NPK fertilisers contain compounds of nitrogen, phosphorus, and potassium to improve agricultural productivity.

What does the "K" stand for in NPK?

What is NPK Fertilisers | Practice?

"Complex fertilisers containing the three main elements for plant growth: Nitrogen, Phosphorus, and Potassium."

Question 1

What do the initials NPK stand for in fertilisers?

Question 2

Which of these is a common salt of nitrogen used in NPK fertilisers?

Question 3

Where do the potassium salts for NPK fertilisers come from?

NPK Components

N = Nitrogen (for leaf growth).

P = Phosphorus (for root growth).

K = Potassium (for overall health).

Mined salts (Potassium Chloride) are used directly.

Exam Tip

Production Tip: Ammonium nitrate is a primary NPK component made by reacting ammonia with nitric acid.
