The Hanna Test Kit determines Potassium in soil via a turbidimetric method.
Potassium is precipitated in a basic environment with sodium tetraphenylborate, and the developed turbidity is proportional to potassium concentration.
Dilute the original sample and perform the test again, reading the value from the Graduated card and multiplying it by 5.
