Fish Proteins and vegetable Vitamins from integrated farming, no oil, no fertilizer ?
No oil, no Fertilizer. The natural fertilizer from fish pond for vegetables is the alternative.
Closed loop Fish-Vegetables farming proteins and vitamins
Aquaponics fertilizes plant crops with bacteria-treated fish waste products. The plants return the favor by filtering the fish's water—and humans can eat both of them
GERM OF THE IDEA:
The heart of the aquaponic system is a bacterial bioreactor that converts fish-generated ammonia to plant-friendly nitrate in a two-step process. The plastic "wagon wheels" inside the bioreactor [inset] house colonies of Nitrosomonas and Nitrobacter, the two types of bacteria that process the ammonia. The wagon wheel is designed to maximize surface area and, hence, real estate for the bacterial colonies.
Confounded by the inexhaustible array of choices available when you stroll through a supermarket today? Well, here's another one to add to the list: How would you like your environmental degradation? By land or by sea? Whether it's pesticides and fertilizers leaching out of croplands or marine fish stocks vanishing by the boatful, every food purchase carries increasingly visible ecological costs.
Against this backdrop, a growing cadre of academics, farmers and aquaculturists is working to refine and popularize a technique that could slash those costs for both fish and vegetable products. The technique, dubbed "aquaponics," integrates fish farming and hydroponic agriculture in a sort of closed, symbiotic loop—the fish serve as fertilizer factories, the plants as water purifiers. The idea is to maximize food production while minimizing environmentally taxing inputs and potentially polluting outputs—a sustainable approach to growing healthy food.
At Cabbage Hill Farm in Mount Kisco, N.Y., a sizable aquaponic greenhouse offers an established proof of concept.
