The Geo-Hydroponic System, or simply Geo-Hydroponics, was recently developed in Brazil, and though it is still being studied, it has already demonstrated its eficiency and economy.

As in Aquaponics, it uses animal excrements, but from terrestrial origin, bred under captivity or in confinement.

We can use many types of animal manure, ranging from cattle to caged birds, such as laying hens.

It is very important that those excrements are originated from animals bred in complete confinement, to avoid undesirable contaminations in them.

That is why manure from laying hens have been the most commonly used, not only because they are very easy to collect, but also because many parallel benefits can be obtained using them.

For instance, one can't help but despise the sanitation and odor problem that large quantities of hen manure represent on egg farms.

In this situation Geo Hydroponics provides the ideal solution for that problem.

Regardless of the manure utilized, it must be processed in an Anaerobic Biodigester, in order to obtain complete biodigestion.

The final product obtained from biodigestion is the Biofertilizer, a highly concentrated solution of mineral, organo-mineral and organic salts, of highly nutritious value for the plants.

The biofertilizer is submitted to a series of controls, dosed, diluted with water, thus producing a nutrient solution, that can be used in any hydroponic system.

On the surface, this process appears very simple, but it requires a series of controls, which must be carried with extreme diligence.

The critical element of the system, is the construction and proper handling of a Biodigester, a type of equipment which unfortunately is not commonly used today.

As with Aquaponics, this system is very friendly to the sorrounding environment, as it is not destructive to it.

On the contrary, it helps to keep it clean.

Each of the steps of this process, are absolutelly natural, and are under our complete control.

In contrast to Aquaponic System, our nutrient solution is not subject to the control of the equilibrium of two antagonistic biomasses.

Therefore this simplifies our tasks.

Regardless, all the controls needed for properly maintainig inorganic nutrient solutions should be observed here.
