The Aquaponics


Cultivate out of the ground

The concept of plants that grow without land dates back to prehistoric times, think of the hanging gardens of Babilonia, the floods of the Nile that made the fields lush, the floating gardens of Mexico City: they are all examples of crops outside the soil of the past.

What does Acquaponica mean?

The term "water" comes from the Latin aqua,-ae that is brought back to the Indo-European root ak- with the meaning of bend and pόnos, work. Fold the Work.

It is a type of agricultural technique also known as "the art of growing plants in water". This technique, which does not use the earth but other substrates, is as old as the world, and has been recovered during this century in order to adapt the desire to make organic and intensive horticulture.

Where are plants grown outside the ground?

The plants are grown in different materials compared to the earth: expanded clay, perlite, volcanic lapilli, vermiculite, coconut fiber, rock wool cubes, zeolite, among others. In practice it is an inert and sterile substrate. Or directly in the water vertically or in NFT.

ADVANTAGES

Unlike all the techniques of cultivation out of the ground, the Aquaponics through the nitrogen cycle transforms ammonium and ammonia produced by the fish into nitrites and nitrates, the main nourishment of the plants. As the scientific literature highlights, the nitrifying microorganisms that populate the ecosystem, in addition to making the plants more vigorous, accelerate the phenological phases, their maturity that becomes anticipated and contemporary, defending the plant as if they constituted a real system immune. Aquaponics is the most profitable growing technique that exists.

Main applications of aquaponics

The soil cultivation technique in the aquaponic ecosystem allows to grow 100% organic plants with different application methods depending on the desired cultivations

Vertical cultivation


The vertical cultivation increases the convenience of the plant cost on the available space, optimizing the human labor cost. It is possible to use vertical cultivation to season or seasonally vary the production of plant plants (light conditions and controlled environment).

Nutrient film technique

In ducts / pipes arranged vertically or horizontally, the plants have predefined plant places subordinated to the chosen cultivation. Plants can have a germination substrate or a meshed mesh to promote contact with water.

Growth beds

Man-height cultivation environment with porous substrate (volcanic lapillus, expanded clay, zeolite, pumice stone) with water flow and reflux

Discover
Deep water culture

The plants are housed on rafts floating inside a water recycling tank. This technology is usually used for monocultures and allows both to grow all the plants simultaneously with the same maturity, or to create groups of crops to have a staggered maturity so do not wait for the entire life cycle for collection.

The scientific studies of dr. Nick Savidov

Known as the "Yoda" of Acquaponica, the internationally renowned senior researcher Dr. Nick Savidov, has been involved in Aquaponic research for over a decade.

His studies in Plant Molecular Biology at the University of Alberta continued with such success that he took the lead in the provincial research program on greenhouses in Brooks. Here he worked closely with the aquaculture researchers at Lethbridge College, making the transition from the Crop Diversification Center, which has been working in the field of off-soil cultivation for over 50 years, to the Aquaculture Center of Excellence without interruption.

The nitrogen cycle

The nitrogen cycle is the heart of organic agriculture and Acquaponica. There are several key elements in the nitrogen cycle, but nitrifying bacteria make the difference. Once the nitrifying bacteria are present, there are enough , begins the transformation of ammonium and ammonia into nitrites and nitrates, so we could say that the system "has a cycle".

The facts of the aquaponics

The Acquaponica wins on all fronts compared to traditional cultivation systems

· It is a permanent biodynamic permaculture: it allows to cultivate different crops within a small area;
· It is efficient and effective and allows obtaining results impossible with traditional cultivation methods;· Uses 90% less water (recycling of water with very little waste in the evaporation process);
· Uses a third of the energy of traditional cultivation because there is no use of chemistry and fossil sources;· Plants grow up to 50% faster, crops arrive in less time to ripening and fructification;
· The fruiting period is extended for a cultivation from 8 to 10 times greater: it is estimated that for each 453 gr of fish produced are obtained from 6 to 11 kg of vegetables;
· Over 40% less than human cost;
· Low carbon consumption because it does not use soil: in the US more than 20 megatons of carbon are dispersed in the environment by plowing the soil.

Cost comparison

· Aquaponics is cheaper: the return on investment for an aquaponics system is less than 5 years, while a farm requires a minimum of 8 years before growers can expect to see a portion of the profits that growers with aquaponics they will have already received for 5 or more years;

· Aquaponics remains the most sensible choice from an economic point of view, a way to produce organic food while respecting the environment.
