Why is purification of water and nutrient salts so important in studies involving mineral nutrition using hydroponics. | NCERT solution | Class 11 Biology | Unit-12 Mineral Nutrition



Q.2:- Why is purification of water and nutrient salts so important in studies involving mineral nutrition using hydroponics.

 

Answer:- 



Impure water and salts contain a large number of soluble minerals and impurities. When such water and salts are used as solution culture for growing plants in hydroponics then the impurities will interfere with the experiment and will not give correct result about the essentiality of a mineral element. Therefore, purified water with defined mineral nutrients are used in hydroponics.
