Topsoil is found in the uppermost layer of soil, typically the top 2-8 inches. It is rich in organic matter, nutrients, and microorganisms, making it crucial for plant growth and agriculture.
The layer of soil is called the topsoil, which is the uppermost layer of soil that contains most of the organic matter and nutrients that plants need to grow. It is typically the darkest and richest layer of soil, where most plant roots are found.
The third layer of soil is the subsoil. It is found beneath the topsoil and consists of weathered rock fragments and minerals. It is generally less fertile than the topsoil but still plays a crucial role in supporting plant growth.
The topsoil is the finest soil layer. Soil 'layers' are called horizons.
The top layer of soil is called the topsoil. It is the outermost layer that contains the highest concentration of organic matter and nutrients, making it ideal for supporting plant growth.
