  2. 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 ...

  3. Iron deficiency (plant disorder) - Wikipedia

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

    Iron deficiency can be avoided by choosing appropriate soil for the growing conditions (e.g., avoid growing acid loving plants on lime soils), or by adding well-rotted manure or compost. If iron deficit chlorosis is suspected then check the pH of the soil with an appropriate test kit or instrument. Take a soil sample at surface and at depth.

  4. 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]

  5. Plant–soil feedback - Wikipedia

    en.wikipedia.org/wiki/Plantsoil_feedback

    Negative plantsoil feedback is thought to be an important factor in helping plants to coexist. If a plant is over-abundant, then soil pathogens and other negative factors will become common, hurting its growth. [2] Similarly, if a plant becomes overly rare, then so too will its soil pathogens and other negative factors, helping its growth. [2]

  6. Plant disease epidemiology - Wikipedia

    en.wikipedia.org/wiki/Plant_disease_epidemiology

    Imaging-based approaches for the detection has two main methods, fluorescence imaging and hyper-spectral imaging. Fluorescence imaging helps identify the metabolic conditions of the plant. In order to do so, a tool is used to present light onto the chlorophyll complex of the plant. [7] Hyper-spectral imaging is used to obtain reflected images.

  7. Boron deficiency (plant disorder) - Wikipedia

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

    Boron is present in the soil in many forms, the most common being boric acid (H 3 BO 3). An adequate amount of boron in the soil is 12 mg/kg. An adequate amount of boron in the soil is 12 mg/kg. If the boron content of the soil drops below 0.14 mg/kg then boron deficiency is likely to be observed.

  9. Nitrogen deficiency - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_deficiency

    A young cabbage plant exhibiting nitrogen deficiency. Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. [1] Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1]
