The answer to the question of what is soilless agriculture is that the soil factor is eliminated in order to increase the productivity in production by eliminating the dependence on soil and tillage during plant production, to increase the amount of production thanks to different techniques, to avoid being affected by some diseases and pests whose living environment is soil, and to reduce the cost in production in the long run. we can also say that it is a form of agriculture where production is made by using different techniques and environments for the plant to develop faster.

While soilless agriculture is divided into two main headings as water culture, namely hydroponic agriculture and solid media culture, we can examine water culture under three subheadings as aeroponic agriculture, running water culture (NTF), stagnant water culture, and solid media culture under two subheadings as organic and inorganic. Organic and inorganic production have their own sub-titles, which we will see later on.

Hydroponic agriculture is a form of agriculture in which the plant root system is located in a different growing environment from the soil and the nutrients necessary for plant life are sent to the plant root system in different ways in a solution, as it includes the word hydro in it. We have divided the sub-headings of hydroponic agriculture into three as aeroponic agriculture, running water culture (NFT) and stagnant water culture.

Aeroponic agriculture is the cultivation done by giving the nutrient solution to the plant root system in the form of mist or steam at regular intervals in an environment where the plants are hanging.

The other name of the flowing water culture (NTF) technique is the nutrient film technique. The solution poured in this system can be collected in tanks and used again in the same way when necessary.

In the stagnant water culture technique, it is an aquatic farming technique where the root systems of the plants are suspended in a pool filled with nutrient solution and the water in the tub is prevented from getting light, thus providing protection from unwanted bacteria and algae.

As we said, the purpose here is to provide the plant with a clinging environment, other than that, the plant nutrient requirements are given to the plant from the root part by different methods.

We can call the greenhouses that have these systems we mentioned as hydroponic greenhouses, since the soilless greenhouse eliminates the soil factor, it can also be established in areas where there is no soil.

As it is seen, soilless agriculture eliminates very important factors such as tillage, disease and pest harboring, and being tied to the soil, and it is more controlled than soil agriculture, can use very different methods according to production, financial power and environmental conditions, and can be done anywhere. provides convenience.
