What is the soil question answer? ›

Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides structural support to plants used in agriculture and is also their source of water and nutrients.

Preparation of soil: Preparation of the soil involves loosening and turning the soil. This process is known as ploughing, is done by using a wooden or iron plough which pulls the soil. The pulled soil is then levelled by using a wooden or iron leveller.

Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and sand (Figure 1); the percentages of particles in these size classes is called soil texture.

Types Of Soil - Sandy Soil, Clay Soil, Silt Soil, And Loamy Soil.

Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms.

Plants that grow in the soil can be used for medicines, clothing, building materials, etc. Soil provides anchorage for roots and holds water and nutrients. Nutrients are recycled in the soil. Soil is a natural medium for filtering and purifying water.

Pedology: This is the correct answer. The scientific study of soils as natural phenomena, including their composition, distribution, and formation processes, is known as pedology.

soil - (i) The unconsolidated mineral or organic material on the immediate surface of the Earth that serves as a natural medium for the growth of land plants.

Soil is formed by the process of weathering wherein rocks break down by the combined action of wind, water and climate. It is a very slow process where over a period of time large rocks disintegrate and then get converted into soil.

If it holds its shape but crumbles when you give it a light poke, it is loamy soil. This is the best soil for plants. If it holds its shape and doesn't respond to being gently poked, then it is clay soil, which is nutrient rich but dense. If it falls apart as soon as you open your hand, it is sandy 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.

Generally speaking, clay-rich soils have the largest pore space, hence the greatest total water holding capacity.

Soil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support for plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties.

It is the unique blend of each that gives it it's characteristic, determining which soil type it is and which are better for growing plants and crops in. There are three main categories of soil: sandy, clay or loam.

The four fundamental soil types are sandy soil, silt soil, clay soil, and loamy soil. Clay soil: Clays are chemically active as a result, and they may contain nutrients on their surfaces. These nutrients can be released into the soil water, where they can be used by plants.

Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.

soil - (i) The unconsolidated mineral or organic material on the immediate surface of the Earth that serves as a natural medium for the growth of land plants.

Soil is mineral and/or organic material at the Earth's surface that is capable of supporting plant growth and that is influenced by the soil forming factors of climate, vegetation, parent materials, topography and time.
