There are various methods of cultivation of plants without soil. It is a hydroponics – supply of nutritious solution to roots of plants, an aeroponik – dispersion of nutritious structure on roots of plants and an agroponik – cultivation in an aquarium, the pool or other closed system in common of fishes and plants.
What is the agroponik
The method agroponik is of great interest to small homestead farms and at the same time is widely used in industrial farms. Joint keeping of fish and plants in one biosystem allows to increase production efficiency and to lower material and labor costs. The products can be received all the year round. There is no need for installation of expensive systems of supply of nutritious solution.
Agroponik the same principle of a hydroponics, cultivation of plants without soil is the cornerstone. Only food of a plant is received from water in which there live fishes. In an aquarium which contains fishes products of their exchange which contain the substances necessary for development of plants collect. These substances can be used for cultivation of vegetable and other cultures (for example, strawberries), as nutritious.
At traditional methods of cultivation, in the soil, the basis of nitric food of plants is formed by nitrates. Even when entering into soil only of ammonium forms of fertilizers, a plant all the same eat nitrates and accumulate them that does harm to human health. The fact is that lack of air in the soil and a lack of humidity quickly turn ammonium into nitrates. What does not occur in an aquarium or the pool.
Method essence
In the systems of the closed water supply grow up many cultures, tomatoes, cucumbers, a wild strawberry, strawberry, salads. Usually industrial complexes have difficult designs, but it is possible to apply capacity from transparent glass to house use. If you wish to grow up large fish, for example carps, capacity has to be 1.5 meters in length, width and depth. It is filled with water for 83%. On a bottom seaweed land and fish is started. Due to photosynthesis of seaweed, water is enriched with oxygen. Plants are located from above in a hydroponic system which occupies 15% of aquarium volume. The hydroponic system represents a plastic cellular design platform in which roots of plants are protected by the small cellular grid protecting them from eating by fishes. In the center – an opening for feeding of fishes. Between the platform and water – the airspace 2 centimeters which is not allowing to rot to roots of plants. The efficiency of a method depends on a proper correlation of quantity of plants and fishes. Nutrients which are formed of waste of activity of fishes has to be enough for food of plants.
