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.
Nitrogen, just like carbon and oxygen, is an essential element needed by living organisms. Proteins are involved in cell control and the growth of new cells. Nitrogen (N2) makes up about 80% of the atmosphere but plants are unable to take in nitrogen from the atmosphere. Most plants can only absorb nitrogen in the form of . nitrates. from the soil.
