Hydroponics is the technique of growing any plant without implanting it in soil.
A couple of years back, botanists discovered that plants soak up nutrients through the water which soaks the soil around the roots. Soil works as a reservoir for things like nutrient material and as a medium by which the plant may strengthen itself. When the water supplied to plants already has the needed organic material, and plants are secured or even suspended by other method, then soil becomes unnecessary.
This discovery of this kind of farming excited botanists but wasn’t a popular opinion in its early days. It’s popularity, and adoption grew as concerns over the use of pesticides, as well as other toxins in plants produced in large scale farming grew.
Plants produced by hydroponic techniques do not have any pesticides; therefore, they pose absolutely no danger to humans.
This kind of farming has also been introduced in the first world nations, thus creating an increase in food production dealing with the economic issues and making the country environmentally friendly to have its own supply and then export the produce in neighboring countries.
Techniques of Hydroponic Farming
Generally, there are 2 techniques of hydroponic farming. These include the solution culture and the medium culture.
The medium culture uses a medium to handle the system, such as the sand, the gravel and rock wool culture. On the other hand, the solution culture usually does not use solid media for the technique, but only the nutrient solution.
Then, you must select one of two methods to supply nutrient-enriched water to the plants.
One of the methods is passive method, which normally requires watering manually, which is useful to small projects. The other one is the active method, which is mostly use by larger hydroponics farming, it uses pumps to deliver nutrition.
This type of farming is the future of agriculture. With the increasing world population and more demand for land for non-agricultural purposes, Hydroponics is key to global food production.
