Bioponics
a new vision of hydroponics 
of Noucetta Kehdi
The hydroponics has become in our days the current practice of cultivation, which farmers recognize the many benefits. Particularly affects the wealth and quality of crops, but also the positive action undertaken in the ecological field, thanks to an important saving water and fertilizer that this system allows, on our planet where water is becoming a rare commodity and the ' contaminated soil and groundwater is increasingly alarming. The technology then attracts the attention of growers who are considering, however, a recurring question: is organic hydroponics? In fact, it is not hydroponics, as such, which must be organic or not, because there is nothing more than a cultivation technique.
The issue is rather the fertilizers used: you can use organic fertilizer in hydroponics and hydroponic cultivation can be organic?
How to feed the plants?
The information on the nutrition of plants, and especially the difference between organic and mineral nutrition, is still rather vague nowadays.
Indeed, the excesses resulting from industrial crops and their degree of pollution that characterize our planet push public opinion to reject the so-called fertilizer "chemical," which in reality, especially for large brands, are nothing more than refined mineral salts purified.
The plants shall procure nourishment by absorbing a number of minerals, nutrients and proportions vary according to their needs and their growth cycle. These salts are essentially primary elements: nitrogen (N), phosphorus (P) and potassium (K), secondary elements are: calcium (Ca), sulfur (S) and magnesium (Mg) and trace elements: boron (Bo), Copper (Cu), iron (Fe), chlorine (Cl), cobalt (Co), manganese (Mn), molybdenum (Mo), silicon (Si) and zinc (Zn). The whole is absorbed in the form of ions dissolved in oxygen and water constitutes the nourishment of plant, regardless of the use of an organic or mineral fertilizer.
Obviously for an optimal growth and development, the plant needs also to light, heat, moisture, air, treatment, care and so on.
From the point of view of the plant, therefore, is not the origin of the salts made that matters, but a combination of factors: that the fertilizer used contains all the necessary salts and water that is suitable to use, soft or hard .
E 'is the case of mineral fertilizers hydroponic quality, which are generally produced with salts refined and perfectly soluble and which have been totally deprived of heavy metals and pollutants.
The user perspective
From the point of view the situation is different. As for the nutrition of the plant there is no intrinsic difference between a mineral and an organic fertilizer, and mineral fertilizers are not as such a concern, but rather the abuse that has been made over time.
If the farmer wishes to maximize his crop harvests and lush, while worrying about the purity of his crop, has every incentive to choose a high quality mineral fertilizer, complete and suitable for the type of water.
In cultivation mineral, as in biological evolution, it is important to know how to handle the products properly, paying attention to balance skillfully and with knowledge of the right time for intervention. Following a system of rational nutrition and a method of integrated pest management, ie using natural predators to combat and prevent diseases and pests, gives results far superior to those obtained with other types of fertilizer.
There remains the issue of potential toxicity of nutrients, since this is the first consumer gripe: the danger does not depend on whether the organic fertilizer is less, but the composition of the fertilizer and the doses and routes of administration.
A high-end mineral hydroponic fertilizer is designed to leave no trace in plants, provided you follow the manufacturer's recommendations for use. In fact, adding too much fertilizer or not adequately monitoring the pH level, you run the risk of poison plants, or cause shortages.
However there is also the possibility of poisoning the plants with the use of organic fertilizer: the United States, where organic farming has developed on a large scale for over 25 years, we regularly read articles reporting food poisoning caused by mismanagement of organic crops, sometimes even leading to serious accidents.
It 's so good to reiterate that the term "organic" is not in itself guarantee security, and that the key to a healthy crop is not so much in the product used, as in the manner in which it is managed.
In choosing an organic fertilizer can take over other issues, political considerations result of the concept of sustainable development and the growing respect for social and environmental criteria "econologici" (union of 'economic' and 'green') current.
When the cultivation is carried on for its own sake, without necessarily go looking for high productivity, increases the possibility of moving towards alternatives: the choice to consume organic produce, fair and durable is very agreeable, and some researchers have addressed their efforts in this direction
Years of experiments have recently allowed the development of organic fertilizers that are applied effectively in hydroponics.
Success is important: so far as to produce fertilizers s'ignorava completely adequate.
The point was to obtain complete fertilizers in which all the elements could be certified as organic, and perfectly soluble, to avoid the risk of rot or water filters or bloccassero drippers and the firm is not easy because organic fertilizers are usually composed of large organic molecules are difficult to dissolve.
Are also formulated to degrade slowly in the ground, and some of their components rot in the water, releasing a rather unpleasant odor.
