As a result, it is used in agriculture to nourish plants. Some of the soil properties affecting plant growth include: soil texture (coarse of fine), aggregate size, porosity, aeration (permeability), and water holding capacity.

Without fertile soil we would have no plants. Our soils are the basis for agriculture and the medium in which nearly all food-producing plants grow. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. 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. Soil has vital nutrients for plants. Soil and the vegetation it supports catch and distribute rainwater and play a key role in the water cycle and supply. The Role of Soil in our Environment . 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. Plants are the basis of life because they are... Filtration system for surface water. Yellow, red, or orange soil indicates that it is rich in iron. Soils serve as the only medium for plant growth. Importance of Soil Medium for plant growth.

Here are five reasons to treasure our often overlooked natural resource. The color of the soil is another way to characterize soil. Soil is one of the three principal natural resources; the other two are air and water. Soil that is black or a rich, deep brown is high in organic content. 1. 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. Because a plants is absorb water from soil via the roots, therefore if no water in soil, the plant should be died. 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. 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 is important in providing an adequate water supply and maintaining its quality. Healthy soils produce healthy crops that in turn nourish people and animals. Soil is regarded as life and the pillar of agriculture because it is the medium onto which most plants grow. (2). Organisms found in the soil, such as worms, beetles, bacteria and fungi, obtain food from the soil. So, soil fertility is important. Since man has inhabited the earth the soil has been the medium in which to grow and produce food for himself and his animals. This soil is very fertile and is ideal for planting and farming. And without food, there is no us, since we need food to survive. Water Provision When moisture falls on the land – either from rain, snow, frost and mist, or from irrigation techniques – the soil absorbs and stores it. Without plants we would have no food. 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 Thursday, February 09, 2012 .

Soil compaction, which increases the density of the soil,... Pottery. I’m study geography, the reason is: (1). Soil is an important part of the building process. Earth's body of soil, called the pedosphere, has four important functions: . Soil organism, any organism inhabiting the soil during part or all of its life. 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 … The nutrients in the soil are rich. Healthy soils are the foundation of the food system. Let us … Soil distribution can impact rivers, lakes and streams, … The importance of soil and its uses include. 5 Uses of Soil Agriculture. The roots of... Building. 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

The soil is one of the most valuable natural resources available to us.
