Soil testing kit (25) (nitrogen-phosphorus-potassium-pH)

MACHINE TRANSLATION (not authorised yet)

The set enables to perform 25 tests (4x25) and determine the level of phosphorus, nitrogen, potassium and pH in the tested soil mainly by colorimetric method (according to the color scale). The tests are performed very simply and quickly thanks to the extraction solution, which enables immediate testing of the prepared soil sample. The colour obtained as a result of the chemical reaction should be compared with the colour chart and the level (concentration) of a given element in the soil sample tested should be determined as trace, low, medium and high. In the case of pH, we determine its level from 4 to 9. It contains reagents and necessary containers.
