  2. Soil quality - Wikipedia

    en.wikipedia.org/wiki/Soil_quality

    Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...

  3. Soil organic matter - Wikipedia

    en.wikipedia.org/wiki/Soil_organic_matter

    Soil represents one of the largest C sinks on Earth and is significant in the global carbon cycle and, therefore, for climate change mitigation. [6] Therefore, SOM/SOC dynamics and the capacity of soils to provide the ecosystem service of carbon sequestration through SOM management have received considerable attention.

  4. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    The term natural cycling appears in a 1968 paper on the transportation of leaf litter and its chemical elements for consideration in fisheries management: "Fluvial transport of tree litter from drainage basins is a factor in natural cycling of chemical elements and in the degradation of the land."

  5. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.

  6. Soil ecology - Wikipedia

    en.wikipedia.org/wiki/Soil_ecology

    Soil microbial communities experience shifts in the diversity and composition during dehydration and rehydration cycles. [5] Soil moisture affects carbon cycling a phenomenon known as Birch effect. [6] [7] Temperature variations in soil are influenced by factors such as seasonality, environmental conditions, vegetation, and soil composition.

  7. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Soil fertility is a complex process that involves the constant cycling of nutrients between organic and inorganic forms. As plant material and animal wastes are decomposed by micro-organisms, they release inorganic nutrients to the soil solution, a process referred to as mineralization. Those nutrients may then undergo further transformations ...

  8. Health and environmental effects of transport - Wikipedia

    en.wikipedia.org/wiki/Health_and_environmental...

    A European study of nearly 2000 participants showed that an average person cycling 1 trip/day more and driving 1 trip/day less for 200 days a year would decrease mobility-related lifecycle CO 2 emissions by about 0.5 tonnes over a year, representing a substantial share of average per capita CO 2 emissions from transport (which are about 1.5 to ...

  9. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    The phrase "soil health" has largely replaced the older "soil quality". The primary difference between the two expressions is that soil quality was focused on individual traits within a functional group, as in "quality of soil for maize production" or "quality of soil for roadbed preparation" and so on.
