The solid phase is a mixture of mineral and organic matter . Soil particles pack loosely, forming a soil structure filled with voids. The solid phase occupies about half of the soil volume. The remaining void space contains water (liquid) and air (gas). Contents Characteristics Formation In nature Uses ... edit Characteristics Darkened topsoil and reddish subsoil layers are typical in some regions. Soil color is the first impression one has when viewing soil. Striking colors and contrasting patterns are especially memorable. The Red River in Mississippi carries sediment eroded from extensive reddish soils like Port Silt Loam in Oklahoma . The Yellow River in China carries yellow sediment from eroding loessal soils.

en European Commission Environment Policies Contact ... Resources A strategy to keep Europe's soils robust and healthy Three components The making of the strategy Publications Contact information Different EU policies (for instance on water, waste, chemicals, industrial pollution prevention, nature protection, pesticides, agriculture) are contributing to soil protection. But as these policies have other aims and other scopes of action, they are not sufficient to ensure an adequate level of protection for all soil in Europe. For all these reasons, in September 2006, the Commission adopted a comprehensive EU strategy specifically dedicated to soil protection. The strategy is one of seven Thematic Strategies that the Commission has presented. The other strategies cover air pollution, the marine environment, waste prevention and recycling, natural resources, the urban environment and pesticides.. Three components The Thematic Strategy for Soil Protection consists of a Communication from the Commission to the other European Institutions, a proposal for a framework Directive (a European law), and an Impact Assessment. The Communication (COM(2006) 231) sets the frame. It explains why further action is needed to ensure a high level of soil protection, sets the overall objective of the Strategy and explains what kind of measures must be taken. It establishes a ten-year work program for the European Commission.

The Topic: Soils Easier - Soil is the loose top layer of our planet's crust. It is dirt or earth in which plant life can grow. Harder - Soil covers a major portion of the earth's land surface. It is an important natural resource that either directly or indirectly supports most of the planet's life. Life here depends upon soil for food. Plants are rooted in soil and obtain needed nutrients there. Animals get their nutrients from plants or from other animals that eat plants. Many animals make their homes or are sheltered in the soil. Microbes in the soil cause the breakdown and decay of dead organisms, a process that in turn adds more nutrients to the soil. Soil is a mixture of mineral and organic materials plus air and water. The contents of soil varies in different locations and is constantly changing. There are many different kinds and types of soils. Each has certain characteristics including a specific color and composition. Different kinds of soils support the growth of different types of plants and also determine how well that plant life grows. Soil is formed slowly, but can be easily destroyed. Therefore, soil conservation is important for continued support of life.

Soil makes up the outermost layer of our planet. Topsoil is the most productive soil layer. Soil has varying amounts of organic matter (living and dead organisms), minerals, and nutrients. Five tons of topsoil spread over an acre is only as thick as a dime. Natural processes can take more than 500 years to form one inch of topsoil. Soil scientists have identified over 70,000 kinds of soil in the United States. Soil is formed from rocks and decaying plants and animals. An average soil sample is 45 percent minerals, 25 percent water, 25 percent air, and five percent organic matter. Different-sized mineral particles, such as sand, silt, and clay, give soil its texture. Fungi and bacteria help break down organic matter in the soil. Plant roots and lichens break up rocks which become part of new soil.

Soil Types People describe soil types in all kinds of ways such as heavy, light, sandy, clay, loam, poor or good. Soil scientists describe soil types by how much sand, silt and clay are present. This is called texture . It is possible to change the texture by adding different things. Changing texture can help in providing the right conditions needed for plant growth. Sand is the largest particle in the soil. When you rub it, it feels rough. This is because it has sharp edges. Sand doesn't hold many nutrients. Silt is a soil particle whose size is between sand and clay. Silt feels smooth and powdery. When wet it feels smooth but not sticky. Clay is the smallest of particles. Clay is smooth when dry and sticky when wet. Soils high in clay content are called heavy soils. Clay also can hold a lot of nutrients, but doesn't let air and water through it well. Particle size has a lot to do with a soil's drainage and nutrient holding capacity. To better understand how big these three soil particles are, think of them like this. If a particle of sand were the size of a basketball, then silt would be the size of a baseball, and clay would be the size of a golf ball. Line them all up, and you can see how these particles compare in size.

Soil use, sustainability and conservation by Dr J Floor Anthoni (2000) www.seafriends.org.nz/enviro/soil/index.htm Soil is our most important resource, and also the most maligned and misunderstood. The world population will double in a mere forty years, but agricultural output is not keeping up with demand. In the process, precious soil is lost, waterways and coastal seas polluted. Humans obviously need to be much more knowledgeable about this problem. What is soil? Where does it come from? What kinds of soil exist? Are all soils fertile? How does soil work? Can all places on the planet be farmed? How much food can the planet make? How do we lose soil? How can we prevent erosion? What damage is caused by erosion? What is sustainability? Can soil be farmed sustainably? What can we do? introduction Introduction to this section on soil and erosion. If you're in a hurry, read this first. (on this page, 4 pages) dependence The human race depends on its agricultural soil for food. As the population doubles and the soils degrade, it will become a race between technology and dwindling natural resources in order to save mankind. (9 pages) geology Soils originate from the cauldron of Earth and are recycled and redistributed by the conveyor belts of plate tectonics. Although basic elements are fairly evenly spread, the rocks that contain them, are not. Soil is formed very slowly from the bedrock, under influence of climate and life. (10 pages)

Index to this page Soil Horizons Topsoil Subsoil Weathered parent material ... Deserts Soil Soil is the entry point for most materials into food webs . Through their roots, plants absorb water minerals (e.g., nitrates, phosphates, potassium, copper, zinc) With these, they convert carbon dioxide (taken in through their leaves) into carbohydrates proteins lipids nucleic acids and the vitamins on which all heterotrophs depend. Along with temperature and water, soil is a major determinant of productivity Soil Horizons Topsoil The very top layer consists of partially decayed organic debris like leaves. A soil profile characteristic of the plains states. The rainfall is so light that minerals in the soil are seldom carried below the subsoil. Beneath this is the topsoil. This horizon is usually dark in color because humus - partially decayed organic matter - which has been incorporated in it from above. Humus gives the soil a loose texture that holds water and allows air to diffuse through it. Oxygen is essential to permit cellular respiration in plant roots, decay organisms, and other inhabitants of the soil.
