Plants need nitrates to develop green leaves. Nitrogen, potassium and phosphorus are the three major nutrients plants need to grow successfully. In particular, nitrogen is responsible for foliage development. Plants use nitrogen in the form of nitrates, which is nitrogen mixed with oxygen. They usually absorb nitrates from the soil.
Of all the essential nutrients, nitrogen is required by plants in the largest quantity and is most frequently the limiting factor in crop productivity. 1  In plant tissue, the nitrogen content ranges from 1 and 6%. Proper management of nitrogen is important because it is often the most limiting nutrient in crop production and easily lost from the soil system. Nitrogen Forms and Function Forms of nitrogen available for plant uptake Ammonium; Nitrate; Functions of nitrogen in plants Nitrogen is an essential element of all amino acids. Amino acids are the building blocks of proteins. Nitrogen is also a component of nucleic acids, which form the DNA of all living things and holds the genetic code.
