The soil horizon that has the darkest and richest soil is usually the topsoil layer, known as the A horizon. This layer contains a high amount of organic matter and nutrients, making it ideal for plant growth.
The darkest layer of soil, rich in organic matter, is called the topsoil or the A-horizon. This layer is crucial for plant growth as it contains nutrients and microbial activity necessary for healthy soil fertility and plant development.
The horizons of a soil profile are O horizon (organic matter), A horizon (topsoil with organic material), E horizon (zone of leaching), B horizon (subsoil with accumulation of minerals), C horizon (weathered parent material), and R horizon (bedrock).
The O horizon, also known as the organic horizon, contains the most organic matter in soils. This layer consists of decomposed plant materials like leaves, branches, and other organic debris that have not yet fully broken down.
Materials leached from horizon A are typically deposited in the B horizon of the soil profile. As water moves through the soil, it carries minerals and nutrients from horizon A and deposits them in the B horizon.
The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.

No fertile is the richest soil.
THe c horizon
Soil layers are called soil horizons. Typically, a soil includes an A horizon, a B horizon and a C horizon. In laymen's terms: A horizon = topsoil B horizon = subsoil C horizon = parent material (the stuff in which the soil formed)
The Southern Colonist had the richest soil.

soil horizons determine the age of the soil
its called a horizon horizon
Materials leached from horizon A are typically deposited in the B horizon of the soil profile. As water moves through the soil, it carries minerals and nutrients from horizon A and deposits them in the B horizon.
horizon A , horizon B and horizon C
The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.
