The hydroponic has several positive aspects, and it is used globally, especially for the production of food, but also for different elaborate crops: it is, for all intents and purposes, a recognized part of agronomy. The advantages of ‘ aquaculture are mainly represented by:
it is not required the use of soil so that this hydroponic cultivation can be implemented even in areas unfavorable from the viewpoint associated with climate or soil;
Administration of vitamins occurs in a controlled, so you cannot experience the waste associated with the actual spreading of fertilizers on the soil, where some can be washed aside by rain or made unavailable simply by chemical reactions. This results even in the absence of pollution for the environment and to the flaps. Similarly, you do not go through the deficiencies sometimes associated with crops in the ground, where some nutrients may be seen in limited amounts;
Since the water could be reused within the system, are reduce water requirements for the crops. In some instances, it also comes to save 70-80% of water. This allows you to build in areas that are particularly dried out, and save on the costs of irrigation;
are minor attacks by parasites, viruses, and pathogens that normally have a home in the soil; in the case of disease, it is easier to intervene with all the treatment plant protection;
the presence involving herbs weed is virtually tending to zero, and this avoids the using herbicides;
the yields are high and stable, and can be from 2 to 8 times greater than the growth on your lawn;
cultivation can be carried out throughout every season because, under controlled conditions, and next gets rid of the seasonal specifications of the species. You can also grow completely inside a grow tent.
Among the downsides of hydroponics, we first mention the fragility of the program. Since plants do not have his or her roots in the soil but are completely dependent on artificial sustenance, any difficulty to the technical system can cause rapid death of the crops. The high level of moisture associated together with hydroponics, moreover, favors the development associated with fungal diseases such as wilt.
The techniques of hydroponic cultivation
The particular nutrients used in hydroponics cultivation techniques (also known as hydroponics ) are dissolved in water, and is represented by ions (positively charged) and cations (negative) as
calcium (Ca ++ )
magnesium (Mg ++ )
potassium (K + )
nitrate (NO 3 – )
sulfate (SO 2 – )
dihydrogen phosphate (H 2 PO 4 – )
Typically, the solution is added in addition several essential micronutrients such as
Very useful are the chelating brokers, which maintain the iron in the remedy, making it available to plants, and nutrients such as amino acids and vitamins that can be directly consumed by the plant roots, stimulating emergence and fruit enlargement.get more facts at http://www.bbc.com/news/business-35098045
As plants digest nutrients dissolved in the water might result in changes in the pH of the solution, which can then become more acid (low pH) or alkaline (high pH). It is, therefore, advisable to check constantly the values of pH and the concentration involving nutrients to avoid way too sharp fluctuations compared to optimal levels. In addition to these parameters, must be kept under control the conductivity and particular electrical parameters related to the move (flow and timing). It is recommended to measure the pH at least once a day, and especially right after giving nutrients that may alter the idea.
The hydroponic solutions can be bought ready-made from the manufacturers and the most gardening stores supplied: it is formulated concentrates that are dissolved in the water following the instructions on the recording label. To love instead devote themselves to you to DIY a good solution is for you to resort to the use of a few software for free (see link at the bottom of page). Even without owning large chemical knowledge, hydroponics enthusiasts may make use of these programs, created by professional chemists to prepare in your home hydroponic alternatives best suited to their plants.
