  2. Soil survey - Wikipedia

    en.wikipedia.org/wiki/Soil_survey

    The information in a soil survey can be used by farmers and ranchers to help determine whether a particular soil type is suited for crops or livestock and what type of soil management might be required. An architect or engineer might use the engineering properties of a soil to determine whether it is suitable for a certain type of construction.

  3. Calcium deficiency (plant disorder) - Wikipedia

    en.wikipedia.org/wiki/Calcium_deficiency_(plant...

    Acidic, sandy, or coarse soils often contain less calcium. Uneven soil moisture and overuse of fertilizers can also cause calcium deficiency. At times, even with sufficient calcium in the soil, it can be in an insoluble form and is then unusable by the plant or it could be attributed to a "transport protein". [2]

  4. Physiological plant disorder - Wikipedia

    en.wikipedia.org/wiki/Physiological_plant_disorder

    Plant nutrient deficiencies can be avoided or corrected using a variety of approaches including the consultation of experts on-site, the use of soil and plant-tissue testing services, the application of prescription-blend fertilizers, the application of fresh or well-decomposed organic matter, and the use of biological systems such as cover ...

    Once assembled, the Foldscope is about the size of a bookmark. The Foldscope weighs 8 grams [citation needed] and comes in a kit with a lens that magnifies 140X. The kit also includes magnets that can be stuck onto the Foldscope to attach it to a smartphone, allowing the user to take pictures of the magnification. [2]

    Life cycle of the black rot pathogen, the gram negative bacterium Xanthomonas campestris pathovar campestris. Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1]

  8. 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.

  9. Determination (biology) - Wikipedia

    en.wikipedia.org/wiki/Determination_(biology)

    The science of identifying plant species using their pollen is called palynology. Geography can also sometimes help in narrowing down the identity of a specimen. Sometimes the determiner will be unable to identify a specimen clearly, and use such additions as cf. or aff. to convey this.
