What are the three elements of fertilizer?

All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) – phosphorus(P) – potassium(K)).

Which of these is a major component of most Fertilisers?

Most fertilisers supply nitrogen, phosphorus and potassium. The other elements needed by plants are required in much lower quantities (trace elements) and are generally available in most soils. In nature, nitrogen, phosphorus and potassium often come from the decay of plants that have died.
