Which type of soil is the most fertile and why?
Considered the most fertile of soil type, loamy soils are a combination of sandy, clay and silt particles. The clay and silt particles improve moisture retention while the sand minimizes compaction and improves drainage. Loamy soils don't get dried out in the summer, but also don't get water-logged in winter.
Which soil origin has the most fertile soil?
Alluvial soils are formed mainly due to silt deposited by Indo-Gangetic-Brahmaputra rivers. They are the largest soil group covering about 15 lakh sq km or about 6 percent of the total area. They support more than 40% of India's population by providing the most productive agricultural lands.
Where is the most fertile soil?
Fertile soil is usually found in river basins or in places where glaciers deposited minerals during the last Ice Age. Valleys and plains are usually more fertile than mountains.
What is fertile soil called?
Clue. Answer. Fertile soil (4) LOAM.
Which soil layer is the most fertile?
Topsoil is the upper layer of soil, usually between 2 to 8 inches in depth, that contains most of the ground's nutrients and fertility.
What are examples of fertile soil?
Examples may be: pineapples can be grown on marginal, sandy soils, while bananas need rich soils; damp and heavy soils are suitable for cocoa, yams or rice, but not for growing pepper etc. Soil depth: the exploitable volume for plant roots. Availability of water: moisture retention for continuous water supply.
Which layer of the soil is the most fertile?
Topsoil Topsoil is the upper layer of soil, usually between 2 to 8 inches in depth, that contains most of the ground's nutrients and fertility.
What soil is loamy?
A loamy soil, then, is one that combines all three of these types of particles in relatively equal amounts. Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots.
Why top soil is most fertile?
Topsoil consists of most weathered mineral and organic material. Biological agents are also responsible for the breakdown of complex organic matter which releases simple nutrients. This process of mineralisation make soil fertile.
Which part of the soil is fertile?
Usually a fertile soil will also have some organic matter that improves soil structure, soil moisture retention, and also nutrient retention, and a pH between 6 and 7….Nutrient Deficiencies.

Which layer of soil is very fertile and good for growing crops?
(a) A-Horizon (Topsoil): The topmost layer of the soil (also known as topsoil) that is very soft, porous and dark in colour is called A-Horizon. It has good water-retention capacity and roots of many plants absorb water from this layer. This layer contains a lot of humus that is required to make the soil fertile.
What is clayey soil?
: a soil that contains a high percentage of fine particles and colloidal substance and becomes sticky when wet.
What soil is sandy?
Sandy soils are those that are generally coarse textured until 50 cm depth and consequently retain few nutrients and have a low water holding capacity. Soil management practices which lead to an increase in the fine fraction are helpful in improving soil properties and crop productivity.
Which layer of soil is considered the most fertile?
A- Horizon Or Top soil is called the most fertile layer of soil because of the presence of humus which comprises of the organic matter along with minerals which help in the growth of various plants. Hence top soil Or A-Horizon is the most fertile layer of soil.
What is rich fertile soil called?

What is alluvial soil?
February 17, 2020 – Alluvial soils are soils deposited by surface water. You'll find them along rivers, in floodplains and deltas, stream terraces, and areas called alluvial fans.
What type of soil is clay?
Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients. Clay soils remain wet and cold in winter and dry out in summer. These soils are made of over 25 percent clay, and because of the spaces found between clay particles, clay soils hold a high amount of water.
Which layer of the soil is the most fertile Brainly?
The surface soil, or topsoil layer (O and A horizon in Figure 1–2), usually contains less clay, but more organic matter and air, than the lower soil layers. Topsoil is usually more fertile than the other layers and has the greatest concentration of plant roots.
What is fertility of the soil answer?
Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact.
Why is topsoil the most fertile layer of soil?
Topsoil consists of most weathered mineral and organic material. Biological agents are also responsible for the breakdown of complex organic matter which releases simple nutrients. This process of mineralisation make soil fertile.
What type of soil is best for growing plants Why?
Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots. Many gardeners complain of their garden soil being compacted and/or poorly drained.
Which layer of soil is considered the most fertile and productive for plants crops?
The surface soil, or topsoil layer (O and A horizon in Figure 1–2), usually contains less clay, but more organic matter and air, than the lower soil layers. Topsoil is usually more fertile than the other layers and has the greatest concentration of plant roots.
What is the best type of soil?
Best Soil For Plants: The ideal blend of soil for plant growth is called loam. Often referred to as topsoil or black dirt by landscape companies, loam is a mixture of sand, clay, and silt.
Why is loam soil the best?
Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots. Many gardeners complain of their garden soil being compacted and/or poorly drained. Heavy, compacted soil can be rescued by the enduring gardener.
Where are the most fertile soils found?
Fertile soil is usually found in river basins or in places where glaciers deposited minerals during the last Ice Age. Valleys and plains are usually more fertile than mountains. The Pampas, for example, is an extremely fertile plains region in South America.
Which type of soil is best for growing crops?
Loamy soil Loamy soil is the mixture of sandy soil, clayey soil and silt. Silt is the deposit in river beds. Loamy soil has right water holding capacity and is well aerated. This is considered as the best soil for the growth of plants.
Which type of soil is good for farming?
Loamy-textured soils Loamy-textured soils are commonly described as medium textured with functionally-equal contributions of sand, silt, and clay. These medium-textured soils are often considered ideal for agriculture as they are easily cultivated by farmers and can be highly productive for crop growth.
Why loam is a fertile soil?
Loam soil is a balanced mixture of sand, silt and clay, ideal for growing garden plants. Loam's mineral content, and the way the three sizes of particles work together, combine to make it extremely fertile. The larger sand grains prevent the soil from compacting, so it drains well and helps oxygen reach plant roots.
