What is one effect of applying too much nitrogen to plants?

• A. Increased plant height
• B. Enhanced photosynthesis
• C. Foliar burn causing leaf damage
• D. Boosted flowering and fruiting

Answer: (C)

Applying too much nitrogen to plants can lead to foliar burn, which causes leaf damage. This occurs because excess nitrogen promotes rapid growth that often surpasses the plant's ability to take up water, thereby causing the leaves to become stressed and exhibit symptoms such as browning or curling at the tips. This damage can reduce the overall health of the plant, impair its function, and ultimately decrease its productivity. While increased plant height and boosted flowering may seem beneficial at first, they do not accurately reflect the adverse effects of excess nitrogen, making foliar burn a critical issue related to nitrogen over-application. Enhanced photosynthesis is also linked to appropriate nitrogen levels rather than excessive amounts, further supporting the focus on proper nutrient management.
