A farmer adds/ supplies Na, Ca, Mg and Fe regularly to his field and yet he observes that the plants show a deficiency of Ca, Mg and Fe. Give a valid reason and suggest a way to help the farmer improve the growth of plants.

Solution: A farmer frequently adds/supplies Na, Ca, Mg, and Fe to his field, but the plants still show signs of Ca, Mg, and Fe insufficiency. This is because when the pH is not maintained, the soil becomes infertile. Increased alkalinity or acidity in plants prevents them from absorbing nutrients from the soil. It can also lead to an iron shortage.

The pH of the soil is maintained, and top-grade fertilizers are used.
