NASA researcher checking hydroponic onions with Bibb lettuce to his left and radishes to the right Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent.[1] Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can be from fish waste, duck manure, or normal nutrients. History[edit] In 1929, William Frederick Gericke of the University of California at Berkeley began publicly promoting that solution culture be used for agricultural crop production.[3][4] He first termed it aquaculture but later found that aquaculture was already applied to culture of aquatic organisms. Reports of Gericke's work and his claims that hydroponics would revolutionize plant agriculture prompted a huge number of requests for further information. Techniques[edit] Static solution culture[edit]

100 years ago, people were eating things that most of us will never taste. So what happened? Narrator: In 1905, a book called The Apples of New York appeared. It featured hundreds of Apples with names like Westfield Seek-No-Further or Esopus Spitzenburg, a favorite of Thomas Jefferson. If it wasn't for preservationists for like Ron Joyner in Lansing, North Carolina‎, most apples including the Virginia Greening, an apple dating back to the 1700 with thick green skin and yellow, coarse, and sweet flesh would no longer exist. It isn't just apples. Farming the Cities, Feeding an Urban Future WASHINGTON - June 16 - As people move from rural to urban settings in search of economic opportunities, urban agriculture is becoming an important provider of both food and employment, according to researchers with the Worldwatch Institute. "Urban agriculture is providing food, jobs, and hope in Nairobi, Kampala, Dakar, and other cities across sub-Saharan Africa," said Danielle Nierenberg, co-director of the Institute's Nourishing the Planet project. "In some cases, urban farmers are providing important inputs, such as seed, to rural farmers, dispelling the myth that urban agriculture helps feed the poor and hungry only in cities." The United Nations projects that up to 65 percent of the world's population will live in cities by 2050, up from around 50 percent today. The rate of urban migration is particularly high in sub-Saharan Africa and South Asia, where inadequate urban infrastructure struggles to keep up with the large influx of people.

Progressive Plant Growing is a Blooming Business Progressive Plant Growing is a Blooming Business Soil. Water. Say that plants don't need them and people may think you've traded your cow -- and your good sense -- for a handful of beans. But NASA-sponsored plant experiments prove that you don't need soil and lots of water to grow a beanstalk that would make Jack proud. Plants have been to space since 1960, but NASA's plant growth experiments began in earnest during the 1990s. Growing Hydroponic Tomatoes Home Page This interactive web site provides practical, accurate information on growing hydroponic tomatoes for students, hobbyists, and beginning growers. Hydroponic culture is one of the most exacting and intensive methods of crop production used in agriculture today. Over the last 20 years, great advances in hydroponic technology have been made through extensive research and development programs in the United States and Europe. And although hydroponics may be technology and capital intensive, it is also extremely productive and efficient in its water and land use. Whether your interest in hydroponics is as a hobby, an additional source of income, or you want to get into the commercial market, the future and opportunities in soilless culture are more favorable today than ever before. We hope this introduction to hydroponic tomato growing will spark your interest, provide information, and lead you other resources available in print and on the web.

A rooftop fish farm for every family? It may look nothing more than an oddly shaped greenhouse, but the 'Globe (hedron)' is a concept for a rooftop aquaponics dome that Urban Farmers hopes will help address global food security Image Gallery (11 images) It may look nothing more than an oddly shaped greenhouse, but the "Globe (hedron)", a collaboration by food futurists Urban Farmers AG and and designer Antonio Scarponi of Conceptual Devices, is a concept for a self-contained rooftop aquaponics dome that its designers hope will help address global food security. The company is seeking funding to turn the concept into a prototype. View all Aquaponics is a marriage of aquaculture (farming aquatic animals, like fish or prawns) and hydroponics (growing plants in water).

NOLA Gets First Aeroponic Urban Farm Louisiana-based Aquaponic Modular Production Systems , an urban agriculture development company, just announced the debut of a project — the first aeroponic farm in New Orleans. The Tower Garden is hosted by Hollygrove Farm and Market to showcase an innovative, fast, and eco-friendly way to grow fresh produce for the community. The design is a closed-loop system that uses nutrient-enriched water, not soil, to grow food. The recirculating farm has no water runoff and is expected to yield upwards of 40 pounds of greens per week, according to a statement by AMPS. AMPS says The Tower Garden can “ efficiently capture and repurpose waste, recycle water to reduce consumption, and grow food virtually anywhere – indoors or outside and in oddly shaped spaces. “ It’s made with food-safe plastic suitable for outdoor use and allows 44 plants to grow in five square feet.

Design Probes - Urban beehive The design of the beehive is unconventional, appealing, and respects the natural behavior of the bees. It consists of two parts: entry passage and flower pot outside, and glass vessel containing an array of honeycomb frames, inside. The glass shell filters light to let through the orange wavelength which bees use for sight. Startup Profile: AeroFarms - Urban Agriculture Aeroponic Systems March 29, 2011 | Robert Puro People are moving in ever increasing numbers from rural areas into urban city centers. Global population is expected to increase by nearly 40% to 9 billion people in the next 40 years. Threats to agriculture from climate change, loss of arable land, pesticide resistance, and water shortages continue to grow more acute.
