Green Society. Hydroponics. NASA researcher checking hydroponic onions with Bibb lettuce to his left and radishes to the right Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, biochar, mineral wool, expanded clay pebbles or coconut husk. Researchers discovered in the 18th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. History[edit] Reports of Gericke's work and his claims that hydroponics would revolutionize plant agriculture prompted a huge number of requests for further information.
Origin[edit] Soilless culture[edit] Advantages and disadvantages[edit] Aquaponics. System combining aquaculture with hydroponics in A symbiotic environment A small, portable aquaponics system. The term aquaponics is A portmanteau of the terms aquaculture and hydroponic agriculture. Aquaponic greenhouse in Apaga Aquaponics () refers to 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 hydroponic grown plant, involving nitrifying bacteria for converting ammonia into nitrates. As existing hydroponic and aquaculture farming techniques form the basis for 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.[1] History[edit] Aquaponics has ancient roots, although there is some debate on its first occurrence: Parts of an aquaponic system[edit] A commercial aquaponics system.
Plants[edit] How One Startup Sold $6,000 Worth of Charcoal on Kickstarter. Name: re:char Big Idea: Utilize organic waste to create carbon-negative charcoal, a substance that pulls CO2 from the air and helps crops grow taller and stronger. Why It's Working: Re:char's mission is about providing farmers — both at home and in developing countries such as Kenya — with conservation-oriented soil-boosting complexes that can double food output compared to traditional farming methods. How do you convince longtime traditional farmers that they could produce 200% more food every crop season if they mix their soil with specially-designed charcoal?
For Jason Aramburu and his company re:char, talking Kenyan farmers into using its "biochar" product proved to be a major challenge. "It's hard to get them to do anything out of their routine because it's very risky for them, especially when you're talking about their livelihood," says Aramburu. But once they saw the bountiful corn stalks that re:char could grow on Kenyan soil, they began to listen.

Wilson Solar Grill Stores the Sun's Energy For Nighttime Grilling. Many of us will be firing up our grills this weekend for some well-deserved barbecue time. After all, barbecuing is one of America’s greatest pastimes, but it certainly isn’t one of our most environmentally friendly. Whether you prefer charcoal, wood chips or propane, grilling releases emissions and contributes to poor air quality.
Up until now, solar powered grilling has required, as you might expect, the sun, which means traditional fuel-fired grills are required after sunset. But new solar technology developed by MIT professor David Wilson could bring a nighttime solar-powered grill to the market very soon; an invention also of great benefit to those in developing nations who rely on wood to cook all their food. Wilson’s technology harnesses the sun and stores latent heat to allow cooking times for up to an amazing twenty five hours at temperatures above 450 degrees Fahrenheit. A group of MIT students are working with the technology to develop a prototype solar grill. Via Treehugger. Milan's Vertical Forest.
Wednesday, 12 October 2011 GreenMuze Staff Milan’s Vertical Forest from Stefan Boeri Architects. The Bosco Verticale (Vertical Forest) will be the greenest building in Milan when completed, which is one of Europe’s most polluted cities. Designed by Stefan Boeri Architects, as part of their BioMilano vision to incorporate 60 abandoned farms into a greenbelt surrounding the city. The Bosco Verticale building has a green façade planted with dense forest systems to provide a building microclimate and to filter out polluting dust particles.
The living bio-canopy also absorbs CO2, oxygenates the air, moderates extreme temperatures and lowers noise pollution, providing aesthetic beauty and lowering living costs. Each apartment balcony will have trees (900 plantings are planned for the two buildings) that will provide shade in the summer and drop their leaves in winter to allow in winter sunlight. Plant irrigation is provided via a grey-water filtration. Via Inhabitat. Future Orchard Trust | Nurture the Future. Future Orchard Trust.

Welcome to the 21st Century posted on Monday, July 11, 2011 04:08 PM Welcome to the 21st century, an age of amazing capabilities that were but dreams decades ago, and unimaginable centuries before that. Sadly, those capabilities that are not being utilized to their maximum potential for the largest benefit to mankind. To that end, it is unconscionable that any human being on the planet should go hungry, especially given our advanced technical capability to assist in producing food with minimal human labor input. It's time 17th century agricultural practices make way for more robust and efficient methods. Can we solve world hunger? "We can't solve problems by using the same kind of thinking we used when we created them.

Description The idea is to convert a negative space into one that creates benefit for the community Urban Farm has secured workshops & 400sqm's of rooftop space in Dublin city centre where we are researching and demonstrating intensive urban growing techniques.
We have begun building facilities to host events & community groups and provide hands-on workshops that teach responsible food production, carpentry, energy-saving systems, ecological cycles, and community self-sufficiency observing organic & pesticide free practices. We go beyond the normal timber yards and builders suppliers, all materials used are salvaged from waste, diverted from landfill, de-constructed & up-cycled on site.We compost on the rooftop with the help of City Composting Ltd, a new start-up company helping to lower the volume of city waste.
