What You Should Know About Soilless Farming (Part 1).

 

Yeah, I know what you are thinking. Is it possible to do farming without soil? It is a YES.



No doubt, good soil is the most important and basic need when it comes to farming. Without good soil located in a good place with all the necessary nutrients, farming is impossible. But guess what? The face of agriculture is changing. No more SOILING your hands. Wouldn’t you be surprised that today, farming can be carried out without soil? It is called Soilless farming.

What is Soilless farming?

Soilless farming is a type of farming whereby plants, especially veggies, can be grown without the use and presence of soil. This new type of farming is growing to become the future of agriculture by providing a more sustainable and productive alternative to the traditional cultivation of crops. No more worries if you want to go into farming and there is no land with good soil. Soilless farming has got you covered.

Soil Farming, which is traditional farming, is already disappearing fast because of climate change and intensive farming. According to Food and Agriculture Organization (FAO), it takes 1000 years to generate just three centimeters of topsoil (the top layer of soil that allows plants to grow). It was discovered that a third of all the world’s land already given over to food production and using more could affect the biodiversity of the planet earth.

Do you know that the planet loses an equivalent of 30 soccer fields of land every minute?

Do you know the size of one soccer field?

Can you multiple the size of one soccer field by 30 and then multiply the answer by 60 minutes to calculate for one hour or 1440 minutes to calculate for a day?

Don’t you think that could be dangerous for all of us?

I am certain you would be speechless seeing the size of land consumed per day with soil farming. With soilless farming, there will be less fight with climate change such as soil fertility, land degradation, desertification, and soil erosion. Knowing that soilless farming is the smart way to farm without harming the planet is a banger!

What are the methods of Soilless farming?

Hydroponics

In hydroponics, the plants grow on neutral, solid, and inert media also called substrates. The substrate provide support and moisture retention to the plant grown on it. A nutrient-enriched aqueous solution provides the plants with water, oxygen, and minerals they need to grow. A commercial soilless greenhouse can be up to 20,000 square-foot with revolutionary hydroponic systems which plants with nutrient-rich liquids instead of soil. 


Aquaponics

The term Aquaponics originates from the two words aquaculture (the growing of fish in a closed environment) and hydroponics (the growing of plants usually in a soil-less environment). Another way to do soilless farming is by channeling the wastewater from fish culture into your hydroponic system. Food and Agriculture Organization (FAO) defines aquaponics as the cultivation of plants and aquatic animals in a recirculating aquatic environment.

If you are into fish farming, you have a better chance to engage in soilless farming. The dirty water that is not suitable for your catfish or whatever fish you are culturing contains nutrients necessary to grow your veggies. Don’t waste it!


Aeroponics

There is an alternative method of soil-less culture in growth-controlled environments. This is called Aeroponics. It is the process of growing plants in an air or mist environment without the use of soil or aggregate media. The nutrient solution is continuously sprayed directly onto the plants’ roots. This system is good in urban spaces including in gardens, on roofs, on balconies and, on facades.


It is interesting to know that soilless farming has come to stay and it is easy to operate at whatever capacity you wish. In a subsequent article, we will discuss on how to set up a soilless farming system. We trust you would love to know how.

Now that we have known the different methods of soilless farming, let us look at the advantages and disadvantages in Part 2. Just click here
