Basic Knowledge in Agriculture #28

Hydroponics.

In any field of activity people try to simplify production processes reduce production costs improve something and mechanize the process and in the agricultural sector this is also observed.

One example of this is hydroponic systems which allow you to grow plants even where there is no fertile soil a priori or in some cases this allows you to get rid of crop damage by root pests and of course this negates the need to fight weeds which is labor-intensive.

Let's start with the fact that if the animal world can be divided into terrestrial and underwater then with plants everything is not so clear.

Water light and microelements carbon dioxide this is essentially what any plant needs and soil in this case is a bonus for the plant but not a necessary condition.

All of the above can be obtained by the plant both on the surface of the water only by lowering the root system into it and under water.

When we buy a bunch of lettuce in a supermarket the probability that it was grown hydroponically is very high as a rule these are very clean-looking plants without any significant damage to the leaf.

It is believed that lettuce is profitable to grow on hydroponic farms adding phosphates nitrates urea potassium sulfate and magnesium sulfate to the water.

These are the most essential elements that both grass and trees need, both on the surface of the earth and under water.

Hydroponics has its pros and cons.

I have already mentioned the pros and as for the cons if you want to grow seedlings hydroponically and then plant them in a greenhouse or in open ground the plants will start to get sick it will be a big stress for them.

The transition from hydroponics to open ground is a long process acclimatization which should take place in conditions of high humidity for example with the help of foggers and this works both ways.

I have some experience in transferring terrestrial forms of plants to an underwater form I often taught terrestrial mosses to live underwater as well as Riccia which usually floats on the surface of the water and I made it breathe underwater.

In this photo you can see a glass with a fiberglass substrate in which an aquarium plant called Echinodrus grows.

Suppliers of such plants are cunning, they grow them hydroponically and then sell them to aquarists who as a rule will very soon lose this plant due to its death and will come again for a new purchase.

Imagine that this glass is held above the surface of the water and only the roots touch the water this is how most hydroponic systems are arranged.

In fact such a plant is much weaker than a plant grown in harsher conditions.

So, getting seedlings from plants grown hydroponically is very difficult but you know even tomato seedlings are sometimes grown hydroponically by unscrupulous sellers and sold to unsuspecting gardeners.

Hydroponics is good when everything is honest here is a salad here is money for a salad grown using intensive technologies and nothing more as it seems to me :)

All my photo shots and art works are what I did with my own hands as is the design of my aquariums.

I invite my friends @eii @ranartblog @xaviduran to take part.

Zoom in on a photo for a closer view.
