Strictly speaking, the question of what ishydroponics, you can answer simply and clearly - this is a special technique by which you can grow plants. And quite often this method is the best. All gardeners know that the land under the plants requires constant loosening, because they need not only water and soil minerals, but also air for normal growth and gas exchange. When growing vegetables and green plants hydroponically, the soil and other soil fillers are not used, the rootlets of the plants are constantly in the solution necessary for their normal development of fertilizers.
What happens to plants usually?
Roots provide the ground part with all necessarynutrients. But here there is one nuance - these useful minerals can be absorbed only in dissolved or diluted form. Soil becomes a kind of substrate, which contains substances that dissolve during irrigation. A different situation in hydroponics. If you use only water for irrigation, the plants will die. That's partly the answer to the question of what hydroponics is - a complex system that allows the plant to get all the necessary nutrients. Most enterprises in agriculture have already switched to the use of this system for a long time.
Features hydroponics
In the hydroponics system, syntheticfibers that do not allow the solutions in them to evaporate too quickly and do not enter into chemical reactions with them. The porous structure transmits an optimal amount of oxygen to the roots. Thus, the substrate in relation to plants becomes completely inert. You can easily imagine what hydroponics is. Thanks to this system, plants get enough nutrition for their proper full development, which allows achieving high stable yields. Equipment for hydroponics is a complex economy with electronic control of all parameters: temperature, humidity, concentration and speed of supply of solutions.
On the shortcomings of cultivation in the land
Another way to understand what hydroponics is -just to study what drawbacks simple cultivation in the soil can have. When grown in the ground one can only guess about its chemical composition, and often fertilizers and mineral additives are used without taking these features into account. In addition, it is not a secret for anyone that the fertile layer often becomes a hotbed of all kinds of insects, mollusks, fungi and diseases.
Some features of growing in the ground
Perhaps, the only advantage of the soil is,that it is accessible and open, you can simply go out and arrange a garden where you want, this is a traditional and proven method of plant growing for centuries. But even in a closed ground green plantations are not immune from mold, soil acidification.
New on the current market
Because it is worth thinking about how to turn tomodern technological systems. For example, buy a nutrient solution for hydroponics. Although you can use and hydrogel, which in recent years is becoming increasingly popular and spread. True, we use hydrogel for the decorative design of floral plants.
