We have bees and butterflies and helpful insects that keep away pests and so forth. In her view, Cufone and farmers like her embody the spirit of sustainability and responsibility that customers look for in an organic product. Dixon is the chief scientist for the Cornucopia Institute, a group that represents small farmers and has become a major voice in opposition to hydro-organics.
Cornucopia firmly believes that the organic certification should go only to farmers who grow in soil. Their argument against hydro-organic agribusiness is multi-fold. First is their belief in the inherent superiority of soil-grown produce. Kastel repeatedly cited the superior flavor and nutritional content of soil-grown vegetables.
The former claim varies based on crop. Proper soil-based organics ensures healthy soil for generations, allows for thriving communities of beneficial insects, and, in turn, an entire ecosystem around them. Organics is about the planet beyond the pepper, they say. But probably mostly money. Cornucopia made it a point to say that they approve in spirit of small, sustainable hydro producers like Cufone; they think that stuff is cool, or at least cute.
But they do not believe it should ever be labeled organic. It is monstrously huge business, which is the only reason many farmers put up with the equally huge amounts of red tape it takes to actually get the certification. An organic farmer can charge as much as twice the price for the same item — and work very hard for the ability to do so. This is all legal at the moment, keep in mind; Cornucopia is fighting to strengthen the restrictions on organic farmers, in a way that would box out those who, in their mind, are unworthy of the organic label.
Both of those companies have gigantic organic hydroponic businesses, selling tomatoes, cucumbers, squash, peppers, and berries, which are grown, in some capacity, in hydroponic greenhouses.
Hydro-organics often does not include any outside interaction with the planet at all, being less spooky than Kastel thinks they are but no less hermetically sealed.
When I presented that to Cufone, she protested. A lot of people do multiple forms of growing on a farm. The bigger argument is about money, as the end of most arguments are. Turning a conventional soil-based farm into an organic farm is much, much more involved; you have to allow the soil to recover for three years before you can call your food organic. That enables big business like Wholesum Harvest to pump their low-cost organics into the market, boxing out smaller, older producers.
I offered a few possible solutions to this issue, all of which…failed. What about a totally new label, I asked both Cufone and the folks from Cornucopia?
Has a nice ring to it, right? Cornucopia said sure, who cares, they can do whatever they want. Cufone thought this was a great idea. The Cornucopia people, not so much. That includes hydroponics, aquaponics, rooftop farming, container farming, all of it. There is no conclusion on the future of organics.
It is a complete mess. A Indian entrepreneur has sold me two plant Beds one has volcanic rock material could be perlite or vermiculite he does not want to share the details on top of that he has spread moss etc. The Second Bed has earthworms and again moss as a top cover. Both these have a common reservoir with one submerged pump, The Beds have some sort of vertical offtakes pipes to not allow flooding. The excess water goes back to the reservoir.
Please help me understand this!! Many thanks Best regards. All articles All categories. Farm to Table Looking for inspiration after harvest?

Dec 7, What Is Organic? What Is Hydroponics? Organic Hydroponics? Aquaponics Some certified organic hydroponic growers combine aquaculture AKA fish farming to provide nutrients to their plants.

In recirculating tanks, build-up of nutrients and bacteria can rapidly reduce oxygen levels, like algal blooms do when too much agricultural runoff seeps into the water. Of course, roots also require oxygen, and if they are deprived of it plant growth will quickly cease. This problem is not limited to organic systems — conventional hydro systems can also get clogged up with roots, algae, bacteria and all kinds of organic gunk.
Another major difficulty when using organic nutrients in a hydroponic system particularly a substrateless system is ensuring that sufficient nutrients are available to the plant.
Hydroponic systems allow plants to take up water and nutrients at significantly increased rates compared to soil. This speeds up growth and yield and shortens overall harvest time.
But it also requires nutrients to be constantly available at optimum concentrations. In conventional hydro, this is achieved by using mineral salts that the plant can immediately utilize. Organic farming instead relies on the presence of microbial life to break down complex organic molecules into simpler forms.
This will likely lead to deficiencies and stunted growth as the plant takes up some nutrients and not others. This problem is not just limited to hydroponics — even in soil-based organic growing, providing sufficient nitrogen and certain other nutrients often presents difficulties. In practice, this has sometimes led to vegetable farmers supplementing their organic crops with inorganic nutrients.
So, anyone wishing to successfully implement fully-organic hydroponics must ensure that a rich microbial population is supported, so that the biological reactions necessary to feed the plants can happen at a fast enough rate. The beating heart at the center of organic hydroponics is the biofilter. In general, a biofilter is a system that takes in large, complex organic molecules and breaks them down into simpler molecules, with the help of oxygen and biological catalysts such as microbes!
All organic hydroponics systems depend on the existence of a biofilter, based on microbial catalysts to break down the complex nutrients and deliver them to the plants. In essence, the biofilter is doing the job that soil usually does.
In systems that are based on the use of a substrate, the substrate beds themselves can act as the biofilter. This is true of many aquaponic systems — it just depends on providing enough surface area, oxygen and nutrients for thriving microbial life to develop.
There are various forms of organic hydroponic systems in use today. Arguably the best-known form of organic hydroponics is aquaponics, which we will describe in the next section.
Then, very similar to aquaponics, we have vermiponics — which uses worms instead of fish to break down complex nutrients. As the name implies, this system relies on the dissolved nutrients in human urine pee! As urine contains abundant nitrogen, phosphorus, potassium and sulphur, along with an array of trace minerals, it provides excellent nutrition for plants.
Peeponics is quite close in concept to bioponics, another main type of organic hydroponics that we shall discuss in more detail soon. Both rely on fully dissolved nutrients, and do not require an intermediary like fish or worms to break down complex molecules. Aquaponics uses solely organic nutrients and delivers them via a system of recirculating tanks and pumps.
