What effect does excessive nitrogen have on plants?

Excessive nitrogen in plants can lead to several physiological issues, with causing stunted growth and yellow leaves being a significant effect. When nitrogen levels are too high, plants may experience an overabundance of foliage growth at the expense of root development and overall plant health. This can lead to a condition known as "nitrogen burn," where the leaves begin to yellow due to the excessive nitrogen levels disrupting the balance of nutrients within the plant.

Additionally, plants overloaded with nitrogen might not effectively manage other essential nutrients, leading to deficiencies that manifest as yellowing of the leaves. This condition indicates that while nitrogen is critical for plant growth, an imbalance can result in detrimental effects, hampering the plant's development and overall vigor. The correct understanding of nitrogen's role is crucial for effective agricultural practices and ensures plants receive balanced nutrients for healthy growth.
