Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment. Terrestrial or aquatic plants may grow freely with their roots exposed to the nutritious liquid or the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates.
Vegetable farming is the growing of vegetables for human consumption. The practice probably started in several parts of the world over ten thousand years ago, with families growing vegetables for their own consumption or to trade locally. At first manual labour was used but in time livestock were domesticated and the ground could be turned by the plough. More recently, mechanisation has revolutionised vegetable farming with nearly all processes being able to be performed by machine. Specialist producers grow the particular crops that do well in their locality. New methods—such as aquaponics, raised beds and cultivation under glass—are used. Marketing can be done locally in farmer's markets, traditional markets or pick-your-own operations, or farmers can contract their whole crops to wholesalers, canners or retailers.
Aquaponics is a food production system that couples aquaculture with hydroponics whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the Greek words aer ("air") and ponos ("work"). It falls under the category of hydroponics, as water is employed in aeroponics to deliver nutrients to the plants.
A market garden is the relatively small-scale production of fruits, vegetables and flowers as cash crops, frequently sold directly to consumers and restaurants. The diversity of crops grown on a small area of land, typically from under 0.40 hectares to some hectares, or sometimes in greenhouses, distinguishes it from other types of farming. A market garden is sometimes called a truck farm in the USA.
A herb farm is usually a farm where herbs are grown for market sale. There is a case for the use of a small farm being dedicated to herb farming as the smaller farm is more efficient in terms of manpower usage and value of the crops on a per acre basis. In addition, the market for herbs is not as large as the more commercial crops, providing the justification for the small-scale herb farm. Herbs may be for culinary, medicinal or aromatic use, and sold fresh-cut or dried. Herbs may also be grown for their essential oils or as raw material for making herbal products. Many businesses calling themselves a herb farm sell potted herb plants for home gardens. Some herb farms also have gift shops, classes, and sometimes offer food for sale. In the United States, some herb farms belong to trade associations.
Container gardening or pot gardening/farming is the practice of growing plants, including edible plants, exclusively in containers instead of planting them in the ground. A container in gardening is a small, enclosed and usually portable object used for displaying live flowers or plants. It may take the form of a pot, box, tub, basket, tin, barrel or hanging basket.
Vertical farming is the practice of growing crops in vertically stacked layers. It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. Some common choices of structures to house vertical farming systems include buildings, shipping containers, underground tunnels, and abandoned mine shafts.
Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with plants floating in Styrofoam boards on top. This method of floating the boards on the nutrient solution creates a near friction-less conveyor belt of floating rafts. DWC, along with nutrient film technique (NFT), and aggregate culture, is considered to be one of the most common hydroponic systems used today. Typically, DWC is used to grow short-term, non-fruiting crops such as leafy greens and herbs. DWC was invented accidentally in 1998 by a legacy cannabis grower who goes by the name of “Snype”. This occurred because “Snype” and his (unnamed) associate had to take a trip to Amsterdam and needed a way to feed their cannabis crop while they were away. They built nutrient and water reservoirs that would keep the plants thoroughly fed in their absence, and thusly the DWC system was born. They revised this system in 2010 to create RDWC. The large volume of water helps mitigate rapid changes in temperature, pH, electrical conductivity (EC), and nutrient solution composition.
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. Production takes place within an enclosed growing structure such as a greenhouse or plant factory.
Urban horticulture is the science and study of the growing plants in an urban environment. It focuses on the functional use of horticulture so as to maintain and improve the surrounding urban area. Urban horticulture has seen an increase in attention with the global trend of urbanization and works to study the harvest, aesthetic, architectural, recreational and psychological purposes and effects of plants in urban environments.
Intensive crop farming is a modern industrialized form of crop farming. Intensive crop farming's methods include innovation in agricultural machinery, farming methods, genetic engineering technology, techniques for achieving economies of scale in production, the creation of new markets for consumption, patent protection of genetic information, and global trade. These methods are widespread in developed nations.
Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
Agriculture in the United Arab Emirates, including fishing, was a minor part of the UAE economy in the early 1990s, contributing less than 4 percent of GDP. Since the formation of the UAE, the availability of capital and the demand for fresh produce have encouraged agricultural development. The main farming areas are Digdaga in Ras al-Khaimah. Falaj al Mualla in Umm al Qawain, Wadi adh Dhayd in Sharjah, Al Awir in Dubai and the coastal area of Al Fujairah. Total cultivable land was around 70,000 hectares as of the early 1990s.
A hanging garden is a form of sustainable landscape architecture that can take several different forms, such as roof gardens, but will always be defined as a garden planted at a suspended or elevated position off the ground. These gardens are created with walls, fences, planted on terraces, growing from cliffs, or anything where the garden is not touching the earth. Space optimization is the main intention with the gardens, however, aesthetics and providing cleaner air are also popular reasons for setting one up. Hanging gardens are popular in urban environments where there is limited space, such as in New York or California.
Agricultural machinery relates to the mechanical structures and devices used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. Agricultural machinery can be regarded as part of wider agricultural automation technologies, which includes the more advanced digital equipment and robotics. While agricultural robots have the potential to automate the three key steps involved in any agricultural operation, conventional motorized machinery is used principally to automate only the performing step where diagnosis and decision-making are conducted by humans based on observations and experience.
A Windowfarm is a hydroponic urban gardening system that was originally developed by Britta Riley using open-source designs. A Windowfarm is an indoor garden that allows for year-round growing in almost any window. It lets plants use natural light, the climate control of your living space, and organic “liquid soil.”
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required. The Kratky method has applications both for commercial food production and as a small-scale and low-maintenance technique for home growers. It has been described as "the simplest hydroponic system."
