Why is purification of water and nutrient salts so important in studies involving mineral nutrition using hydroponics?
Hydroponics is a hydroculture, a method to grow plants in the absence of the soil, by using the mineral nutrient solution by using the water as a solvent. Terrestrial plants can be grown by only exposing their root to the nutritious liquid.
Hydroponic studies are used for the identification of roles and the functions of several elements in the plant’s physiology.
