| Hanna Part No: HI-3895-schools
This soil kit is extremely easy to use and includes everything you need to measure the 4 main parameters necessary for strong plant growth. Nitrogen, Phosphorous, Potassium and pH can all be measured with this kit, simply take a sample of the soil, dilute in water and then add the supplied chemical reagent. The result is a coloured solution which is compared to the chart provided to determine the concentration of the element tested.
The concentration is given in an easily-understood trace, low, medium and high range scale and the HI-3895 comes with all the necessary components for 10 tests of each of the parameters. Plenty for the average garden.
