Excessive nitrogen fertilization can lead to leaf burn, a phenomenon caused by an overload of nitrogen which can create an imbalance of nutrients in plants. When nitrogen levels are too high, plants may produce an excess of foliage while neglecting root health and overall plant balance. This surplus can result in the accumulation of salts in the leaf tissue, which ultimately leads to tissue desiccation and brown, burnt-looking edges on the leaves.

Stunted growth is typically a result of other issues, such as nutrient deficiencies or unfavorable environmental conditions. While improved leaf growth can be associated with adequate nitrogen levels, too much nitrogen disrupts the overall health of the plant by affecting nutrient absorption and causing damage, rather than fostering healthy growth. Increased disease resistance is not a direct effect of excessive nitrogen; in fact, it can potentially weaken the plant by promoting lush growth that is more susceptible to certain diseases. Root development may also suffer due to a lack of balance, as plants focus on producing leaves instead of strong root systems.
