Question

Whyis purification of water and nutrient salts so important in studiesinvolving mineral nutrition using hydroponics?

Answer 1

Hydroponicsis the art of growing plants in anutrient solution in the absence of soil. Since the plant roots areexposed to a limited amount of the solution, there are chances thatthe concentrations of oxygen and other minerals in the plant rootswould reduce. Therefore, in studies involving mineral nutrition usinghydroponics, purification of water and nutrient salts is essential soas to maintain an optimum growth of the plants.
