Nitrogen Deficiency in Plants By Matt Bennett Nitrogen plays a vital role in all plant growth and development. It is one of the most important macronutrients because it is essential for virtually all biological processes. Nitrogen is the main component in protein and chlorophyll, which is responsible for carbohydrate production, it is used in the production of protoplasm which aids in cell division and growth, it provides a source of important vitamins like thiamine and riboflavin, and it is also part of both DNA and RNA. Nitrogen deficiencies can cause a plant to become weaker, slower growing, and faster aging, which make them susceptible to pathogens. There are numerous causes for a plant to become nitrogen deficient. Signs of nitrogen deficiency are usually easy to recognize, and with proper soil and water management most of these causes and symptoms can be eliminated. Nitrogen makes up amino acids which are combined to form proteins and nucleic acids. Proteins provide the building blocks for chloroplasts, mitochondria, and other structures that are critical for most biological processes. Nucleic acids like deoxyribonucleic acid (DNA) duplicates the genetic information in the chromosomes of the parent cell to the daughter cell. Ribonucleic acids (RNA) carry out instructions coded withing DNA molecules. Most enzymes controlling these metabolic processes are also Nitrogen formed proteins and are constantly being metablolized and resynthesized. While being essential for the formation of
