Hydroponic crops include cultivation techniques implemented in the absence of the common agricultural land, practically without the soil, that is, with the root immersed in a liquid solution.

These crops include a wide range of systems, in which the supply of water and nutrients is carried out by means of the radical 'draft' in an aqueous mixture in which the nutrients for it are dissolved. nutrient.

"Soilless'' crops can be divided into 'substrate crops' and' crops without substrate or liquid medium '.

In the former, the roots sink into an organic, inorganic or artificial substrate which is continuously irrigated with nutrient solution, in the latter the root system is immersed in the nutritional substrate.

Hydroponic crops belong to this last type, which are an alternative when the soil is not suitable for the healthy growth of the plant.
