  2. Root rot - Wikipedia

    en.wikipedia.org/wiki/Root_rot

    Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...

    en.wikipedia.org/wiki/Pyrenochaeta_lycopersici

    [3] [6] These microsclerotia can survive under harsh environments such as temperature changes and drought, and they can maintain the ability to infect other hosts in the soil for up to 15 years. [7] Once the environment becomes favorable for the pathogen growth, germination will occur in microsclerotia that leads to the production of hyphae . [ 6 ]

  4. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    Under controlled laboratory conditions hydroponic solutions are periodically pH adjusted to near neutral (pH 6.0) and are aerated with oxygen. Also, water levels must be refilled to account for transpiration losses and nutrient solutions require re-fortification to correct the nutrient imbalances that occur as plants grow and deplete nutrient ...

  5. Houseplant - Wikipedia

    en.wikipedia.org/wiki/Houseplant

    Root rot is the most common cause of death for houseplants but keeping houseplants too dry ("under-watering") can also be detrimental. Plants require nitrate , phosphate , and potassium to survive, as well as micronutrients including boron , zinc , manganese , iron , copper , molybdenum , and chlorine .

  6. Pythium - Wikipedia

    en.wikipedia.org/wiki/Pythium

    Pythium-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. [2] Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to Pythium. [3]

  7. Ebb and flow hydroponics - Wikipedia

    en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

    Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition to the plants but which anchors the roots and functions as a temporary reserve of water and solvent mineral ...

  8. Aquaponics - Wikipedia

    en.wikipedia.org/wiki/Aquaponics

    Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.

  9. Heterobasidion annosum - Wikipedia

    en.wikipedia.org/wiki/Heterobasidion_annosum

    Heterobasidion annosum moves short distances from the roots of an infected stump through root grafts with other trees. It can also spread through insects that feed on roots. [1] [6] Since this fungus can not move very far through soil, it relies on tree roots to help it infect neighbouring trees. In these roots, it can grow 0.1–2.0 m per year.
