  2. Soil test - Wikipedia

    en.wikipedia.org/wiki/Soil_test

    A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.

  3. Soil morphology - Wikipedia

    en.wikipedia.org/wiki/Soil_morphology

    The table below displays the deal bulk densities that both allow and restrict root growth for the three main texture classifications. The porosity of a soil is an important factor that determines the amount of water a soil can hold, how much air it can hold, and subsequently how well plant roots can grow within the soil. [14] Soil porosity is ...

  4. Random dot stereogram - Wikipedia

    en.wikipedia.org/wiki/Random_dot_stereogram

    A random-dot stereogram (RDS) is stereo pair of images of random dots that, when viewed with the aid of a stereoscope, or with the eyes focused on a point in front of or behind the images, produces a sensation of depth due to stereopsis, with objects appearing to be in front of or behind the display level.

  5. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch ...

  6. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Plants hold soil against erosion, and accumulated plant material build soil humus levels. Plant root exudation supports microbial activity. Animals serve to decompose plant materials and mix soil through bioturbation. [70] Soil is the most speciose (species-rich) ecosystem on Earth, but the vast majority of organisms in soil are microbes, a ...

  7. Stereopsis (fungus) - Wikipedia

    en.wikipedia.org/wiki/Stereopsis_(fungus)

    Stereopsis is the sole genus of fungi in the family Stereopsidaceae. [1] The genus was formerly placed in the family Meruliaceae in the order Polyporales but was found to belong in its own order along with the genus Clavulicium. [1] Stereopsis was circumscribed by English mycologist Derek Reid in 1965. [2]

  9. Glossary of plant morphology - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_plant_morphology

    Such specialised plant parts may arise from the stems or roots. Examples include plants growing in unfavourable climates, very dry climates where storage is intermittent depending on climatic conditions, and those adapted to surviving fires and regrowing from the soil afterwards. Some types of plant habit include:
