Can it be watered with sea water?

Pour hot water on the anthill

Surely you think that it is a crazy idea, since the vast majority of plants live far from the beaches, but the truth is that when you live in an area where it hardly rains it can be very interesting. For example, in many parts of the Mediterranean region we can spend several months (in my area, up to five in the worst years) without receiving a single drop of rain; On the other hand, as we have the sea relatively close, we can take advantage of it.

In addition, it must be taken into account that 3% of the water that the planet has is sweet, but that only 0,06% is usable since the rest is frozen. So, Why not water with sea water? Here's how to do it.

Solar irrigation technique

Materials

You will need the following:

  • An empty 5 liter (or larger) water bottle without the bottom
  • A 1-2l bottle cut in half
  • Seawater

It is also important to have an area where the sun is abundant.

Step by step

It is the following:

  1. The first thing to do is a hole next to the plant.
  2. Then, the lower half of the cut bottle is buried next to the plant, without completely covering it.
  3. Finally, it is filled with water and covered with the upper half of the 5l bottle.

Thus, we will immediately see that the water evaporates, condenses on the walls and falls to the ground without salt.

Plastic bottle

Why use this technique?

As we have mentioned, in areas where it rains little it is a very interesting way to take advantage of seawater. Obviously, if we use it directly we would charge the plants, but With the solar irrigation technique we will not have to worry because the salt will always remain in the tank (that is, in the bottle that we bury a bit). What's more, By reusing plastic bottles we help take care of the Earth.

So nothing. What do you think of this technique? Have you ever put it into practice?
