What are the major horizons of soil?

Most soils have three major horizons — the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation).

What are the 6 ecological functions of soil?

These six ecological roles are providing a medium for plant growth, supplying a recycling system for organic wastes and nutrients, modifying the atmosphere, providing a habitat for soil organisms, offering a system for water supply and purification, and providing an engineering medium.

What is the top layer of soil called?

topsoil layerThe layers of the soil are called horizons. The uppermost horizon is called the topsoil layer. The topsoil layer is a mixture of sand, silt, clay and broken down organic matter, called humus. Humus is rich, highly decomposed organic matter mostly made from dead plants, crunched-up leaves, dead insects and twigs.

What are the three main characteristics of 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. Soil is made up of different-sized particles. Sand particles tend to be the biggest.
