How are soils and climate related?
Soils and global warming. Soils and climate have always been closely related. The predicted temperature increases due to global warming and the consequent change in rainfall patterns are expected to have a substantial impact on both soils and demographics.
What are the two cycles of soil?
Carbon and nitrogen cycles. Soils are dynamic, open habitats that provide plants with physical support, water, nutrients, and air for growth. Soils also sustain an enormous population of microorganisms such as bacteria and fungi that recycle chemical elements, notably carbon and nitrogen, as well as elements that are toxic.
How does carbon enter the ecosystem?
Carbon (C) also enters the ecosystem from the atmosphere—in the form of carbon dioxide ( CO 2 )—and is taken up by plants and converted into biomass. Organic matter in the soil in the form of humus and other biomass contains about three times as much carbon as does land vegetation. Soils of arid and semiarid regions also store carbon in inorganic chemical forms, primarily as calcium carbonate (CaCO 3 ). These pools of carbon are important components of the global carbon cycle because of their location near the land surface, where they are subject to erosion and decomposition. Each year, soils release 4–5 percent of their carbon to the atmosphere by the transformation of organic matter into CO 2 gas, a process termed soil respiration. This amount of CO 2 is more than 10 times larger than that currently produced from the burning of fossil fuels (coal and petroleum), but it is returned to the soil as organic matter by the production of biomass.
How does agriculture affect soil carbon?
A large portion of the soil carbon pool is susceptible to loss as a result of human activities. Land-use changes associated with agriculture can disrupt the natural balance between the production of carbon-containing biomass and the release of carbon by soil respiration. One estimate suggests that this imbalance alone results in an annual net release of CO 2 to the atmosphere from agricultural soils equal to about 20 percent of the current annual release of CO 2 from the burning of fossil fuels. Agricultural practices in temperate zones, for example, can result in a decline of soil organic matter that ranges from 20 to 40 percent of the original content after about 50 years of cultivation. Although a portion of this loss can be attributed to soil erosion, the majority is from an increased flux of carbon to the atmosphere as CO 2. The draining of peatlands may cause similarly large losses in soil carbon storage.
How much carbon is stored in plants?
Carbon that is stored in terrestrial plants mainly through photosynthesis is called net primary production or NPP and is the dominant source of food, fuel, fibre, and feed for the entire population of Earth. Approximately 55 billion metric tons (61 billion tons) of carbon are stored in this way each year worldwide, most of it in forests.
What is an ecosystem?

When nutrient cycling or the effects of management practices on soils are being considered, ...
How does soil form?
Soil forms through the weathering of rock and the action of organisms on organic matter.
What is the role of soil in the ecosystem?
As a recycler of raw materials, soil performs one of its greatest functions in the global ecosystem. Decomposition of dead plants, animals, and organisms by soil flora and fauna (e.g., bacteria, fungi, and insects) transforms their remains into simpler mineral forms, which are then utilized by other living plants, animals, and microorganisms in their creation of new living tissues and soil humus.
What are the functions of soil?
Soils perform five key functions in the global ecosystem. Soil serves as a: 1 medium for plant growth, 2 regulator of water supplies, 3 recycler of raw materials, 4 habitat for soil organisms, and 5 landscaping and engineering medium.
How does soil store carbon?
Through the processes of decomposition and humus formation, soils have the capacity to store great quantities of atmospheric carbon and essential plant nutrients. This biologically active carbon can remain in soil organic matter for decades or even centuries. This temporary storage of carbon in the organic matter of soils and biomass is termed carbon sequestration. Soil organic carbon has been identified as one of the major factors in maintaining the balance of the global carbon cycle. Land management practices that influence soil organic matter levels have been extensively studied, and are often cited as having the potential to impact the occurrence of global climate change.
Why do soil organisms need organic material?
In addition to the need for suitable habitat, all soil organisms require some type of organic material to use as an energy and carbon source, that is to say they require food. An abundant supply of fresh organic materials will ensure a robust population of soil organisms. Quiz.
Why does soil absorb water?
As rain or snow falls upon the land, the soil is there to absorb and store the moisture for later use. This creates a pool of available water for plants and soil organisms to live on between precipitation or irrigation events. When soils are very wet, near saturation, water moves downward through the soil profile unless it is drawn back towards the surface by evaporation and plant transpiration.
Which soil texture has the least impact on decomposition rate?
Correct: All soil textures contain decomposing organisms and will support this function if water and oxygen are present, and the soil temperature is greater than 5 degrees Celcius (~ 40 F). Thus, soil texture will have the least impact on decomposition rate of this group of soil properties.
What is soil used for?
Soil serves as a: medium for plant growth, regulator of water supplies, recycler of raw materials, habitat for soil organisms, and. landscaping and engineering medium.
