Abstract A method for high-speed measuring content of N, P and K in soil, features a colorimetric cylinder (5 ml) trace analysis is used to replace white ceramic board drip analysis, an adjustable trace transfer pipet is used and the classes of labelled liquid colourimetryl/turbidity series are increased by reducing the step difference to speed up measuring process and raise correctness. Its advantages are high accuracy and speed, and low cost.
