Soil has varied functions beneficial for plants, trees, animals and humans. In addition to its many roles, soil supplies nutrition, support, protection, and filtration. Gardeners help to nourish and safeguard the soil ecosystem by planting in the ground. As a result, this ecosystem helps to support our world, emphasizing the necessity of soil in any garden. Human life would be extremely difficult without soil. It gives plants a place to put their roots down and also contains the nutrients required for plant growth. Furthermore, soil filters rainfall and manages surplus precipitation, preventing flooding. It can also store huge amounts of organic carbon, act as a pollutant buffer, and safeguard groundwater quality.

The soil protects root systems from temperature fluctuations. Roots can be protected from heat and cold by the density of the soil and air pockets in the soil particles. The carbon cycle is kept in check by the numerous processes that take place in the soil. It acts as a filter to prevent dangerous pollutants and chemicals from rain or the surface soil. Water cannot rush through the rocks because of the soil particles. The soil's sponge-like qualities hold water for use by plants and trees, as well as soil microorganisms and other soil dwellers.

Soil and plants

Soil helps various kinds of plants in a variety of ways. Soil is nature's nurturer, providing water, nutrients, and anchoring plants and trees. Soil provides support for root systems. It acts as an anchor for the plant or tree, allowing it to stay vertical. Plants of all kinds rely on the soil for nutrients and minerals to develop, produce blooms, seeds, and, in some circumstances, fruits and vegetables. The type and quantity of these critical and sustaining elements are determined by the type of soil. In soil, oxygen is trapped in the gaps between the particles. This supplies oxygen to the roots of plants and trees. Plants and trees rely on the soil for protection against erosion and being swept away during strong rainstorms. Soil provides the necessary support for root systems to prevent plants and trees from being uprooted by severe windstorms and other types of weather. Unwanted and hazardous chemicals can be filtered out of the soil and away from the roots of plants and trees. Soil has the ability to hold water, allowing plant root systems to have constant hydration and nutrients. The amount of water that a soil can hold is determined by the type of soil.

Soil and humans

Humans, like the rest of the animal and plant kingdoms, highly rely upon soil for a variety of purposes. We mainly depend on soil to grow the plants for food, specifically the type and quality of soil. Plants that grow in nutrient-rich soil, such as compost, can provide an abundance of healthy vegetables and fruits for humans to eat. Soil serves as a base for a variety of human construction endeavors, including dwellings and buildings. Roads, railways, and bridges are all built on top of soil. Humans employ soil's raw elements, such as nutrients, microorganisms, and minerals, to grow food, depending on the type and quality of the soil. Different soils and sediments were used to make ancient pottery. Modern pottery and ceramics are still made from clay soils. For ages, adobe bricks have been employed. Clay is used to make modern bricks, which are then burnt in a kiln.

Soil and animals

Animals, whether directly or indirectly, rely on the soil for food. Burrowing animals rely on the soil to offer dwellings and safety, while grazing animals rely on the soil to generate grasses. The diversity of animals is determined by the quality of the soil. The survival of the insect population is likewise dependent on soil. The soil impacts the chances of survival for pollinators, ants, and other underground organisms.
