Fine as long as you can get the necessary nutrients into the system. For example, a lot of the P in the foliage of well-fertilised plants can be present as orthophosphate
Good points Paul. Organic hydroponics is very much a strong possibility. Role of microbial consortium seems to play bigger role than conventional method of microbial inoculation ..
Organic hydroponics is a good and relevant farming system especially in urban farming system where native soil is polluted with heavy metals. it is also highly applicable in greenhouse for the production of highly demanded vegetables like tomato and lettuce. It helps plants to get the required amount of all the essential nutrents.
There is no organic hydroponics system. There should not be.
In regular hydroponic system, you know what you are going to put into the system (which chemicals) and you know and you can predict which/what reactions are going inside the system.
When it comes to organic people do believe that you have to choose not to use pesticides, fertilizers, GMO, antibiotics and growth hormones. So you are going to use different kind of natural organic extracts, for a example you are going to apply different kind of herbal extracts / solutions as pesticides ! No one knows what actual all chemical properties of the system.
So when it comes to organic hydroponics, you have to convert all the inputs into liquid media (even the soil / nutrients), there will be thousands of unknown properties in the system.
As I believe we can not omit 100% everything, There should be a balance!
it seems so interesting
organic and hydroponic farming make great economic and environmental impact saving. (such as hydroponic forage for livestock sector)
if combination of these two be possible, these savings would be greater.
Thank's for all. want to discuss this new topic with my colleagues and see if possible the realization of this project.
It is good, but this depend in the availability of water.
I am not too sure , whether organic hydroponics is commercially used , but its a novel concept , we need to work on it ...
Some forms of soiless culture appear more organic than others. Some initiative is required to be more carefully define the differences because the current standards are vague. A possible start would be to distinguish between cultures that do and don’t include microbial activity. The prospect of attaching an organic label to hydroponic products presents an enormous marketing opportunity for growers and marketers. Yet at some point inclusiveness may begin to dilute the integrity of the product.. Source : Based on discussion from Rupert Jannasch
Organic hydroponics vs. conventional hydroponics
Definition of 'organic' product, the synthetic fertilizer should not be used. What kind of fertilizer we should use to grow plants in 'organic' hydroponics is a focus.
This is where , the real challenge lies ,the organic hydroponics , but surely its harder ...
The United States is one of the few countries that allows hydroponics to be labeled organic. Mexico, Canada, Japan, New Zealand, and 24 European countries (including Holland, England, Germany, Italy, France, and Spain) all prohibit hydroponic vegetable production to be sold as organic in their own countries. This means “organic” hydroponic producers in other countries are often growing exclusively for a U.S. market.Presently, the vast majority of the “hydroponic organic” produce sold in this country is grown in Mexico, Canada, or Holland.
