  2. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  3. Edaphology - Wikipedia

    en.wikipedia.org/wiki/Edaphology

    In terms of soil chemistry, it places particular emphasis on plant nutrients of importance to farming and horticulture, especially with regard to soil fertility and fertilizer components. Physical edaphology is strongly associated with crop irrigation and drainage. Soil husbandry is a strong tradition within agricultural soil science.

  4. Soil health - Wikipedia

    en.wikipedia.org/wiki/Soil_health

    Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota , plants and animals.

  6. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Soil has four important functions: as a medium for plant growth; as a means of water storage, supply, and purification; as a modifier of Earth's atmosphere; as a habitat for organisms; All of these functions, in their turn, modify the soil and its properties. Soil science has two basic branches of study: edaphology and pedology.

  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. 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.

  9. Soil biology - Wikipedia

    en.wikipedia.org/wiki/Soil_biology

    Soil biology is the study of microbial and faunal activity and ecology in soil. Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.
