What "nitrogen" means in gardening

Nitrogen is a key nutrient required for plant growth and development. It is essential for the formation of chlorophyll, which enables plants to perform photosynthesis, and also plays a crucial role in the synthesis of proteins and other essential molecules. Nitrogen is found in many forms, including ammonium, nitrate, and organic compounds, and can be obtained from various sources such as fertilizers, compost, and legumes. Maintaining proper nitrogen levels in the soil is important for ensuring healthy plant growth and productivity.
