What is the topsoil made of?

The 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.

Hereof, what is the use of topsoil?

Topsoil is the top layer of the earth's surface. Topsoil is dark in color and high in organic matter, which makes it very easy to till and fertilize ground for growing plants. It is scraped from the ground and sold in bags or bulk, often called "black dirt".

What does it mean to screen topsoil?

Our screened topsoil is processed by passing natural 'As dug' topsoil over modern screening equipment to remove all large stones and other deleterious materials, such as plant roots, leaves and clay depending on the source. Our general purpose screened topsoil is designed to be used in all areas of the garden.

How topsoil is formed?

Chemical weathering also continues, turning the rock pieces into the sand, silt, and clay particles that make up our soil. Other soils formed in materials that were already physically weathered and deposited by moving water or wind, allowing topsoil to form much faster.
