    Plants are often grown in a soilless medium in order to supply the proper amounts of water and nutrients to the root zone as well as supplemental lighting to ensure a sufficient daily light integral. CEA plant growing optimizes the use of resources such as water, energy, space, capital and labor.

  3. 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 ...

    Hydroponics – a method of growing plants without soil. Intercropping – practice of growing two or more crops in proximity. Irrigation – artificial application of water to the land or soil. Permaculture – theory of ecological design which attempts to develop sustainable human settlements and agricultural systems modeled from natural ...

    Trees provide resources for the coffee plants such as shade, nutrients, and soil structure; the farmers harvest coffee and timber. Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. [1]

    en.wikipedia.org/wiki/Horticulture

    Environmental factors affecting plant development include temperature, light, water, soil pH, nutrient availability, weather, humidity, elevation, terrain, and micro-climate. [1] In horticulture, these environmental variables may be avoided, controlled or manipulated in an indoor growing environment.

  8. Agricultural cycle - Wikipedia

    en.wikipedia.org/wiki/Agricultural_cycle

    Irrigation is the process of artificially applying water to soil to allow plant growth. This term is preferably used when large amounts of water is applied to dry, arid regions in order to facilitate plant growth. The process of irrigation not only increases the growth rate of the plant but also increases the yield amount.

  9. Hydroponics - Wikipedia

    en.wikipedia.org/wiki/Hydroponics

    [27] [30] This is important as one of the most common errors when cultivating plants is over- and underwatering; hydroponics prevents this from occurring as large amounts of water, which may drown root systems in soil, can be made available to the plant in hydroponics, and any water not used, is drained away, recirculated, or actively aerated ...
