Since man has inhabited the earth the soil has been the medium in which to grow and produce food for himself and his animals. Importance (Functions) of soils Soils are essential for life, in the sense that they provide the medium for plant growth, habitat for many insects and other organisms, act as a filtration system for surface water, carbon store and maintenance of atmospheric gases. Let us … The color of the soil is another way to characterize soil. Here are five reasons to treasure our often overlooked natural resource. Soil has vital nutrients for plants. Healthy soils are the foundation of the food system. This soil is very fertile and is ideal for planting and farming. Organisms found in the soil, such as worms, beetles, bacteria and fungi, obtain food from the soil. The following are importance of soil: Soil is the medium in which most of the plant grow and thus soil is used to grow crops; Soil forms the foundation of … Healthy soils produce healthy crops that in turn nourish people and animals. Underscoring its importance, 2015, the year in which the world community will agree a new global development framework to succeed the Millennium Development Goals (MDGs), has been declared the International Year of Soils by the United Nations. Soil is regarded as life and the pillar of agriculture because it is the medium onto which most plants grow. Soil is one of the three principal natural resources; the other two are air and water. Soil distribution can impact rivers, lakes and streams, … The soil is one of the most valuable natural resources available to us.

The importance of soil and its uses include.

Without fertile soil we would have no plants. Indeed, soil quality is directly linked to food quality and quantity. Soil that has a light gray or white tint has a lot of calcium or silica. Six key soil functions are: Food and other biomass production Environmental Interaction: storage, filtering, and transformation Biological habitat and gene pool Source of raw materials Physical and cultural heritage Platform for man-made structures: buildings, highways I’m study geography, the reason is: (1).

(2). A shallow accumulation of lime in low rainfall areas as caliche Formation of acid soils in humid areas Erosion of soils on steep hillsides Deposition of eroded materials downstream Very intense chemical weathering, leaching, and erosion in warm and humid regions where soil does not freeze Soil is an important part of the building process.

Soil is important in providing an adequate water supply and maintaining its quality. As a result, it is used in agriculture to nourish plants. 5 Uses of Soil Agriculture. Because a plants is absorb water from soil via the roots, therefore if no water in soil, the plant should be died. Soil that is black or a rich, deep brown is high in organic content.

The roots of... Building. Soil organism, any organism inhabiting the soil during part or all of its life. Soils serve as the only medium for plant growth. Without plants we would have no food. Earth's body of soil, called the pedosphere, has four important functions: . Our soils are the basis for agriculture and the medium in which nearly all food-producing plants grow. Yellow, red, or orange soil indicates that it is rich in iron. Some of the soil properties affecting plant growth include: soil texture (coarse of fine), aggregate size, porosity, aeration (permeability), and water holding capacity. The nutrients in the soil are rich. And without food, there is no us, since we need food to survive. The Role of Soil in our Environment . Soil and the vegetation it supports catch and distribute rainwater and play a key role in the water cycle and supply. Fertility to plants and crops; Microbial environment; Source of medicines; Retains water (enhances groundwater levels) Shelter for animals; Source of valuable minerals; Helps to decompose waste; Growth of microbes; Construction material

Soil organisms, which range in size from microscopic cells that digest decaying organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil.
