What are some interesting facts about soil?
Soil is a living system. A single gram of healthy soil contains millions of organisms including earthworms, nematodes, mites, insects, fungi, bacteria and actinomycetes. Soil is a frontier for exploration: Only about 1 percent of soil micro-organisms have been identified.
What 3 things make up topsoil?
The topsoil layer is a mixture of sand, silt, clay and broken down organic matter, called humus.
What makes topsoil so important?
The world grows 95% of its food in the uppermost layer of soil, making topsoil one of the most important components of our food system. Without topsoil, the earth’s ability to filter water, absorb carbon, and feed people plunges. Not only that, but the food we do grow will probably be lower in vital nutrients.
Does the soil die?
Soil can die. As soil is alive, soil can also die. And we humans have been killing a lot of soil. The short-term gains of conventional agricultural practices—like excessive tilling and application of chemical pesticides and fertilizers—eventually give way to reveal the long-term damage they do to soil ecosystems.
What is a bad thing about the soil?
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
What is the lowest of the soil layers?

The subsoil is a zone of accumulation since most of the materials leached from the topsoil accumulate here. The “C” horizon is the lowest layer. This is a transition area between soil and parent material.

Why is Topsoil is darker than subsoil soil?
Composed of a mixture of sand, clay, silt and a variety of other elements, including water and air, topsoil is full of nutrients and minerals that are essential to plant growth. Due to its extremely high concentration of microorganisms and decaying organic matter, topsoil usually is darker than subsoil, which is the soil below topsoil.

How do you make good soil?
First, you should aim to create good basic soil in your garden. Good soil is a mixture of clay (to retain water), sand (to drain water), and organic material (for nutrients). Soil that’s too heavy with clay won’t allow water to drain from plants, which can cause the roots to rot.
