What are the 4 main layers of soil?
Soils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base (Figure 31.2. 2). The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base.

Why is the topsoil considered 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.

Where is the most fertile soil in the world?
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. This type of soil is found in India, Australia, sub-Saharan Africa, and South America.
Which part of soil is fertile?
SOIL FERTILITY. Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel).
