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. 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.[2][3] He first termed it aquaculture but later found that aquaculture was already applied to culture of aquatic organisms. Two other plant nutritionists at the University of California were asked to research Gericke's claims. Origin[edit] Soilless culture[edit]
Fisheries & Aquaculture - Aquaculture Aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish. The need to exchange reliable information on all related subjects is becoming a key issue for the responsible management of aquaculture.In order to provide easily-accessible and up-to-date information, the FAO Fisheries and Aquaculture Department has developed specific pages on aquaculture where users can consult relevant material on aquaculture at international, regional and national level. The Global Synthesis of aquaculture development status and trends, andsix Regional Reviews of aquaculture development, status and trends. Fact Sheets Aquaculture Fact Sheets contain a synthesis of detailed information on specific subjects and include related statistics, graphics (GIS maps, images, figures, etc.) and profiles. The Fact Sheets cover the following information domains: Statistical information This includes statistics and databases related to aquaculture.
Raising tilapia at home Raising Tilapia at home Trying to be self sufficient in these troubled times is not easy, though it probably never has been easy.

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.
Facts About Abalone Facts About Abalone Classification In the animal kingdom, abalone belong to the phylum Mollusca, a group which includes clams, scallops, sea slugs, octopuses and squid. Mollusks are world wide and predominantly marine. They have a soft body surrounded by a mantle, an anterior head and a large muscular foot. The abalone join other snails, whelks and sea slugs in the class Gastropoda. Anatomy The most conspicuous part of any abalone is the shell, with its row of respiratory pores. Anatomy of an Abalone with Shell Removed The internal organs are arranged around the foot and under the shell. The gill chamber is next to the mouth and under the respiratory pores. Abalone Life Cycle Commercial Abalone Species FISHTECH INC. works with the following species: Red Abalone FISHTECH INC. works with 14 different species of abalone worldwide. Reproduction The sexes are separate and can be distinguished in individuals as small as one inch when the gonads begin to develop. Food Manufactured food: Predation.
A Millionaire on One Acre with Aquaponics Become a Millionaire on One Acre with Aquaponics - by Colle Davis, Phil Estes and Phyllis Davis The most common request we receive from those would like to become a commercial aquaponics farmer is from people who already have the land and want to cover it in aquaponics installations, BUT they do not have the money to make the initial investment. The majority of the extremely valuable information that we had previously provided in this article for free of charge is now included in our Portable Farms® Aquaponics System Course: CLICK HERE for more information. The numbers are impressive. However, this investment is NOT for the faint of heart or for the passive investor looking for a super safe investment. This project requires hard work, focus and dedication on the part of everyone involved.
Very Edible Gardens Grow The Easiest Garden on Earth Gardening for Life - Discovering New Ways To Feed The World 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. 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. “There are a lot of solar cookers out there,” says Wilson, “but surprisingly not many using latent-heat storage as an attribute to cook the food.” A group of MIT students are working with the technology to develop a prototype solar grill. + Solar Grill on Barbecue Lovers Via Treehugger Images ©Derek Ham
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.
