Index to this page Soil Horizons Topsoil Subsoil Weathered parent material ... Deserts Soil Soil is the entry point for most materials into terrestrial 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 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. Subsoil The subsoil is usually lighter in color that topsoil and often contains an accumulation of inorganic nutrients.

Soil ecology From Wikipedia, the free encyclopedia Jump to: navigation search Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. It is particularly concerned with the cycling of nutrients , formation and stabilization of the pore structure , the spread and vitality of pathogens , and the biodiversity of this rich biological community Contents Overview Features of the ecosystem Soil food web Research ... edit Overview Soil is made up of a multitude of physical chemical , and biological entities, with many interactions occurring among them. Soil is a variable mixture of broken and weathered minerals and decaying organic matter. Together with the proper amounts of air and water, it supplies, in part, sustenance for plants as well as mechanical support. The diversity and abundance of soil life exceeds that of any other ecosystem . Plant establishment, competitiveness, and growth is governed largely by the ecology below-ground, so understanding this system is an essential component of plant sciences and terrestrial ecology. edit Features of the ecosystem Moisture itself becomes a major limiting factor on land. Terrestrial organisms are constantly confronted with the problem of dehydration. Transpiration or evaporation of water from plant surfaces is an energy dissipating process unique to the terrestrial environment.

But ultimately it's not office buildings or jobs that give us our checks. It's the soil. The soil is what gives us the real income that supports us all” ~ Ed Begley, Jr. “History is largely a record of human struggle to wrest the land from nature, because man relies for sustenance on the products of the soil. So direct is the relationship between soil erosion, the productivity of the land, and the prosperity of people, that the history of mankind, to a considerable degree at least, may be interpreted in terms of the soil and what has happened to it as the result of human use.” ~ Hugh H. Bennett and W.C. Lowdermilk, circa 1930s “... if this is to be a permanent nation we must save this most indispensable of all our God-given assets the soil, from which comes our food and raiment. If we fail in this, remember that much sooner than we have expected this will be a nation of subsoil farmers.” ~ Hugh H. Bennett (1933)

Institute for Environment and Sustainability Welcome to the European Soil Portal This Soil Portal contributes to a thematic data infrastructure for soils in Europe. It presents data and information regarding soils at European level. It connects to activities within JRC concerning soil (JRC SOIL Action). It serves also as a vehicle to promote the activities of the European Soil Bureau Network. Spatial data collection and processing within this infrastructure is performed according to emerging ideas behind the INSPIRE (Infrastructure for Spatial Information in Europe) initiative. The European Soil Data Center is one of the ten environmental data centres in Europe and is the focal point for soil data at European level. Soil Datasets : The European Soil Portal contains currently many soil data, maps, information, Atlases and applications; most of the offered data are at European scale, while, when possible, links to national or global datasets are provided. Soil at JRC : Soil activities within the JRC are concentrated in a specific JRC Action, called FP7 "Soil Data and Information Systems" or SOIL.

72. REAL TREES 4 Kids! - Soil soil . One of the first things you probably learned about plants was that they needed certain things to live and grow — water, sunlight, and soil. http://www.realtrees4kids.org/ninetwelve/soil.htm

Home Contact Information About the Project FAQ ... What's the System? Soil soil . Plants use these to live and grow and each has its own job in the larger system . This section takes a closer look at soil. Soil doesn't come "one-size-fits-all." Each species of plant needs the soil it lives in to meet its specific needs in order to grow successfully. This is true for all plants — from the tallest trees to the tiniest sprouts. Understanding this is important for all of us, but especially those who cultivate plant crops. Finding a good combination of soil and tree species can mean the difference between a healthy tree crop or a poor one. REAL TREE growers need to learn all they can about the soils available on their operations. They must become agronomists. Growers use the work of pedologists (those who study the soil) and their own knowledge of how trees and soils work together to make good decisions about what species of conifers to plant and how to cultivate what they have planted.

ILLUSTRATION: ELAYNE SEARS Article Tools Image Gallery Print E-mail Comments ... RSS Most organic gardeners find that following nature’s patterns serves them well. When it comes to building richer soil, nature’s plan relies heavily on trees — fallen limbs, leaves, cones, seeds and, eventually, the massive trunks. Adapting this plan to your garden by using a wood mulch — such as wood chips, sawdust or other woody residues — as soil-building material is a strategy that promises huge, long-term returns.

CONTACTS About Us Vision Since its inception in 1999, Pedosphere.com aimed to become an extensive repository of Soil Science knowledge through partnerships with major international organizations and also be an active player in global Soil Science education by creating high quality, interactive resources that engage both students and instructors. The development of internet technologies has lead to a glut of information, therefore, there is a tremendous need to organize information, convert it to knowledge and manage the knowledge for specific purposes such as global education. The original aims of becoming key Soil Science knowledge managers and active global educators is now entering its second phase of actualization. Inspiration The most inspiring statement that is driving us is the following excerpt from remarks by His Highness the Aga Khan at the State Banquet (Dhaka, Bangladesh) on 19 May 2008: "Technology is also transforming our economic lives. Economic value is no longer tied to how much land one controls - or how many machines or factories one owns. Within our lifetimes, predominantly "Agricultural Societies" and "Industrial Societies" of the past have been joined - and sometimes supplanted - by what many call the "Knowledge Society," propelled by the digital revolution, and focusing on the creation and management of information. In a Knowledge Society, the most productive investments we can make are investments in education."
