3.Soil nutrient tester test efficiency:

The medium-speed-acting N, P, K and other nutrients in soil are leached and measured at one time (drafted by the Ministry of Agriculture’s industry standard).

Nutrients such as nitrogen (N), phosphorus (P), potassium (K) in fertilizers are detected simultaneously, quickly and accurately.

Test speed: Under normal proficiency:

It takes 20 minutes to measure one soil sample (N, P, K) (including preparation of agents and pretreatment time for soil sample).At the same time, three soil samples (N, P, K) are detected ≤40 minutes, and 8 soil samples are measured ≤1 hour.

Test one fertilizer sample (N, P, K) for 50 minutes, and test three fertilizer samples (N, P, K) for 1.5 hours at the same time.

4.Soil nutrient tester test error:

The soil nitrogen, phosphorus and potassium error is ≤1%, the organic matter error is ≤2%, and the trace element relative error is ≤5%; the fertilizer single error is ≤0.5%, and the nitrogen, phosphorus and potassium three error is ≤1%.
