Detailed explanation-1: -Phosphorus is a vital component of DNA, the genetic “memory unit” of all living things. It is also a component of RNA, the compound that reads the DNA genetic code to build proteins and other compounds essential for plant structure, seed yield and genetic transfer.
Detailed explanation-2: -Phosphorus (P) is an essential element for plant growth and development but it is often a limiting nutrient in soils. Hence, P acquisition from soil by plant roots is a subject of considerable interest in agriculture, ecology and plant root biology.
Detailed explanation-3: -Nitrogen: found in chlorophyll, nucleic acids and amino acids; component of protein and enzymes.
Detailed explanation-4: -Phosphorus is used for root and seed production, and it is also essential for DNA replication to form cell walls and complete the reproduction cycle. Potassium is important for the vascular system of the plant to move nutrients throughout the plant. Potassium also improves the flavor of many fruits and vegetables.
