In Northern forest soil, Humus is present above topsoil.
Humus is a black/brown substance that is formed by the decay of plant and animal matter.
Above the topsoil in a northern forest soil, you would typically find a layer of organic material called the forest floor. This layer forms as dead leaves, twigs, and other organic matter decompose over time. The forest floor helps to replenish nutrients in the soil and provides habitat for small organisms.

Above the topsoil is the subsoil, which consists of a mixture of clay, minerals, and organic matter. This layer forms as water carries minerals and nutrients down from the topsoil, depositing them in the subsoil layer. This process usually takes hundreds to thousands of years.
The plural form is topsoils, a word for different types of topsoil.

There is no guarantee that it will ever recover. The layer of topsoil in a rainforest is extremely thin. Because there is so much competition for food in the forest, little material builds up to form topsoil. When the trees are cut down and the thin layer of topsoil is exposed to sun, wind, and water, it is more susceptible to erosion. When the topsoil disappears, the land becomes un-arable, and becomes essentially desert.

Topsoil loss is considered a worldwide problem because topsoil is crucial for agriculture and food production. It takes centuries to form a few centimeters of topsoil, and erosion rates are much higher than the rate of topsoil formation. Without fertile topsoil, it becomes difficult to grow crops and sustainably support the growing global population.
