Vedclass · Answer

(A) $N, P, K$ (Nitrogen,Phosphorus,and Potassium) are known as critical elements because they are frequently deficient in the soil. This deficiency occurs primarily because these elements are required by plants in relatively large quantities (macronutrients) and are also prone to loss from the soil through processes like leaching. Therefore,both the Assertion and the Reason are correct,and the Reason provides a valid explanation for why they are termed critical.

$A$ : $N, P, K$ are called critical elements.
$R$ : They become deficient easily in soil due to leaching and higher requirement.
