How does soil affect forests?

Soil is critical to forest development and maintenance. It offers moisture and nutrients for tree development, acts as a medium for root growth, and physically supports harvesting, yarding, and other operations equipment. Soil productivity is crucial to long-term forest management. The more productive the soil, the less likely it will be that trees will have to be removed for agricultural purposes.

The type of soil influences the kind of forest that can grow there. For example, dry soils typically lead to tree species that are well adapted to these conditions. Forests like this one in California's San Bernardino National Forest are called desert scrub forests because they consist mainly of small shrubs with spines or thorns to protect them from animals (especially humans!), dry weather, and limited water sources. Trees in deserts scrub forests do not grow very large because they don't need to attract attention from predators or compete for sunlight with other plants. Their tough, spiny leaves and small fruit help them survive drought and heat waves.

Forests on wet soils tend to be more diverse. They may include trees from several different families, such as the examples shown here in Oregon's Willamette National Forest. These forests are known as broadleaf forests because most members of their communities have broad leaves. Broadleafs are more efficient use of energy than spines, so they outnumber trees with sharp needles in this type of forest.

How good is forest soil?

Because of the decaying leaves near the soil surface, deciduous forest soils are particularly rich and productive agricultural fields. Forests are vital because they store a significant amount of carbon in their leaves, trees, and soil, which is why they must be protected.

Soil in forests is often very deep because it has been weathered down over time or washed away by rain. The soil in a forest may be composed of small, hard particles that stick to each other (like sand) or soft particles that lie flat when you walk on them (like silt). The type of tree that grows in a particular area affects how much soil there is, where it is found, and what kind of material it is. For example, trees such as black cherry, beech, and sycamore produce large amounts of fruit that drop off the branches into the ground, providing nutrients for future generations of trees. Scientists have used these kinds of trees to create models of how much carbon is released back into the atmosphere when they die. They find that depending on the species, some release more than others do. Trees that don't drop their fruit but rather spread their seeds out over a wide area using their roots (such as red maple) also play an important role in fertilizing their habitat.

Most forests around the world are located in cold climates with relatively short growing seasons.

What is forest soil?

Forest soils, where forest vegetation has affected soil formation, are often distinguished by firmly rooted trees, substantial "litter layers" or O horizons, recycling of organic materials and nutrients, including wood, and a diverse range of soil-dwelling animals (Figure 1). Agricultural soils, in contrast, are usually characterized by the absence of large trees, little litter, few or no organic matter reserves, and few animals. Agricultural soils may be improved by management practices that increase carbon storage in soil organic matter or by planting species that promote biological soil improvement strategies such as cover crops and green manures.

Soil provides food, shelter, and other resources for plants. Healthy forests also provide many other benefits to humans, from reducing greenhouse gas emissions to providing beauty and recreation. Protecting forests helps protect these benefits that we receive from them every day.

Forests play an important role in removing pollutants from the air we breathe. They use the same processes that we do - breathing in oxygen and breathing out carbon dioxide - but they do so at a much faster rate. The leaves and branches of trees absorb both sunlight and air pollution gases like sulfur dioxides and nitrogen oxides. The trees' roots go deep into the earth, reaching down past all those years worth of dead trees and limbs, and they take up these chemicals into their bodies where they can be stored for future use.

What is vegetation and soil?

As a result, plant and soil are inextricably linked and have mutually beneficial impacts on one another. At many geographical scales, vegetation provides vital processes in an ecosystem. Soil is essential in nature because it provides nutrients for plant growth as well as home for millions of micro- and macroorganisms. The soil organism community plays a crucial role in the cycling of elements such as nitrogen, phosphorus, and potassium. It also affects the water quality by breaking down debris from plants and animals and filtering out harmful substances.

In return, vegetation benefits from soil by absorbing moisture from the atmosphere and reducing erosion due to wind or water. Plants use the water they need to grow through their roots, and then release it back into the air when they transpire. This is why moist areas within forests often have more plants than dry ones - they're able to absorb more water this way. On the other hand, if there's too much water, it can cause soil to become saturated, which can lead to flooding or mudslides. Vegetation also helps control temperature by growing heat-retaining trees in warmer climates or cold-reflecting ones in colder ones. Finally, plants provide food and shelter for many species of animals, including humans.

Soil has a huge impact on the Earth's environment, but human activity has had an even greater influence over the last 100 years.
