    In a classroom discussion, three students made the following statements.

    Shikha: Fertilizers are chemical substances that are rich in a particular nutrient.
    Ritesh: Fertilizers increase the water holding capacity of the soil.
    Abhishek: Fertilizers used in excess provide lots of humus to the soil.

    Which student(s) made incorrect statement(s)?
    Solution
    • Fertilizers are chemically synthesized substances that are rich in plant nutrients such as NPK. 
    • They are artificially made but have a rapid response. It is added to soil or applied to plant tissues to supply one or more plant nutrients essential for the growth of plants. So, the statement given by Shikha is correct.

  • Question 5

    Which nutrient is not supplied to crops via fertilizer?
    Solution
    Nitrogen, potassium, and phosphorus are required for the growth of plants in more amounts. These nutrients are absorbed in the form of salts from the soil. However, when the supply from soil is inadequate they are added as fertilizers. Iron is obtained from the soil in sufficient amounts as per the requirement of the plants. So, they are generally not added as the fertilizers. However, there are iron fertilizers which can be added when the soil is deficient in iron. 
    Thus, the correct answer is option C.
