Certification of hydroponic, aquaponic, and aeroponic operations is allowed under the USDA organic regulations, and has been since the National Organic Program began. For these products to be labeled as organic, the operation must be certified by a USDA-accredited certifying agent, and maintain compliance with the USDA organic regulations.
“Celiac disease, and, more generally, gluten intolerance, is a growing problem worldwide, but especially in North America and Europe, where an estimated 5% of the population now suffers from it,” researchers wrote in a meta-analysis of nearly 300 studies. “Here, we propose that glyphosate, the active ingredient in the herbicide, Roundup®, is the most important causal factor in this epidemic,” they add.
Aeroponics is a relatively new way of growing plants that is getting increasingly popular with many people because of the speed, cost, and novelty. Aeroponics only came about during the 1940s, and since then, many researchers have added to the theory and application of this method. It seems to me, one of the best ways to grow plants in a soil-free environment, with the exception of hydroponics. If you have little space for a garden in the form of land, or if your soil isn’t particularly arable, why not try aeroponics?
Plants have been to space since 1960, but NASA's plant growth experiments began in earnest during the 1990s. Experiments aboard the space shuttle and International Space Station have exposed plants to the effects of microgravity. These experiments use the principles of aeroponics: growing plants in an air/mist environment with no soil and very little water.
Aeroponics is a method of growing plants in a moist environment. The plants are suspended in an enclosed setting and water, mixed with plant food, is sprayed onto the roots. Aeroponics systems are frequently employed in an enclosed environment like a greenhouse so that the temperature and humidity can be accurately regulated. Although sunlight is the principal light source, some additional lighting may also be added.
IME claim that water requirements to meet food demand in 2050 could reach between 10-13.5tn cubic metres per year - about triple the current amount used annually by humans. Meat production requires a much higher amount of water than vegetables. IME state that to produce 1kg of meat requires between 5,000 and 20,000 litres of water whereas to produce 1kg of wheat requires between 500 and 4,000 litres of water.
According to the FAO, agricultural production is a huge driver of climate change, producing one-fifth of total greenhouse gas (GHG) emissions. Intensive farming methods use fertilizers and pesticides that contaminate streams and rivers that can create downstream “dead zones,” and deforestation for agricultural use accounts for an estimated 10-11% of global GHG emissions.
