An organic garden on a school campus. Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
In America, vegetable farms are in some regions known as truck farms; "truck" is a noun for which its more common meaning overshadows its historically separate use as a term for "vegetables grown for market". Such farms are sometimes called muck farms, after the dark black soil in which vegetables grow well.
Row crops typically have low biomass and shallow roots: this means the plant contributes low residue to the surrounding soil and has limited effects on structure. [11] With much of the soil around the plant exposed to disruption by rainfall and traffic, fields with row crops experience faster break down of organic matter by microbes, leaving ...
The choice of growing media and components to the media help support plant life. Within a greenhouse environment, growers may choose to grow their plants in an aquaponic system where no soil is used. Growers within a greenhouse setting will often opt for a soilless mix which does not include any actual components of naturally occurring soil.
Plant domestication is seen as the birth of agriculture. However, it is arguably proceeded by a very long history of gardening wild plants. While the 12,000 year-old date is the commonly accepted timeline describing plant domestication, there is now evidence from the Ohalo II hunter-gatherer site showing earlier signs of disturbing the soil and cultivation of pre-domesticated crop species.

Since soil-based organic agriculture uses less pesticides, it has lower toxic residues than plants grown with inorganic fertilizer by approximately 75%. [ 5 ] [ 6 ] While there is inconclusive research on whether it is more nutritious than conventional agriculture, a meta analysis of plant nutrition found that soil-grown organic food is higher ...
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.
Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55] Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems.
