Which essential nutrient is often associated with leaf green color?

The essential nutrient that is often associated with leaf green color is nitrogen. Nitrogen plays a critical role in the formation of chlorophyll, the pigment responsible for the green coloration in plant leaves. Chlorophyll is vital for photosynthesis, allowing plants to capture light energy and convert it into chemical energy. When nitrogen is abundant in the soil, plants are able to produce sufficient chlorophyll, leading to vibrant green leaves and healthy plant growth. A deficiency in nitrogen typically results in yellowing leaves, a condition known as chlorosis, which emphasizes the importance of this nutrient in maintaining the green color of foliage.
