Which type of soil is more fertile?
Alluvial soil
Alluvial soil is the most fertile soil because it has loamy texture and is rich in humus. It has good water absorbing capacity and water retention capacity.
How is soil made more fertile?
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose …
Which soil type has higher fertility and organic matter?
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.
Where is the most fertile soil?
Found in Ukraine, parts of Russia and the USA, mollisols are some of the world’s most fertile soil. This type of soil includes black soils with high organic content. Vertisols – 2.5% of the world’s ice-free land.
Which is most fertile soil in India?
Alluvial soil is the most fertile soil in India. Alluvial soils is are formed by the deposits of the sediments brought by rivers. Most of the rivers originate from the Himalayas and bring along high amount of sediments with them. The soil is made up of particles like silt, sand and clay.
Which soil is one of the most fertile soil of the world?
Mollisols in particular are outlined by some sources as being the most fertile, most productive and most economically valuable soil in the world. Alfisols also have high natural fertility, and can be productive for a range of uses.
What place has the most fertile soil?
Where is soil most fertile?
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.
Which is soil do you think would produce a more fertile soil?
Originally Answered: Which soil do you think would produce a more fertile soil, those derived from igneous rocks or those that are derived from metaphoric rocks? Why? the best soil are made on limestone mother rock because it give calcareous and clay which is needed to make humic argilo complex.
What can I put in my soil to make it more fertile?
Compost is a mixture of organic residue such as manure and straw that have been piled, mixed, and moistened to undergo thermophilic decomposition. Compost helps to improve fertility, bulk density, and water-retention properties of soil. Also, unlike raw manure, compost does not introduce weed seeds to your farm.
Remember, soil fertility is only one component of soil quality. Fertile soils are able to provide the nutrients required for plant growth. These are the chemical components of soil. Some plants need certain nutrients in large amounts, like nitrogen, phosphorus, and potassium, which are called macronutrients.
How does organic matter affect the fertility of soil?
Organic matter prevents tiny particles of clay from cementing themselves into a solid mass. This enables plant roots to move easily throughout the soil. It increases the cation exchange capacity or C.E.C., which is a measurement of a soil’s ability to hold nutrients.
