Plants and animals need nitrogen in order to make proteins. Proteins are essential compounds for healthy growth and fully functioning organisms. However, nitrogen is often in short supply to plants in both natural and agricultural systems. If nitrogen supply limits the growth of plants then the animals which feed on the plants will also suffer.
What role does nitrogen play in plant growth and yield? Nitrogen occurs in the chlorophyll of plants and is responsible for vegetative. growth. The leaves of plants that receive sufficient nitrogen have a dark, blue-green colour, which promotes photosynthesis. Photosynthesis is the process by which light energy is intercepted by plants. and stored in the form of starches and sugars.
