compound types of soil such as loamy sand, sandy clay, silty clay, etc.

Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Different Types of Soil – Sand, Silt, Clay and Loam.
- Sandy soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. …
- Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients. …
- Silt Soil. Silt Soil is a light and moisture retentive soil type with a high fertility rating. …
- Peat Soil. …
- Chalk Soil. …
- Loam Soil.
All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil’s properties – its texture, structure, porosity, chemistry and colour.
Silt, clay and sand are the three main types of soil. Loam is actually a soil mixture with a high clay content, and humus is organic matter present in soil (particularly in the top organic “O” layer), but neither are a main type of soil.
Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. It forms at the surface of land – it is the “skin of the earth.” Soil is capable of supporting plant life and is vital to life on earth.
Why is soil important? Healthy soils are essential for healthy plant growth, human nutrition, and water filtration. … Soil helps to regulate the Earth’s climate and stores more carbon than all of the world’s forests combined. Healthy soils are fundamental to our survival.
- Clay Soil. Clay soil feels lumpy and is sticky when wet and rock hard when dry. …
- Sandy Soil. …
- Silty Soil. …
- Peaty Soil. …
- Chalky Soil. …
- Loamy Soil.
- Sandy Soil. Sandy soil is light, warm, and dry with a low nutrient count. …
- Clay Soil. Clay weighs more than sand, making it a heavy soil that benefits from high nutrients. …
- Peat Soil. Peat soil is very rarely found in natural gardens. …
- Silt Soil. …
- Loamy Soil.
Soil provides many services and many products. The plants that are grown in soil can be used for food, clothing, recreation, aesthetics, building materials, medicines, and more. The minerals that make up soil particles can be used for dyes, make-ups, and medicines, or shaped into bricks, plates, and vases.
