In agricultural applications, monitoring the quality of the soil is extremely important for the healthy growth of crops. The pH level is an excellent guide as to which plants may thrive in a particular terrain, as well as indicating which fertilizers to use. HANNA Instruments® combination test kits allow youth test not only for pH, but for nitrogen, phosphorous and potassium as well, which are just as important for the quality of soil. HI 3895 and HI 3896 are very easy to use: The sample of soil, diluted in water, reacts with the chemical reagents supplied in the kit. The result is a colored solution which is compared to the chart provided to determine the concentration of the element tested. The concentration is given in easily-understood trace, low, medium and high ranges.

HI 3895 comes with all the necessary components for 10 tests.
