UNDERSTANDING
NPK
FERTILISER




Plants require a range of nutrients for healthy growth. These nutrients occur
naturally in the soil and can also be added in the form of fertilisers, to
boost growth rates, performance, and crop yields.



What does NPK mean?

The three major nutrients that plants need are nitrogen, phosphorus,
and potassium.

These are referred to by the initials of their chemical symbols:



N (Nitrogen)

P (Phosphorus)

K (Potassium)

WHAT
IS THE
N-P-K
RATIO?




Plants need many nutrients to grow and thrive, but there are three
that they typically need large amounts. These nutrients are nitrogen,
phosphorus, and potassium and the three together are found in most
fertilizers under the term N-P-K ratio. The ratio is listed because
each plant type of plant needs a varying amount of these primary
nutrients.

The first number in the sequence will always tell you the nitrogen
level, the second will tell you phosphorus and the third will tell
you the potassium amount. Any remaining weight not accounted for
in the N-P-K ratio is the bulking agent or filler of the fertilizer.
