The term "vertical farming" was coined by Gilbert Ellis Bailey in 1915 in his book Vertical Farming.His use of the term differs from the current meaning—he wrote about farming with a special interest in soil origin, its nutrient content and the view of plant life as "vertical" life forms, specifically relating to their underground root structures.

Emerging in North America in the 1970s and 1980s, vertical tillage (VT) is a system of principles and guidelines similar to conservation agriculture (CA) in that it aims to improve soil health, increase water infiltration and decrease soil erosion and compaction (improve bulk density).
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
Findbusinesses4sale explored what the rise of vertical farming can mean for domestic food production, using Department of Agriculture data.
Space optimization: Vertical farming and advanced control technologies maximize the use of limited spaces. Resource management: Reduced water and fertilizer consumption through the recycling of nutrient solutions. Protection for sensitive species: Controlled conditions shield plants from climatic extremes, pests, and diseases.
In practice, vertical farms employ advanced techniques such as hydroponics or aeroponics, allowing plants to grow without soil by using nutrient-rich water or air instead. By utilizing vertical space, these farms achieve higher crop yields per square foot compared to conventional farming methods.
Green wall at the Simon Fraser University, Burnaby, British Columbia, Canada.. A green wall is a vertical built structure intentionally covered by vegetation. [1] Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt; as well as an integrated hydration and fertigation delivery system.
[34] [35] AeroFarms, leveraging Harwood's patented aeroponic technology, currently operates the largest indoor vertical farm in the world based on its annual growing capacity in Newark, New Jersey. This state-of-the-art farm employs aeroponic technology to produce and distribute up to two million pounds of pesticide-free leafy greens each year.
