Question 1

What is an NPK soil tester?

Accepted Answer

An NPK soil tester is a digital meter that measures the three core plant nutrients in soil — Nitrogen (N), Phosphorus (P) and Potassium (K) — along with pH, moisture and EC. It tells you what your soil is lacking so you can fertilise accurately instead of guessing.

Question 3

How do you test NPK in soil?

Accepted Answer

Insert the stainless-steel probe into moist soil (around 20%+ moisture), wait a few minutes for the readings to stabilise, and read Nitrogen, Phosphorus and Potassium values directly on the digital display or connected app. No reagents or lab needed — the meter is reusable for unlimited tests.
