According to agricultural experts, understanding nutrient mobility is one of the most critical skills for diagnosing plant deficiencies. But what are mobile and immobile nutrients? The key difference lies in whether the plant can redistribute the element from older to newer tissue when supplies are low.

A plant's ability to reallocate essential elements from older to younger tissues is a primary survival strategy during nutrient scarcity. Understanding what makes a mobile nutrient mobile is fundamental to diagnosing plant deficiencies and optimizing nutrient management. This internal recycling process determines where deficiency symptoms first appear, offering crucial clues to a plant's nutritional status.

Nitrogen is a critical macronutrient, forming up to 50% of the dry matter of protoplasm in plants. When a plant lacks this vital element, the most observable indicator of a nitrogen deficiency is a distinct and progressive yellowing, or chlorosis, of its older foliage.