The biponia is a method of growing revolutionary that allows a hydroponic cultivation which is 100% organic.
This new method of cultivation goes far beyond a simple change of fertilizer, the concept is that of "liquid earth" in conjunction with other products such as Trichoderma harzianum and silicate dust, fertilizer bioponic in the nutrient solution can make all relevant information for the plant.
The clear water is already present, and also oxygen in abundance if the cultivation system is designed properly, will be sufficient to add Trichoderma harzianum, the microorganisms that make microbial life and are part of the carbon cycle.
If you want you can add the silica in the form of powder, or a product about the silicates and metals: you get a nutrient solution which has the same characteristics of a good ground light, airy, rich in nutrients and microbial life, which not missing nothing but an inert medium, such as clay pebbles or coconut fiber.
The biponia is difficult to apply?
We are often asked if the biponia technology is difficult.
It must be said that this is a somewhat 'different from that to which the user is used for hydroponics.
For what concerns the basic criteria of a crop parameters remain the same: humidity, temperature, ventilation, prevention of diseases and insects, hygiene areas of cultivation, etc.. However the management of pH and EC levels will be changed.
In hydroponics the most work is done on the basis of the reading levels of pH and EC: To ensure a perfect absorption of minerals and to protect the chelates that are contained in fertilizers (good quality), it is important to maintain the level pH between 5.5 and 6.5.
Also to ensure a correct level of nutrition, is added to the fertilizer when the EC will fall below the level necessary to the needs of the plant, as a function of its cycles of growth (generally: + / - 0.4 for the cuttings, + / - 1.0 for the young plants and + / -1.3 for adult plants and mother plants).
In biponia the pH level is less important than all'idroponia.
It will always have a tendency to rise, but up to a value of 7.5 did not find any problems: it is scientifically proven that plants are living well with pH levels ranging from 5.0 to 7.5. Moreover, even in hydroponics is recommended not to intervene too often on the pH, but to let oscillate in the range between 5.5 and 6.5, since the addition of acids frequently do not have particularly beneficial.
Values greater than 7.5 require intervention to restore the pH to the value of 6.0, but in a progressive way, diluted in a period of a few days.
For pH adjustment, unfortunately, there are no biological additives effective and the most suitable product is represented by acids of good quality, which include organic buffers to stabilize the level as much as possible.
It recommends in particular do not use vinegar, as some suggest to do, since the acid
acetic acid is harmful to plants.
With regard to the level of EC, this represents a parameter very complicated in biponia: in fact, the organic molecules do not possess electric charge, and will not therefore be detected by the reader CEs.
During the dilution of the fertilizer in the water each tiny fraction will be immediately transformed into ions, providing a slight conductivity.
With a dose from 4 to 5 ml / l of fertilizer bioponic and with the normal conductivity of the water of the water network, is normally achieved a value of about 0.65 (0.6 to 0.7): this conductivity, albeit low, it is generally sufficient and the 'addition of fertilizer will be needed only the value will drop further.
As the elements are released, are gradually absorbed and the conductivity remains stable when the reserves of organic matter are scarce, tends to go down and you need to fertilize. It seems easy enough, but for best results you must anticipate the fall of conductivity and assure a steady supply of organic matter, without exaggeration, because their degradation is a function of the heat.
Microorganisms (Trichoderma harzianum) act in incredibly different speeds depending on temperature, and if there is too much organic matter present in the system, a sudden warming could raise the conductivity to a level that kill the plant.
It is not always easy to find the right fit, and it is in these cases that the eye of the farmer informed makes the difference.
Do not worry, even beginners can use this technique, you can simply read the instructions for use, and detailed information on the data sheets of fertilizers bioponici not hesitate to contact the manufacturer to ask him any questions that may come to your mind.
The biponia a technique is not particularly complicated, it is merely a different approach.
What are the advantages of biponia?
The biponia is based on the principles of a rational, which is to provide a few nitrates to the plant to encourage flowering and fruiting, vegetative growth rather than getting so abundant, but sometimes useless.
This is the reason for which will find that the foliage of your plants is not as green as that obtained from mineral fertilizers and with certain traditional organic manures.
This is a very interesting aspect of this type of cultivation: vegetable mass is formed very little in relation to the yield.
The biponia dell'idroponia and combines the advantages of organic farming.
Saves a lot of water and fertilizer, as well as expensive and bulky substrates, and to cultivate organic crops at 100% of small areas.
In conclusion, and to answer another frequently asked question concerning bioponici fertilizers should be added that these products can be used with good results even in the ground.
Can be administered with the watering, drop by drop, for irrigation and fertilizer.
