Vermiponics
Vermiponics is a soil-less growing technique that combines hydroponics with vermiculture by utilizing diluted wormbin leachate ("worm tea") as the nutrient solution as opposed to the use of fish waste (as used in aquaponics) or the addition of manufactured chemicals to provide the nutrients. In 2008, Saginaw Valley State University in Michigan was using vermiponics as part of its efforts to reduce waste. Aquaponics growers have noted previously that redworms can be added to aquaponic grow beds successfully and serve useful functions in aquaponic systems. This has led several people to experiment with nutrient solutions that are based on wormbin leachate alone, for instance in a Central Queensland University trial. The effectiveness of vermiponics compared to hydroponics and aquaponics has not been thoroughly studied. However, a paper from the University of Arizona has found that using wormtea has beneficial effects on root protrusion in lettuce seedlings when compared to inorgan ...

Vermiculture
Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, while the rearing of worms for this purpose is called vermiculture. Vermicast (also called worm castings, worm humus, worm manure, or worm faeces) is the end-product of the breakdown of organic matter by earthworms. These excreta have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting. Vermicompost contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner.Coyne, Kelly and Erik Knutzen.

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. As existing hydroponic and aquaculture farming techniques form the basis of all aquaponic systems, the size, complexity, and types of foods grown in an aquaponic system can vary as much as any system found in either distinct farming discipline. History Aquaponics has ancient roots, although there is some debate on its first occurrence: *Aztec cultivated agricultural islands known as '' chinampas'' in a system considered by some to be an early form of aquaponics for agricultural use, where plants were raised on stationary (or sometime movable) islands in lake shallows and waste materials dredged from the Chinampa canals and surrounding cities were used to manually irrigate the plants. * South China and the whol ...

Hydroponics
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 aqueous solvents. Terrestrial or aquatic plants may grow with their roots exposed to the nutritious liquid or in addition, the roots may be mechanically supported by an inert medium such as perlite, gravel, or other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution by secondary metabolites. Transgenic plants grown hydroponically allow the release of pharmaceutical proteins as part of the root exudate into the hydroponic medium. The nutrients used in hydroponic systems can come from many different organic or inorganic sources, including fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions. Plants are commonl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saginaw Valley State University
Saginaw Valley State University (SVSU) is a public university in University Center, Michigan in Saginaw County. It was founded in 1963 as Saginaw Valley College. It is located on in Saginaw County's Kochville Township, approximately north of downtown Saginaw. Saginaw Valley State is the newest of Michigan's 15 public colleges and universities. SVSU offers over 100 academic programs at the undergraduate and graduate levels with approximately 8,500 students at its main campus in University Center. SVSU offers programs of study in its five colleges. History Higher education in the Saginaw Valley region dates back to the founding of Bay City Junior College in 1922. Though the junior college was replaced by Delta College in 1961, the area still lacked a four-year baccalaureate institution. Saginaw Valley College was founded as a private institution in November 1963, and became a state-supported institution in 1965. The name changed to Saginaw Valley State College in 1974 and agai ...

Food Waste
Food loss and waste is food that is not eaten. The causes of food waste or loss are numerous and occur throughout the food system, during production, processing, distribution, retail and food service sales, and consumption. Overall, about one-third of the world's food is thrown away. A 2021 metaanalysis that did not include food lost during production, by the United Nations Environment Programme found that food waste was a challenge in all countries at all levels of economic development. The analysis estimated that global food waste was 931 million tonnes of food waste (about 121 kg per capita) across three sectors: 61 per cent from households, 26 per cent from food service and 13 per cent from retail. Food loss and waste is a major part of the impact of agriculture on climate change (it amounts to 3.3 billion tons of CO2e emissions annually) and other environmental issues, such as land use, water use and loss of biodiversity. Prevention of food waste is the highest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Technology
Agricultural technology or agrotechnology (abbreviated agtech, agritech, AgriTech, or agrotech) is the use of technology in agriculture, horticulture, and aquaculture with the aim of improving yield, efficiency, and profitability. Agricultural technology can be products, services or applications derived from agriculture that improve various input/output processes. Advances in agricultural science, agronomy, and agricultural engineering have led to applied developments in agricultural technology. History The history of agriculture has been shaped by technological advances. Historians have described a number of agricultural revolutions, which identify major shifts in agricultural practice and productivity. These revolutions have been closely connected to technological improvements. Irrigation technology was developed independently by a number of different cultures, with the earliest known examples dated to the 6th millennium BCE in Khuzistan in the south-west of present-day Iran. ...
