- Texture is a measure of whether the soil is more like sand, silt, or clay. The more like sand a soil is the less water it can hold. On the other hand, the more like clay a soil is, the more water it can hold. Soil Horizons Soil is made up of many layers. These layers are often called horizons.

Feb 17, 2023 · Soil Horizons. The soil is the topmost layer of the earth’s crust consisting of air, water, inorganic minerals (rock, sand, clay, and slit), and organic matter (dead plants and animals). It forms the source of food for plants.
Soil is often described using several characteristics including texture, structure, density, temperature, color, consistency, and porosity. One of the most important properties of soil is the texture. Texture is a measure of whether the soil is more like sand, silt, or clay.
Most soils have three major horizons (A, B, C) and some have an organic horizon (O). The horizons are: O (humus or organic): Mostly organic matter such as decomposing leaves. The O horizon is thin in some soils, thick in others, and not present at all in others.
Sep 21, 2019 · Soil Texture. When you pick up a handful of soil, you can feel how coarse or fine it is. In other words, you can feel its texture. Soil mainly contains particles of sand, silt and clay. The ratio between these particles determines soil texture. Loam is soil that has equal parts sand, silt and clay.
The soil is the topmost layer of the earth’s crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons. Also Read: Soil Teeming.

What are the characteristics of soil?
Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness. Other properties are less visible. Properties, such as chemical and mineral content, consistence, and reaction require special laboratory tests.
